Product Description
AC HV SF6 breaker is kind of 3 phase AC 50HZ outdoor type breakers. The gas of the SF6 is employed as the arc-extinguishing medium and the dielectric material. It uses the structure of pneumatic arc-extinguishing chamber,and the breaking performance is excellent. It can be widely used in the electrical system whose rated voltage is 40.5kV to control the rated current and short-circuit current, connect the breaker and cut the current in capacitor banks. The current transformers inside are used for measuring and protecting the breaker. The LW8-40.5 breaker is the regenerate type of oil type breaker.
