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.
