General instructions

cpg

.0: GIS medium-voltage switchgear,

gas insulated, up to 40.5 kV,

in accordance with IEC Standard

Fuse compartment

The

cpg

.0-f fuse-protected cubicle has independent fuse

holders to house limiting medium-voltage fuses.

The compartments are pipe-shaped and are fully positioned

in the gas tank, meaning they are insensitive to pollution.

A carriage is used to extract and introduce the fuses in the

fuse carriers, thus simplifying operation and ensuring the

correct positioning of the fuse.

The pipe seal consists of an elastic membrane with the

following functions:

• To maintain the sealtight integrity of the fuse carriers

from flooding, and therefore avoid pollution and interior

degradation.

• Additional isolation provided by the isolation of the fuse

holder carriage itself.

• To transmit the movement of the fuse striker to the

switch tripping mechanism, while maintaining the

sealing of the fuse carrier.

By the very nature of its construction, this sealed solution

is subject to the internal overpressure caused by abnormal

overheating of the interior air. The trigger device can, in

this case, act as protection against overheating, preventing

damage both to the fuse and to the fuse carrier.

Fuses compartment detail

Exterior cable connections (bushing)

cpg

.0 cubicles have bushing on the front for medium-

voltage cable connection. These are made of epoxy resin

and can, thanks to their configuration, withstand the

current transformers. They are duly screened and designed

in line with Standard EN 50181, type "C".

They allow conductors to be connected via screwable

T-type connectors of any manufacturer.

The cable clamps in the cable compartment hold the

cables at their input to the cubicle and prevent the

connector and bushing combination from supporting

the weight of the cable.
If cable input/output is via a trench over 2 m deep,

the cables must be fastened with additional cable

clamps, depending on the depth of the trench and the

cable cross-section (weight), in order to prevent the

connector and bushing combination from supporting

the weight of the cable.
