25kV 630A Two Position Loadbreak Switch
The 24kV 630A Single Phase Oil Immersed Loadbreak Switch is a specialized switching device developed for medium-voltage oil-filled transformer applications. It enables safe switching and sectionalizing of electrical loads while maintaining stable insulation performance inside transformer oil environments.
Key Feature
Wenzhou Best company is the manufacturer and supplier in China. Our contact system of the switch adopts a double-bridge floating contacts type. The moving and static contacts have excellent contact performance, with low resistance and strong current-carrying capacity. All these contact are made of T2 copper equivalent to C1100 copper.
Housing are made of Germany BASF PBT.

Advantages For Transformer Manufacturers
Compact Structural Design
The switch occupies minimal internal space, making it ideal for compact transformer tank layouts.
The center shaft and housing are compression-molded using raw materials from BASF Germany; this high-performance center shaft and housing assembly effectively prevents the electric arcs generated during contact from breaking down the housing. Improved arc interruption stability.
