Industrial and energy building

Complete switchgear (KRU) designed for a complete switchgear (EDM) and dead-end substations (TS) 6 kV, 10 kV, 20 kV, 35 kV AC, 50 Hz, rated current of busbar systems up to 2500 A with isolated neutral installed in areas with a temperate climate indoors (from -25 ° C to +40 ° C). Can be installed in the capital building or quickly erected modular (BMZ).

switchgear kru-1-SInside KRU posted apparatus main circuits: vacuum circuit breaker type SION or 3AH5 (production Siemens) with a spring-motor drive mounted on the track; earthing; voltage transformer; current transformers, surge arresters, capacitive voltage sensors and other equipment.

In CSG provides protection kit (maximum current protection, overload, short-time protection, short circuit protection on the ground, control circuit voltage, AVR, ACR and others.) Made on the basis of microprocessor protection units, as electricity metering, automatic heating relay compartment.

Accession to the external network - cable or tires.
