应用场景：

广泛适用于 35kV 城乡配网主干线、分支线路改造，工矿企业专用供电回路，光伏、风电新能源电站的并网关口，以及铁路、机场等重点基础设施的中高压配电保护，是构建智能化、可靠化户外配网的关键设备。

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 & Protection:

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 “maintenance-free”, significantly reducing long-term operation and maintenance costs and inspection workload.

Application Scenarios:

Widely used in 35kV urban and rural distribution network trunk line and branch line transformation, dedicated power supply circuits of industrial and mining enterprises, grid connection points of photovoltaic/wind power new energy stations, and medium and high-voltage power distribution protection of key infrastructure such as railways and airports. It is a key device to build an intelligent and reliable outdoor power distribution network.
