Cladding
The hardness of the galvanized steel makes the compartment a nondeformable corrosion-resistant component.
Tank
The SF6 in the tank is at a pressure of 0.3 bar. It is sealed for life after filling.
Routine checks are performed throughout the production process to ensure
closing, and this gives it a service life of 30 years. Therefore, the CAS 36
requires no maintenance on live parts. The tank contains all the live parts.
All the switchgear and controlgear is located inside, together with the busbars
of the switchboard and the fuse compartment. The efficiency levels of the CAS
36 are consistent with the definition of "pressurized and sealed for life" in
accordance with IEC recommendations.
Sealed compartment of a CAS 36 2I + 2Q switchboard
The strength and reliability of the CAS 36 design mean that the occurrence of
failures in the switching equipment is unlikely.
However, in order to ensure human safety, the CAS 36 is manufactured to
withstand an internal arc having the power of a 16 kA short circuit during 1
second or 20 kA during 1 second without putting the operator in danger.
DD0403
The overpressure caused by an internal arc is limited by the opening of a
safety valve in the lower part of the tank, without any consequence for the front
part of the tank.
After type tests carried out for 16 kA /1 s and 20 kA /1 s, the device is in
conformance with the six criteria defined in Appendix AA of the IEC 60295
standard (IEC 62271-200).
The air-blast circuit breaker uses a blast of SF6 gas toward
the region of contact union as breaking technique. This air blast
occurs only as a result of the very high-speed movement of the
switch inside the gas tank, without supplying additional SF6.

Components
Fuse replacement operation
Fuse compartments
PE1501
Each compartment contains three separate fuse holders, single-pole and plug-in,
which facilitate fuse replacement in the event of fuse blowing. The separate fuse
holders are completely sealed and the fuse compartments are therefore floodable.
In the case of the CAS 36, this compartment is fully immersed in the SF6
compartment, also forming part of the tank in which the rest of the switchgear and
busbars are housed. Opening of the access door is locked by earthing of the
corresponding protective switch-disconnector (Q), which earths the two ends of each
of the three fuses.
CF fuses: Basic characteristics and selection table
The fuses to be installed shall be in compliance with the UNE-EN 60282-1
recommendation. It is recommended to use CF fuses provided with a Schneider
Electric thermal striker (in accordance with DIN regulations), due to the low losses
through heat dissipation.
The following table shows the type of Fusarc CF fuse to use for each mains voltage
and for the power of the transformer to be protected. In the event of overloads of ≥ 20%
and/or ambient temperatures ≥ 40°C, please consult us. For the use of fuses of
another type or from another manufacturer, please consult us.

When the elimination of a fault involves the blowing of one (or two) fuses, often the
properties of the fuses which apparently remain intact are in fact weakened by the
action of the short circuit. Returning them to service in these circumstances would
entail a high risk of unwanted fuse blowing for very slight overcurrents. It is therefore
recommended to replace the 3 fuses in accordance with the IEC 60282-1 standard.

General
bb The sections, contacts and dimensions of the CAS 36 connection cable glands are
those defined by the UNE-EN 50181 standard.
bb 100% of epoxy resin cable glands are subjected to industrial frequency dielectric
tests and partial discharge tests.
The cable glands convey the current between the outside and inside of the case
filled with SF6 gas and ensure insulation between the live conductors and frame
earth.
There are two types of cable glands, which are defined by their permissible rated
current of short duration:
bb Type B: 400 A, 16 kA 1 s and 40 kA peak (plug-in) for protection function.
bb Type C: 400-630 A, 20 kA 1 s and 50 kA peak (M16 screw-on) for line function.
How to define connection cable glands
Connection cable glands depend on specific criteria:
Installation:
bb Amperage of connected equipment: 400, 630 A
bb Permissible rated current of short duration in the switch function
bb Minimum length of phase expansion
bb Type of plug-in connector:
vv Plug-in: contact finger
vv Screw-on: threaded connection
bb Plug-in output connector: straight, elbow, Tee.
Installation:
bb Rated voltage of:
vv the cable
vv the network
bb Type of conductor:
vv Aluminium
vv Copper
bb Cross section in mm2
bb With insulant
bb Cable composition:
vv Single-pole
vv Three-pole
bb Type of insulator:
