Product Description

indoor 12kv 24kv 36kv SF6 Gas Load Break switch

 

Product Description

GSC is an indoor high-voltage SF6 load break switch, for switchgear with the rated voltage of 12kV/24kV, adopted  SF6 gas as arc-extinguishing and insulation medium, including the three contactors for switching-on and switching-off and to-ground, and is characteristic in its small volume, its convenient installation and operation and its the great adaptability with surroundings.

GSC is an indoor high-voltage SF6 load switch and GSC-SQC SF6 load switch plus fuse combination can function to protect and control the electric equipments for power supply and transformer substations especially being suitable for ring net cabinet, cable branch cabinet and distribution switching substation.

Complied with the standards of GB3804-1990, IEC60256-1,1997, GB16926, IEC60420 etc.

Our latest switchgear with enhanced features and benefits:

1) Increased Insulation Ability

The insulation ability for arc-extinguishing is significantly improved when the switchgear is in an open status. This is achieved by filling the switchgear with SF6 gas at a pressure range of 0.03Mpa~0.04Mpa.

2) Compact Size

We have designed our switchgear to be smaller in size without compromising on safety. By utilizing advanced techniques, we have successfully made the whole size of the switchgear smaller, making it easier to install and handle.

3) High-Quality Material

Our switchgear features a copper contactor with over 99.95% Cu content. This special production process ensures the contactor's excellent abrasion rigidity. We proudly call this material T2 copper.

4) Increased Phased Distance

In order to enhance safety, we have designed our switchgear with a phased distance of 210mm. This particular design extends the air and creepage distance, minimizing the risk of electrical accidents.
