3. 操作便捷：手动绝缘钩棒操作，力矩适中、动作灵活，无需外接电源，适配全球无电/偏远地区的35KV配网场景；安装方式灵活，柱上垂直/水平安装，接线简单，可快速完成安装调试。
4. 环境适配：工作温度-40℃~+40℃，海拔≤4000m，抗震≤8级，适配沿海盐雾、工业污秽、高原缺氧、热带/寒带极端气候等全球多地域场景；热镀锌底座+不锈钢固件，耐腐蚀、抗老化、免维护，大幅降低运维成本。
5. 应用场景：广泛用于35KV户外配网，包括35KV变电站母线隔离、柱上变压器前端保护、架空线路分段、工业园区高压配电、农村电网升级、新能源电站配套，符合GB 1985、IEC 62271-102标准，各项性能指标均满足全球中高压配网的使用要求。

Description

In 35KV 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 to meet the safe operation and maintenance needs of high-voltage scenarios. Conventional 35KV disconnectors face issues such as high pollution flashover risk, cumbersome operation, high maintenance, and poor regional adaptability, making them difficult to adapt to global diverse climates (high temperature, high humidity, salt spray, heavy pollution, plateau) and regional environments.

GW9-40.5/630A Outdoor High Voltage Disconnector Switch specifically addresses the above pain points and is tailored for 35KV high-voltage scenarios:

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. It self-locks automatically after closing to prevent accidental opening and closing, effectively ensuring the personal safety of operation and maintenance personnel and the stable operation of equipment.
2. Structural Advantages: Single-pole double-post structure, double-blade contacts with compression springsensure contact pressure ≥150N and contact resistance ≤120μΩ, with stable conduction and low loss. Post insulators are available in porcelain (anti-pollution)/composite silicone rubber, with sufficient creepage distance (adapting to 35KV high-voltage insulation requirements), anti-pollution flashover, salt spray resistance, and UV resistance, eliminating insulation hazards in high-voltage scenarios.
3. Easy Operation: Manual operation with insulated hook stick, moderate torque, flexible action, no external power supply required, suitable for 35KV distribution scenarios in off-grid/remote areas around the world. Flexible installation: pole-mounted vertical/horizontal, simple wiring, and quick installation and commissioning.
4. Environmental Adaptability : Operating temperature -40℃~+40℃, altitude ≤4000m, seismic resistance ≤8 degrees, suitable for coastal salt spray, industrial pollution, high-altitude hypoxia, tropical/cold extreme climatesand other global regional scenarios. Hot-dip galvanized base + stainless steel fasteners, corrosion-resistant, anti-aging, maintenance-free, greatly reducing operation and maintenance costs.
5. Application Scenarios: Widely used in 35KV outdoor distribution networks, including 35KV substation busbar isolation, pole-mounted transformer front-end protection, overhead line sectionalization, high-voltage distribution in industrial parks, rural power grid upgrading, new energy power station supporting, compliant with GB 1985, IEC 62271-102standards, and all performance indicators meet the usage requirements of global medium and high-voltage distribution networks.
