SF6 Load Switch

Kex® is a well-known electrical industry manufacturer in China, and its professional SF6 load switch is famous for its high-quality products and high-quality after-sales service.

SF6 load switch is a kind of switching equipment using sulfur hexafluoride (SF6) gas as arc extinguishing and insulating medium, which is mainly used for load current separation and isolation of medium voltage distribution network (6kV~40.5kV).

Its arc extinguishing mode can be divided into：

▶Puffer-Type Arc Quenching: mechanically compressing SF gas to extinguish arc.

▶Self-Blast Arc Extinction: using arc energy to boost arc extinction.

There are also three types of operating mechanisms：

▶Manual Operating Mechanism

▶Motorized Operating Mechanism

▶Spring-Charged Mechanism

SF6 Load Switch produced by Kex® can be mainly used in the following scenarios:

1. Ring Main Unit, RMU): urban distribution network.

2. Compact Substation: industrial and commercial power supply

3. Wind farm/Renewable Energy: protection of collector system

4. Railway Traction: the catenary is segmented and isolated.

●Characteristics of SF6 load switch

SF6 load switch is widely used in medium voltage distribution network because of its high arc extinguishing ability, compact structure and long life. With the improvement of environmental protection requirements, low SF6 emission or alternative gas technology has become a development trend. If you need the terminology of special environment (cold/high humidity) or intelligent upgrade (digital twin), you can further refine the requirements from Kex®!
