GAS INSULATED SWITCHGEAR
Energypac Engineering is proud to introduce Gas-insulated high-voltage switchgear (GIS). It is a compact metal encapsulated switchgear consisting of components like circuit-breakers and disconnectors. Our most popular product is 36kV, 31.5kA, 1250Amp. and 2500Amp. The unique design will allow their user to in most confined spaces.
- Robust mechanism based on European design.
- Three pole operation system.
- A fully motor-driven spring-operated mechanism for all ranges.
- Three-position disconnector-based operating system.
- Interlocking between vacuum circuit breaker and disconnector / earthing switch
- SF6 pressure indicator and Auto low-pressure tripping system.
- Environmentally friendly.
