Out door Switch gear

The trend is technology is to design and manufacture FAIL SAFE equipments and the concept of fail safe design has also been incorporated in Medium Voltage Vacuum Circuit Breakers. Through SF6 is a very versatile technology for Switch Gear for wide ranges of rating and ranges of application, vacuum has gained edge over SF6 for medium voltage range due to many advantages.

Vacuum Circuit Breakers are suitable for both Indoor and Outdoor metal clad as well as outdoor porcelain clad applications and for the various duties of application including transformer, capacitor, motor, furnace and provide compatibility to advanced SCAD Aapplication. The compactness of Shreem vacuum circuit breakers finds full utility in various switchboard formulations including multi-panel switchboards, ring main units, RMUs for multistoried building, etc.
