产品采用双柱连体、杠杆传动结构，由两个支柱绝缘子、连体底座、动触头、静触头及手动操作机构组成。核心创新在于采用连体式底座设计，将两柱固定为一体，安装时只需一次性固定底座，相比传统分体式隔离开关，安装效率提升 50% 以上，施工周期更短，特别适合批量安装或工期紧张的配网改造工程。

设备采用手动操作方式，通过曲柄连杆机构驱动，操作轻便、力矩适中，单人即可完成分合闸操作。核心安全特性是分闸时能形成肉眼可见的明显断口，断口距离充足，从物理层面确保检修区域与带电线路的彻底隔离，是保障检修人员人身安全的关键防线。

作为户外柱上设备，GW1-12G/630A 的绝缘子选用高强度瓷质或复合绝缘材料，具备优异的抗紫外线、抗酸雨、抗污闪及抗老化能力。外壳与传动机构经过严格的热镀锌或喷塑防腐处理，防护等级可达IP55以上，可长期耐受 **-30℃至 + 40℃** 的宽温气候及风沙、雨雪等恶劣户外环境，确保在各种气候条件下运行稳定、不卡涩。

广泛用于10kV/12kV 城乡配网主干线、分支线路、户外环网柜进线、工矿企业配电房等场景。作为断路器的配套隔离设备，用于线路检修时的安全隔离，也可单独作为负荷切换开关使用，是户外配电网络中不可或缺的关键设备。

Adopting a double-pillar integrated, lever drive structure, the product consists of two post insulators, an integrated base, moving contacts, stationary contacts and a manual operating mechanism. The core innovation lies in the integrated base design, which fixes the two pillars as one. When installing, only one-time base fixing is required. Compared with traditional split-type disconnectors, it improves installation efficiency by more than 50%, with a shorter construction cycle, making it especially suitable for distribution network transformation projects with batch installation or tight deadlines.

The device adopts a manual operation method, driven by a crank linkage mechanism. The operation is light and the torque is moderate, which can be operated by a single person. The core safety feature is that it can form a visibly obvious break point when opened, with sufficient break distance. It ensures a complete physical isolation between the maintenance area and live lines from the physical level, a key line of defense to ensure the personal safety of maintenance personnel.

As an outdoor pole-mounted device, the insulators of GW1-12G/630A are made of high-strength porcelain or composite insulating materials, with excellent anti-UV, acid rain, pollution flashover and aging resistance. The outer shell and transmission mechanism are treated with strict anti-corrosion processes such as hot-dip galvanizing or spraying, achieving a protection level of IP55 and above. It can withstand long-term harsh climatic conditions such as wide temperature range from -30℃ to +40℃ as well as wind, sand and rain, ensuring stable operation without jamming under various weather conditions.

Widely used in 10kV/12kV urban and rural distribution network trunk lines, branch lines, outdoor ring main unit incoming lines, main power transformation stations of industrial & mining enterprises and other scenarios. As a supporting isolation device of circuit breakers, it is used for circuit isolation during line maintenance. It can also be used as a load switching switch alone, making it an indispensable key device in outdoor power distribution networks.
