Product Description

ZW20-12 type of outdoor high voltage vacuum circuit breaker

1.General

ZW20-12 type of outdoor high voltage vacuum circuit breaker(hereinafter referred to as the circuit breaker) rated voltage 12kV, three-phase ac frequency 50 Hz outdoor power distribution equipment. It USES vacuum arcing and SF6 gas as dielectric,used to introduce the Toshiba VSP5 gas seal, explosion, insulation structure technology, the outlet and sealing performance catheter improvement, and the overall good sealing, filling SF6 gas inside the leakage, not by external environmental impact. Its spring operation mechanism for a mini design and reliability and stability optimization, USES the straight moving chain main transmission and multilevel tripping system, operating reliability and stability than traditional domestic institutions have increased significantly. The main loop of the axis of the contact between the outside adduction of type chain structure, and its small contact resistance, low temperature

So, ZW20-12 type of outdoor high vacuum circuit breaker is a free maintenance product, is the column in the circuit breaker optimal health.
