This component has the allowable insulation diameter range in two units. The top numbers are in millimeters (mm) and the bottom numbers are in inches. b) Verify components properly fit the cable and/or mating products. If practical, the insulation diameter is 20 mils larger than the chosen elbow’s minimum allowed insulation diameter and less than or equal to the elbow’s maximum allowed insulation diameter. Refer to cable measurement instructions in NRI 10. The manufacturer’s allowable insulation diameter range for this component is .880-1.110”; Novinium recommends an insulation O.D. range of .900-1.110” to ensure a tight fit c) Read this entire NRI before starting work. d) Have all required tools and supplies on hand and maintain cleanliness throughout the procedure. CAUTION The elbow access port provides direct access to the cable conductor. Contact with the uncovered port or insertion of objects other than the insulated cap or fluid access interface fitting can cause serious or fatal injury. If the cable is energized during injection, removal of the insulated cap and the fluid access interface must be done with a hot stick tool following instructions in NRI 62. 2. Initial Inspection and Diagnosis a) Remove the elbow or other terminations to access the cable strands. Use a probe wrench to remove the probe from the elbow. With a back-and-forth twisting motion, pull the elbow off the cable. Save the elbow and probe for possible re-use if the cable has to be replaced. ©Copyright 2014, Novinium, Inc. All rights reserved. NRI-15-25kV (36) Page 3 of 14 b) Perform the inspection and diagnosis procedures from NRI 10 and NRI 12. NRI12: Electronic Cable Diagnosis & Pinpointing NRI 10: Visual Inspection & Measurement Choose an elbow and connector to match the wire size and insulation diameter. If the existing connector and cable preparation quality are satisfactory and meet IEEE® P1816™ requirements, the existing connector may be kept with the cutbacks modified per the nonextension, or standard templates. If preparation is not satisfactory, remove the existing connector according to NRI 30 steps 1 and 2. c) Determine if extending the cable length is desirable and if a capacitive test point is required. Cut back the insulation shield and insulation per the appropriate template. Existing connector Removal of existing connector Removal of existing connector: see NRI 30 Use the non-extension template on Page 16 Use the standard template on Page 18 Use the #2-2/0 extension Use the 3/0 & 4/0 extension template on Page 20 template on Page 22 d) If the existing connector was kept: Rotate the connector 30 degrees (or 1 full hour position on a clock) in the opposite direction of the strand lay. Firmly tap the top of the connector to open the strands and improve flow. Rotate the connector to open strands allowing flow Tap old connector towards cable If the original connector was removed: Prepare the strands as instructed in NRI 30, steps 8 through 13. The insulation cut back must include a 7/16” gap with strands visible to allow a flow path into the conductor strands. 7/16” gap Prepare new strands per NRI 30 requirements ©Copyright 2014, Novinium, Inc. All rights reserved. NRI-15-25kV (36) Page 4 of 14 3. Do a Flow Test a) Perform a level 2 flow test with a CTA. See NRI 50: Flow and Pressure Testing. You can perform an integrated flow and pressure test using the injection hardware by installing an injection elbow (Steps 6 through 7). b) If a termination using the original connector does not flow, remove the connector and prepare the strands as required in step 1 for new connectors. c) If a splice does not allow flow, consider: Using Sustained Pressure Injection (SPR) Replacing the blocked splice(s) per NRI 33. Recommend replacement of the cable. See NRI 60, step 3. 4. Installing a New Compression Connector If the existing connector was not kept, install a new connector. a) If a standard length connector can be used, go to step 4d. b) If extending the length is necessary, install a coppertop extension and splice connector according to the appropriate template. (Step 2c above) Select the proper coppertop extension and splice connector from the table to the right. c) Fully insert the copper conductor into the splice connector and then slide it completely onto the cable’s conductor. AWG Splice #2, #1 1/0 2/0 3/0 4/0 ALCR9-8-NV ALCR9-NV ALCR10-9-NV ALCR11-9-NV ALCR12-9-NV Extension Copper Top 1-EC-EXTENSION-UPR 1-EC-EXTENSION-SPR Pre-crimp length must match template Use the template to verify the precrimp length is correct. d) Use the crimping tools and dies specified for the connector. See this NRI’s crimp table or NRI 30. Fully insert cable and extension conductors into splice connector e) Crimp the standard length connector or the splice connector for the extension. The connector length should grow about ¼” during crimping. ©Copyright 2014, Novinium, Inc. All rights reserved. NRI-15-25kV (36) Page 5 of 14 f) Orient the cable to minimize cable strain. Assembled length matches template Use the template to verify the length of the connector assembly and 7/16” gap to the insulation are shorter than the maximum post-swage length. 