High voltage switchboards
High voltage switchboards
Main features:
Metal sheathed removable switchgear, all metal-separated, all operated under closed cabinet door
Vacuum Air Circuit Breakers and Contactors
Simple and effective "five prevention" locking to prevent misoperation
The low pressure part and the high pressure part are completely isolated
Easy to replace circuit breaker, good interchangeability
The cable chamber has ample space to connect multiple cables; heating devices can be added as required to prevent condensation and corrosion
A variety of standard functional units (with or without transformers): generator feed, transformer feed, motor feed, with synchronous bus...
