The High Voltage SF6 Circuit Breaker is a high voltage switchgear that uses SF6 (sulfur hexafluoride) gas as an insulating medium and an arc extinguishing medium. It not only has the ability to cut off or close the no-load current and load current in the high-voltage circuit, but also can cut off the overload current and short circuit current through the function of the relay protection device when the system fails to ensure the safe and stable operation of the power system.

Zi Kai High Voltage Sf6 Circuit Breaker Application
High-voltage SF6 circuit breakers are widely used in power systems of all voltage levels, especially in high-voltage and ultra-high-voltage power grids of 110kV and above. Its excellent insulation and arc extinguishing properties make it play an important role in the field of power transmission and distribution where high reliability and stability are required. At the same time, with the improvement of environmental awareness, SF6 circuit breakers, as environmentally friendly equipment, have gradually shown advantages in replacing traditional oil circuit breakers and air circuit breakers.
Zi Kai High Voltage Sf6 Circuit Breaker advantages
High voltage fracture resistance: SF6 gas insulation performance is good, so the high voltage SF6 circuit breaker needs fewer series fractures, improving reliability and economy.
After arc action: SF6 gas decomposition does not affect the insulation, and there is no corrosion after controlling the moisture, the insulation strength does not drop after breaking, and the maintenance cycle is long.
High rated current: SF6 molecule has good thermal conductivity, good cooling contact conductor effect, no oxidation problem, so the flow rate is large.
Small footprint, anti-pollution: High pressure SF6 circuit breaker structure closed, small footprint, good sealing, strong anti-pollution ability.
