GN38-12D Indoor high voltage Disconnect Switches

Structure and Properties:

GN38-12D isolation switch structure design, reasonable, unique. It uses the window wall outlet directly on the busbar

chamber and circuit breakers to form an insulating spacer. It’s easy and input terminals directly connected row jellyfish

cabinet, can be reduced switchgear height, reduced transition joints and reduce costs.The isolation switch operating

mechanism drive shaft rotates, driven operating crank arm sliding isolation blade, making it into the line of contact and division,

or division to achieve isolation and ground contacts or ground.

Working Environment:

1. Altitude: ≤1000m;
2. Ambient temperature: -25°C~+40°C;
3. Relative humidity: daily average ≤95%, monthly average ≤90%;
4. Earthquake intensity: ≤8 degree;
5. Applicable occasions should free from inflammables, explosives, corrosives and severe vibration.