5. Prepare the Termination 7/16” gap a) Prepare and clean the cable termination according to IEEE® P1816™. Necessary steps include: Unwrap and bind concentric neutral wires 1” away from end of elbow. Remove insulation shield as in template. Bevel the insulation end if desired, but no more than 1/8” max. Thoroughly clean the insulation to remove all conductive residue. 6. Prepare the Elbow a) Remove the insulating cap and install the retaining clip. Unwrap and bind neutrals 1” (25.4mm) from end of elbow. 1/8” MAX insulation taper Remove insulating cap Feed the warning tag and pulling eye through the retaining clip slot. Store the insulating cap assembly until installation after injection completion. b) Put the C-clip on the elbow, if it is not already installed. Place the C-clip in line with the injection port on the opposite side. Press on until fully seated. If your injection elbow is an Elastimold® elbow, go to step 7. Otherwise, skip to step 8 on page 10. 7. Install a Reticular Flash Preventer (RFP) RFP – NPN: 1-UP-RFP,E RFP Insertion Tool – NPN: 0-UP-RFPe-INSRT Foam a) Put the RFP, rigid disk first, into the holder. If a holder is not available, skip to step 7d. Rigid disk ©Copyright 2014, Novinium, Inc. All rights reserved. Insert RFP with rigid disk down RFP Insertion Tool Holder NRI-15-25kV (36) Page 6 of 14 b) Press the RFP inserter into the holder until the tip goes through the RFP, and into the small hole in the holder on the underside. The RFP inserter is pushed fully into holder; tip inserts in small hole on the underside. c) Remove the RFP from the holder. d) The RFP must be fully speared on the RFP Inserter with the rigid disk facing out. Verify this is done correctly. The RFP remains on the inserter Correct: The RFP is on the inserter, with rigid disk facing out Wrong: The rigid disk faces the inserter handle e) Insert the RFP into the elbow’s fluid access port using the RFP inserter. Push the shoulder of the RFP inserter firmly against the face of the fluid access port. The RFP inserter is pushed fully into the access port. The RFP will remain correctly installed when the inserter is removed. The RFP will stay in place after the inserter is removed f) Drip 5-10 drops of Novinium Fluid from a bottle into the access port to soak the RFP. Flip Top Squeeze Bottle – NPN: 0-FH-BTTL-40Z-FLIP The RFP may also be wetted before inserting into the access port. The RFP must be saturated to function properly. ©Copyright 2014, Novinium, Inc.

Install the Access Interface (AI) or Fluid Injection Cap (FIC) AI installs on the fluid access port and seals with 2 O-rings O-ring 1 If you are using an AI, continue to step 8a. If you are using an FIC, skip to step 8e. O-ring 2 Release pin with loop a) Verify both AI O-rings are in place and lightly lubricated with silicone grease. Access Interface for 15 & 25kV – NPN: 0-UP-AI-TUBE-QD b) Press the release pin in until it is flush with the open end of the dust cover. c) Feed tie-wraps through the hole and release slot on the dust cover in opposite directions. Feed another tie-wrap into this slot. Feed a tie-wrap into this hole Tie-wrap heads should look like this: Insert the tail of each tie-wrap around the elbow and into the head of the other tie-wrap. Don’t tighten yet and don’t cross the wraps. Head 1 Head 2 Tail 2 into head 1 Heads adjacent AI d) Place the AI over the end of the injection port. Put the tie-wrap heads next to the AI and evenly tight both wraps until the body of the AI rests against the elbow exterior. Tail 1 into head 2 Pull tails Check that the AI is not tilted and both ties are evenly tight. Trim the excess from the tie-wraps. Skip to step 9. Using the FIC Pull tails Cinch tightly and snip off excess Tie wraps do not cross The FIC is very similar to the permanent cap. It is advised to use the FIC retaining clip on the FIC when available for increased safety. The FIC retaining clip MUST be used when required. e) Slide the FIC in the Fluid Injection Cap retaining clip if used. Similar to the permanent cap and normal retaining clip. f) Connect the FIC to your injection tank with tubing, if not so already. g) Fully install the FIC onto the injection elbow. AI is flush and square to elbow FIC The retaining clip must be secured to the C-clip The FIC installs similar to the regular permanent cap h) Secure the retaining clip, if used, to the Cclip on the elbow at this time. The C-clip would have been installed in step 6b. ©Copyright 2014, Novinium, Inc. All rights reserved.

