Dead Tank Outdoor Circuit Breaker

Source:

General description:

High voltage AC SF6 dead tank circuit breaker is a new generation HV circuit breaker with features of high reliability, miniaturization and convenient operation & maintenance. It integrates circuit breaker and CT, which has compact structure, small occupation, good reliability and little maintenance. The main characteristics:

1. Use design concept of modularization. Flexible arranged, simple and compact product structure, safe and reliable operation, convenient usage and maintenance.

2. Vacuum interrupter of the circuit breaker adopts self-energized arc-extinguishing principle, with strong breaking capacity, short arc time, long electrical life and simple and reliable structure. The full capacity breaking is 20 times. The circuit breaker uses CT26 type spring operating mechanism, its structure is simple and compact, high reliability and little maintenance. The mechanical life is 10000 times. It can meet oil-free requirement.

3. The product is small and light, so it is easy for transportation and installation. The enclosure uses stain resistant aluminum alloy. It has high anti-corrosion capability, little eddy-current loss, low gravity center and strong shock resistance.
