12kV Indoor High Voltage AC Earthing Switch

GPJN15-12(7.2)/31.5 type indoor high voltage earthing switch is the assembly type products, its performance meet GB1985-2004 High Voltage AC Disconnector and Earthing Switch and the requirements of standard IEC62271-102:2002. The products suit for power system with 3.6kV-12kV, 3 phase, AC, 50(60)Hz; It has capacity of short-circuit close to protect the electrical equipment from damage, applicable for high voltage switchgear arrangement as the earthing protection when do maintenance.

Altitude sea level not exceeding 1000m;

Ambient air temperature: +45℃ ,-25℃ ;

Seismic intensity not exceeding 8 degree;

Related humidity daily average value not more than 95%, monthly average not more than 90%;

Pollution class: II

Special condition: Please specify when ordering.

When ordering earthing switch, shall specify products model, rated voltage, phase distance, thermal stability current, with or without live indicator device. (If necessary, please specify the monitor model).

If flexible connection lengths required longer. (Standard arrangement of the soft connection length L = 240mm).

Number of the auxiliary switch, terminal needs to lead or not.

Specify the operation direction: Left or right.

About the operation direction of left or right, which is the easiest to mistake when ordering, so my company will be as follows:

Stand in the from of the product, insulator in the top face, the movable blade in the bottom, then the main shaft in the left hand is left operating earthing switch, shown in Figure (1).

Stand from of the product, insulator in the top face, the movable blade in the bottom, then the main shaft in the right hand is right operating earthing switch, shown in Figure (2).

Since the earthing switch can be installed in any orientation, you carefully check the required operation direction, According to the above instruction of Figure (1) and (2), to select the required left or right operating earthing switch.

If any special requirements, please contact with GreenPower to develop detailed specifications.
