Indoor AC high voltage isolation switch
Outline
TG38-12KV Series indoor AC high voltage isolation switch is a kind of isolation switch with obvious safety fracture, which is designed and developed by our company according to GB1985-2004 High Voltage AC Isolation Switch and Grounding Switch. The isolation switch has the advantages of small volume, simple and reasonable structure, small operation and closing force of spring mechanism, reliable performance and convenient maintenance, etc. It is used in unit with 12KV high voltage fixed circuit breaker and PT, CT. It is a high-cost isolating switch with superior cost performance
Model description
Note: The insulator of the switch can be optionally equipped with a sensor with a live display.
