CE-TR Cubicles with VTs in withdrawable of fixed version

General Characteristics

CE-TR cubicles in withdrawable version, are designed for voltage from 7,2 up to 36kV, the concept is the VT disconnection by a truck with or without fuses. The cubicles can be utilised for one or three phases version. The CR-TR cubicles are also designed as a component of each MV switchboards and MV panel.

The VTs secondary circuits are connected by an automatic sliding contacts consisting of a fixed part and a moving part mounted on the VTs truck. This system is protected and segregated. The VTs secondary circuit cables come out from the cubicle by an hole in the rear side.

The main funcional characteristics are, Maximum service continuity, Personnel security and against fire risk, Simple inspection and maintenance, Easy operation installation and connection, standardisation.

The VTs truk insertion is prervent if the front door in not closed. The door opening in permited only with the VTs truck in withdrawable position. Metallic shutter is loked in closed position with VTs truck in withdrawable position.
