Solid Sealed SF6 Circuit Breaker,
Indoor SF6 Circuit Breaker,
SF6 Indoor Vacuum Circuit Breaker
EVSP vacuum circuit breaker is an indoor switchgear component with vacuum insulation. It can perform frequent operations or break short-circuit current multiple times within the working current range; the mechanical life can be as high as 30,000 times, and the number of full-capacity short-circuit current breaking times Up to 50 times. EVSP vacuum circuit breaker is suitable for reclosing operation and has extremely high operational reliability and service life.
Products are widely used in power plants, power grids, coal mines, airports, petrochemicals, metallurgy, and urban infrastructure construction and transformation projects.
The EVSP vacuum circuit breaker adopts advanced surface treatment technology and lubrication technology to improve the anti-corrosion ability of the product and ensure the reliability of the product during the expected life. Moreover, the primary conductive circuit adopts a solid-sealed pole type and is suitable for hot and humid areas.
