    • LW8-	40.5	Outdoor High Pressure Ac Sulfur Hexafluoride Circuit Breaker

    LW8- 40.5 Outdoor High Pressure Ac Sulfur Hexafluoride Circuit Breaker

    The circuit breaker is a small outdoor ceramic pillar structure with CT14 spring operating mechanism; the mechanism and body are connected to each other for simple installation, convenient debugging and reliable operation, which is suitable for frequent operation places; the service life of the mechanism is more than 3000 times; the sealing performance is reliable, and the imported sealing gasket is used, and the V-type sealing ring belt is used for dynamic sealing. Spring pressure compensation structure, secondary wiring board of transformer is matched by cooperative enterprises to ensure annual air leakage rate less than 1%. The current transformer is made of microcrystalline alloy material with high magnetic conductivity. The accuracy can reach 0.2 or 0.2s. According to user's needs, 12 transformers can be attached.
