Product Description

Indoor High Voltage 24kv Load Break Switch

 

Product Description
Indoor load break switch, whose rated voltage is 12kv, 24kv, current 630A.
It adopts SF6 gas as an arc extinguishing and insulation medium.  It includes three contactors for switching on and swithcing off.
It can protect and control the electric equipment for power supply and transformer substations,  expecially suitable for ring net cabinet, cable branch cabinet and distribution switch substation.
This load break switch can be used in high altitude.

Our Switchgear Component with 230mm Phase Distance is meticulously designed, focusing on every detail. It includes the GSC switch disconnecter and load switch, making it an essential component for 230mm phase distance switchgear systems.

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.
