Switchgear

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.

 

Shreem with its proven experience in the field of -
  • Design, Development and manufacture of MV capacitors.
  • Turnkey projects in the transmission and distribution system.
  • Various types of Control Panels.
  • Towers

Keeping in view of the growing need for reliable medium voltage applications, has now introduced MV vacuum Circuit Breakers with the latest technology.

 

Shreem presently offer medium voltage Vacuum Circuit Breaker of rating upto 12 kV, 1250 Amps. 25 kA and capacitor switching current upto 400 A. Inception of Vacuum Circuit Breakers for higher voltage range (upto 36 KV) and fault currents upto 40 KA are also in the pipe line.
