2. 结构优势：单极双柱结构，双刀片触头+压缩弹簧确保接触压力≥120N、接触电阻≤150μΩ，导电稳定；支柱绝缘子可选瓷质（防污型）/复合硅橡胶，爬电距离充足，抗污闪、耐盐雾、抗紫外线。
3. 操作便捷：手动绝缘钩棒操作，力矩小、动作灵活，无需电源，适配全球无电/偏远地区；安装方式灵活，柱上垂直/水平安装，接线简单。
4. 环境适配：工作温度**-40℃~+40℃**，海拔≤3000m，抗震≤8级，适配沿海盐雾、工业污秽、高原、热带/寒带等全球多地域场景；热镀锌底座+不锈钢固件，耐腐蚀、免维护。
5. 应用场景：广泛用于20-24kV户外配网，包括柱上变压器前端、架空线路分段、环网柜、变电站母线隔离、农村电网改造、工业园区配电，符合GB 1985、IEC 62271-102标准。

Description

In 20kV/22kV/24kV outdoor distribution systems, disconnector switches are core equipment for electrical isolation, line sectionalization, and equipment maintenance, requiring clear visible break points, reliable insulation, and stable operation. Conventional disconnectors face issues like pollution flashover risk, cumbersome operation, and high maintenance, making them unsuitable for global diverse climates (high temperature, high humidity, salt spray, heavy pollution) and regional environments.

GW9-24G/630A Outdoor High Voltage Disconnector Switch addresses these pain points:

1. Core Function: Switches circuits only under voltage but no-loadconditions, capable of switching no-load capacitive/inductive currents ≤2A; strictly prohibited from load operation. Self-locks automatically after closing to prevent accidental opening, ensuring maintenance safety.
2. Structural Advantages: Single-pole double-post structure, double-blade contacts with compression springsensure contact pressure ≥120N and contact resistance ≤150μΩ for stable conduction. Post insulators available in porcelain (anti-pollution)/composite silicone rubber, with sufficient creepage distance, anti-pollution flashover, salt spray resistance, and UV resistance.
3. Easy Operation: Manual operation with insulated hook stick, low torque, flexible action, no power supply required, suitable for global off-grid/remote areas. Flexible installation: pole-mounted vertical/horizontal, simple wiring.
4. Environmental Adaptability : Operating temperature -40℃~+40℃, altitude ≤3000m, seismic resistance ≤8 degrees, suitable for coastal salt spray, industrial pollution, plateau, tropical/cold zonesand other global regional scenarios. Hot-dip galvanized base + stainless steel fasteners, corrosion-resistant, maintenance-free.
5. Application Scenarios: Widely used in 20-24kV outdoor distribution networks, including pole-mounted transformer front ends, overhead line sectionalization, ring main units, substation busbar isolation, rural grid renovation, industrial park distribution, compliant with GB 1985, IEC 62271-102standards。
