Introduction
The JN15 earthing switch is our world-advanced new development designed in reference to the EK6 earthing switch of German GALOR-EMAG company. It has advantages of cutting-edge design, reliable performance, simple structure and ease of mounting and commissioning. The performance not only meets GB1985-2004 requirements, but also complies with German DINVDE670 and IEC129 standards. As a type of electrical components, the indoor high voltage earthing switch works with ABB-UniGear ZS1, ZS2, Siemens-NXAIR, Schneider-Nvnex and Tellhow-KYN28A type medium voltage switchgear.

Service Conditions
1) Altitude: ≤1000m
2) Ambient air temperature: up to 40 ℃, down to -10 ℃, daily range of 15 ℃
3) Humidity: daily average relative humidity less than 95%; monthly average relative humidity less than 90%
4) Earthquake intensity: ≤ 8 degrees
