IRRADIATED CROSSLINKED POLYOLEFIN INSULATED WIRE & CABLE
1.
GENERAL
1.1
Spec. TGN, "General Provisions and Definitions" of the New York City Transit Authority Wire and Cable
Specifications is a part of this specification.
1.2
When there is a difference between the requirements of the Military Specifications or other organizations named
herein and those specified within this Specification the requirements of this Specification shall apply.
2.1
CONDUCTOR: All conductors shall be soft annealed tinned copper conforming to the ASTM-B33 and tables "A"
and "B" herein.
2.2
INSULATION: The insulation system shall have an operating temperature of 110°C (125°C where specified), rated
for 600 V or 2000 V (AC or DC), consist of a thermosetting, flame retardant, oil and grease resistant compound that is
also moisture and abrasion resistant and irradiated crosslinked Polyolefin Insulation in accordance with tables "A" and
"B" herein. The insulation shall be tight fitting over the stranded conductors, but easily removed with either automatic
or manual mechanical stripping - tools, and shall conform to Insulated Cable Engineers Association (ICEA) Standard
S-95-658-1999 / NEMA WC-70, Tables 3-1, 3-4, and 3-7 for Type X-2 (XLPE). Insulation thickness at any point
shall not be less than 90% of the minimum average wall thickness as shown in tables "A" and "B" herein when
measured in accordance with Section 3 of ICEA Standard T-27-581-2000 / NEMA WC-53.
2.2.1
INSULATION COLOR CODING: Color coding shall be as specified in the order or contract specifications. The
colors shall be durable, easily distinguishable, and shall have no deleterious effect on the finished product.
The following abbreviations shall be used to identify insulation color:

Procedure For Qualification:
A. The manufacturer shall have a documented Quality Assurance program that is acceptable to NYCT as to assure the
delivery of a quality product to NYCT within the terms of this specification.
B. NYCT reserves the right to inspect the manufacturer’s facility to assess their Quality Assurance program. The
manufacturer must be prepared to prove, to the satisfaction of NYCT, their quality control procedures and the
necessary facilities, skill, experience and financial resources to perform and deliver the product in a satisfactory and
timely manner.
C. For initial qualification, the manufacturer shall produce 500 ft. samples of a # 12AWG / 600 volt and a # 12AWG /
2000 volt wires and perform all Class A tests and all Class B tests except test numbers 10 & 25. The manufacturer
shall also produce a 500 ft. sample of #2/0 AWG - 2000V cable and perform all Class A tests except test numbers
1,2,3,5 & 21 and only Class B test numbers 10,15,18 & 25. Class A and Class B tests must be performed by an
independent testing laboratory approved by NYCT. The manufacturer shall arrange and incur all costs associated
with performing these tests. NYCT may elect to witness some or all tests performed. The tests shall be performed on
a portion of the wire and cable. All reports covering Class A and Class B tests shall be notarized and submitted in
triplicate, together with the remaining length of wire and cable. The remaining length of cables shall be shipped at no
cost to NYCT for additional testing as deemed necessary by NYCT.
D. Class A tests are required for every lot of up to 100,000 feet of AWG size 8 and smaller and 25,000 feet of AWG
size 6 or larger. For subsequent orders, the manufacturer must perform Class A tests by either an independent
laboratory or in the manufacturer’s facility, and include copies of the Class B tests that were performed for the latest
qualification. Class B tests shall be performed at a frequency of at least once per year. If no order has been processed
during the year, then Class B tests shall be run on the following order.
E. All reports covering Class A and Class B tests shall be notarized and submitted in triplicate, together with two (2)
foot lengths of the sampled test product for review and approval by NYCT, before any delivery of such product. The
notarized test reports shall also contain a certified statement by the manufacturer that the sampled product(s)
supplied has been manufactured with the same formulation used for qualification.
F.
If there is a change of formulation, the manufacturer shall repeat Class A and Class B tests as proof of the design
performance characteristics, as specified under section C above.
