35kV Oil Immersed Loadbreak Switch
The 35kV Oil Immersed Loadbreak Switch is a medium-voltage switching component developed for safe and efficient current switching inside oil-filled electrical equipment. It is widely utilized in transformer systems where dependable load control, insulation coordination, and operational safety are critical.
Features
Wenzhou Best's contact system of the switch adopts a double-bridge floating contacts type. To provide high mechanical endurance and smooth switching operation our 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.
To strong electrical insulation performance to preventing arc interruption our loadbreak housing are made of Germany BASF PBT.
