1. Introduction Act as the protecting and controlling unit for grid equipments and industrial mining enterprises' equipments, outdoor SF6 circuit breaker is an outdoor device used in AC 50HZ three-phase 40.5KV power system. It is applicable to locations that need frequent operating in rated current or under repeatedly on/off short circuit current.
2. Features

Excellent breaking performance, short burning arc time, long life;
Mechanical life of more than 3000 times;
Operation frequently, each can be installed 12 current transformers;
New type SF6 MKZ pointer type density meter, pressure gauge reading is not affected by temperature changes;
