General Information :

 

Air insulated switchgear panels (AIS), with Megawin Electric make fixed type vacuum circuit breakers (VCB) with Magnetic Actuator Mechanism. The panels and breakers are designed, type tested & complying to latest IEC standards & GCC specifications

 Applicable standards

Complies with IS/IEC 62271-1, 100, 200

 

Product Features
  • Very compact. Low civil cost. User friendly
  • Separate compartments, with metallic partition, for busbar, cable, circuit breaker, low voltage and VT as applicable
  • Eco friendly as arc interruption happened in vacuum and SF6 free
  • Fixed VCB with magnetic actuator mechanism
  • Magnetic actuator mechanism has endurance of 100,000 mechanical operations
  • Provided with all mandatory safety interlocks and padlocks
  • Ready to connect to any remote control & monitoring system and to any SCADA system
  • Sufficient head room in the cable compartment i.e, more than 650mm, for the connection & bending radius of power cables
  • Suitable for single or three core cables, with a maximum of 12 per phase
  • Busbar and cable compartments have tool based access
  • Busbars are made of electrolytic copper
  • Busbar compartment is segregated for each panel for not letting any arc fault to adjacent panels
  • Complete with CTs, PTs, Relays, Meters, Control & Indication devices fully wired up and ready to use

 

Application
  • Transformer Switching
  • Capacitor Bank Switching
  • Motor Switching
  • Feeder Switching
  • Furnace Switching
