Switchgear: renewal, repair, maintenance, service
Our activity switchgear comprises low voltage gear, low voltage and medium voltage cabinets as well as the range of high voltage.
As basic modules we employ equipment of the following lines:
- LTSIST fuse isolators
- LS 4 up to LS 307 contactors
- MBS motor protective switches
- ME circuit breakers
- Gerapid DC ultrarapid circuit breakers
- Instrument Transformers for low and medium voltage
- ESS electronic controls
Particularly for breakers there is a preference for plug-in technique. It allows a maintenance and inspection of the breaker in service with short intervals. The plug-in breaker will be pushed into the plug holder (firm portion) across sliding rails. After plugging in the breaker the electrical connection of the main conductors is obtained through contact bridges, which are mounted on a mobile frame of isolating material elastically.
