High Voltage Earthing Switch (JN15-12)

Product Description

The JN15-12 indoors high voltage earthing switch has the advanced level product which our company collection domestic and foreign earthing switch newest technology develops.After comprehensive inspection,high voltage earthing switchperformance conforms to GB1985 "A.c. high voltage Isolator Earthing switch" and the IEC129 request. Is suitable in 12KV and below, AC/50Hz electrical power system. May with each kind of model high voltage switch cabinet necessary, uses as the earth protection. This switch for integral type earthing switch. By chassiss frame, the supporting insulator, the static contact, moves touches parts and so on knife, main axle, fast spring is composed. Moreover, according to the user need, may match the electrical display unit.

Product characteristic: Designs advanced, the technical performance is reliable
The structure is simple, installs and debugging are convenient
Can fast analysis and synthesis, has the pass to gather ability
The adaptation need, about operates may use environmental condition: The altitude above sea level does not surpass 1000 meters. Surrounding air temperature upper limit +40C;Lower limit -25C, The earthquake intensity does not surpass 8 degrees. Not flammable, explosive dust, chemistry corrosion and fierce vibration place.
