1, General Description:
The bank of capacitors vacuum switch ZN12-12/630-12.5J is mainly used in VQC device of substation 10Kv(6Kv) system or in breaking
capacitive loading site (where working actions happen frequently) of power filter. It adopts a modular construction, using flexible busbar
to connect between switches so its volume is small and it is convenient to install inside the cabinet.
2,plication Environment:
1),Air Temperature Around:-40ºC~+40ºC;
2),Altitude should not exceed 2000m. Please negotiate with factory when it is over 2000m.
3),Humidity: relative humidity: daily average value should not exceed 95%, month average value should not exceed 90%.
4),No corrosive, flammable or conductive dust or gas in surrounding medium.
5),Not allowed to install in serious dirtiness or strenuous vibration place.