Hose clamp here DO NOT SUBSTITUTE THE SUPPLIED GREASE! Some components require a specific grease to function properly. Changing greases can cause a failure. Avoid grease on strands Lubricate O-ring Call Engineering to check if there will be any problems using other grease. b) Loosely position a hose-clamp on the elbow body. c) Slide the elbow onto the cable with a back-sand-forth twisting motion. Wipe off all excess grease. d) Align the elbow with the compression lug’s threaded hole. e) Remove the protective cap on the probe threads and lubricated the Oring on the probe. Thread the probe into the lug by hand, taking care not to cross-thread. Tighten with the wrench until the wrench bends. 10. Connect the Concentric Neutrals a) Insert an end of No. 14 AWG (2.5mm) copper wire or equivalent through the ground eye on the elbow. Twist tight but don’t damage the eye. b) Twist the neutral wires and connect to ground with the correct connector. The bond wire is attached to the grounding eye Provide adequate slack in wires for elbow operation. c) Check that all cable neutrals extend to within 1” of the elbow. 1” MAX All neutral wires must extend to within 1” of the elbow ©Copyright 2014, Novinium, Inc. All rights reserved. NRI-15-25kV (36) Page 9 of 14 11. Final Elbow Prep a) Tighten the hose clamp on the elbow snugly. Tighten the hose clamp until snug The clamp is correctly tightened when the outer clamp surface is even with the elbow body. Do not over tighten! b) Attach your “Novinium Certified” craft tag to the outside of the elbow. Cover with 2-3 wraps of clear vinyl tape. “Novinium Certified” Craft Tag – NPN: 1-MI-CRAFT Attach craft tag and cover with vinyl tape c) OPTIONAL: Connect the elbow and bushing plug. DO NOT HANDLE THE BUSHING OR ELBOW UNLESS THEY ARE KNOW TO BE DE-ENERGIZED! If possible, lubricate the receptacle of the elbow and mating bushing on the transformer with the supplied lubricant. Operate as shown. DO NOT OPERATE BY HAND. Use a hot stick to energize the elbow. 12. Inject the cable Follow the instructions in: NRI 62: Unsustained Pressure Rejuvenation 13. Disconnect the Injection Equipment Remove the Access Interface (AI) or the Fluid Injection Cap (FIC). Be sure all pressure has been relieved from the cable. See NRI 62. ©Copyright 2014, Novinium, Inc. All rights reserved. NRI-15-25kV (36) Page 10 of 14 Removing the AI Pull the yellow loop Pull the yellow loop on the release pin with a hot stick and bring the AI away from the elbow. Gently nudging the pull ring from side-to-side while pulling will ease removal. Pulling the pin allows the ties to fall away from the AI, which releases it from the elbow. Pull AI If the ties do not release, nudge it with the end of the hot stick. Removing the FIC …then move AI away from elbow With the hot stick, grab the eye of the FIC. Twist the FIC and retaining clip up to 90 degrees, until the retaining clip comes free from the C-clip. Grab the eye with a hot stick and twist to unhook the retaining clip Pull the FIC and retaining clip free from the elbow. 14. Install the Permanent Cap a) Tightly secure the cap to the hot stick. The hot stick’s metal ring presses against the retaining clip during installation. b) Push the permanent cap onto the elbow’s injection port. Check that the retaining clip’s wings are engaging the barbs of the C-clip. If so, the cap is fully seated now. The cap displaces the RFP into the conductive insert of the elbow. Pull cap tight to hot stick with retaining clip Push cap onto injection port Retaining clip wings must engage barbs of the C-clip Cap pushes RFP into conductive insert. ©Copyright 2014, Novinium, Inc.

