Core Performance & Materials:

The core components adopt a high-quality break design, and the arc chute is filled with pure sulfur hexafluoride (SF6) gas. This gas has strong electronegativity, fast arc extinguishing speed and high dielectric strength. Its insulation capability is 2-3 times higher than air, offering far superior breaking performance than traditional devices. Combined with a high-permeability cold-rolled silicon steel sheet core and high-quality conductive circuit, the device ensures low operating force and stable breaking characteristics even under the 35kV high-voltage level, with low no-load loss and extremely high operating efficiency.

Outdoor Adaptability & Cosaint:

Featuring a fully sealed and corrosion-resistant structural design, the outer shell is made of high-quality cold-rolled steel sheet, treated with strict phosphating and electrostatic spraying for anti-corrosion. It achieves a protection level of up to IP65 and above. It can withstand long-term harsh outdoor environments such as heavy rain, sandstorms, salt fog and UV radiation, effectively preventing gas leakage and internal condensation. With a wide temperature adaptation range of -40℃ to +40℃, it meets the outdoor operation standards of most regions in China, especially suitable for cold, high-humidity and coastal areas with strong winds.

Operation & Maintenance:

Equipped with a high-performance spring operating mechanism, it features reliable action, fast switching speed and long mechanical life, meeting the demands of frequent operations. As an insulating medium, SF6 gas has chemically stable properties without aging failure. Coupled with the fully sealed structure, it realizes truly “saor ó chothabháil”, significantly reducing long-term operation and maintenance costs and inspection workload.