NRI-15-25kV (36) Page 11 of 14 OPERATING INSTRUCTIONS Before Loadmake or Loadbreak Operation: Loadbreak connectors must be operated with an eight-foot long, fully-insulated “hotstick” type of tool. Remove fluid access interface and install Elbow Cap before operating elbow. For Injection use, the AI is always installed before the elbow is put onto the bushing. Area must be clear of obstructions or contaminants that can interfere with connector operation. Area should allow establishing firm footing and a secure grasp of the hotstick tool. Maintain positive control over the movement of the loadbreak connector before, during, and directly after the operating sequence. Certain operating positions are more advantageous, because of the control, speed, and force required to engage or disengage the elbow. If there are questions on proper operating position, it is recommended that the connectors be operated de-energized. Do not connect two different phases of a multiple-phase system. Before closing a single-phase loop, make certain both ends of the loop are the same phase. LOADMAKE OPERATION: Check appropriate accessory device operating instructions to be sure that the device is rated for energized operation. 1. Area must be clear of obstructions or contaminants that can interfere with connector operation. 2. When preparing the elbow connector bushing, attach the hotstick tool to the Bushing Cap pulling eye. Following the instructions for this accessory, remove the cap from bushing. 3. Securely fasten a hotstick to the loadbreak connector pulling eye. 4. Establish firm footing and positive control of the elbow connector. Withdraw the elbow with a fast, straight, firm motion from the accessory device on the apparatus parking stand. Be careful not to place the elbow connector near a ground plane. 5. Place the elbow connector receptacle area over the bushing plug. Insert the elbow male contact (arc follower portion) into the bushing until the first slight resistance is felt. Resistance is felt when the arc follower portion of the male contact first meets the female contact of the bushing (the contacts are approximately 2” apart). NOTE: DO NOT HOLD IN THIS POSITION BUT IMMEDIATELY PUSH THE ELBOW HOME WITH A FAST, FIRM, STRAIGHT MOTION, which will engage the internal lock on the elbow and bushing interface. Apply sufficient force to engage the internal lock on the elbow connector and bushing interface. Fault Close: 1. It is not recommended that operations be made on known faults. 2. If a fault is experienced, both the elbow connector and the bushing must be replaced. LOADBREAK OPERATION: 1. Place desired accessory device on apparatus parking stand. NOTE: Refer to appropriate operating instructions for accessory device to be used. Be certain it is rated for energized operation. 2. Firmly tighten a hotstick to the loadbreak connector pulling eye. 3. Without exerting any pulling force, slightly rotate the connector in order to break surface friction prior to disconnection. 4. Withdraw the connector from the bushing with a fast, firm, straight motion, being careful not to place the connector near a ground plane. Place connector on appropriate accessory device, following the operating instructions for that accessory. ©Copyright 2014, Novinium, Inc. All rights reserved. NRI-15-25kV (36) Page 12 of 14 VOLTAGE TEST ON Novinium 1-EB-15kV and 1-EB-25kV: The elongated versions of the Novinium 1-EB-15kV and 1-EB-15kV loadbreak elbow connectors manufactured by Elastimold are equipped with integral capacitance test points that can be used to establish whether or not the circuit is energized. All test instruments, equipment, and accessories must be the appropriate type and rating for the application they will be used. Proper functionality must be verified before and after an absence of voltage test, per the individual equipment instructions. When using the test point, complete the following steps: 1. Remove the test point cap with a hot stick. When removing the cap, PEEL OFF AT AN ANGLE rather than pulling directly in line with the test point assembly. 2. Using a suitable sensing device, proceed to determine if cable is energized. DO NOT USE CONVENTIONAL VOLTAGE MEASURING EQUIPMENT. WARNING: THE VOLTAGE TEST POINT IS A CAPACITANCE DEVICE; IT IS NOT DIRECTLY CONNECTED TO THE CONDUCTOR. CONTAMINATION (MOISTURE, DIRT, ETC.) AROUND THE TEST POINT, OR USE OF THE WRONG MEASURING EQUIPMENT CAN PROVIDE A FALSE "NO VOLTAGE" INDICATION ON AN ENERGIZED ELBOW. TO PREVENT SERIOUS OR FATAL INJURY TREAT THE ELBOW AS ENERGIZED UNTIL THE "NO VOLTAGE" TEST POINT INDICATION IS CONFIRMED BY OTHER MEANS. 3. After voltage detection has been made, clean the test point and then lubricate the inside surface of the cap with silicone grease and replace it on the test point. INJECTION APPLICATION SUPPLEMENT: 1. The elbow is deadfront only when the following conditions exist: • The access port is covered with the insulated cap, and • All shields are properly grounded. 2. When the fluid access interface (AI) is installed, the AI, elbow, injection and collection tubes and containers are not shielded and must be treated as energized when used to inject cable rejuvenation fluid. During the injection process, water within the cable may be forced out the collection tube. This water may be a conductive path from the energized conductor through the unshielded fluid collection system. The tubing must be isolated from any grounded surface by a distance greater than 1 inch. The elbow shall not be disconnected during the injection process with the access interface installed. The fluid access interface was designed for non-submersible application only. Water submersion can cause electrical failure of the injection or collection system resulting in an arc to ground.
