产品采用单柱式、水平翻转结构，由一个支柱绝缘子、连体底座、动触头、静触头及手动操作机构组成。相比传统双柱隔离开关，单柱设计占地更小、安装更简便，柱上安装高度适应性强，尤其适合空间受限的农村及街巷配电场景。核心创新在于提供陶瓷与硅橡胶两种绝缘材质选择，可根据具体气候与环境需求精准选型。

设备采用手动操作，通过曲柄杠杆机构驱动，操作力矩小、动作轻便，单人即可轻松完成分合闸。核心安全特性是分闸时动触头与静触头分离，形成肉眼可见的明显断口（断口距离≥180mm），从物理层面确保检修区域与带电线路的彻底隔离，是保障检修人员安全的关键屏障。

广泛用于10kV/12kV 城乡配网主干线 / 分支线、农村变压器进线、户外环网柜、小型工矿企业配电房等场景。作为断路器的配套隔离设备，用于线路检修安全隔离，也可用于日常负荷切换，是户外配电网络中不可或缺的基础关键设备。

Adopting a single-pillar, horizontal flipping structure, the product consists of one post insulator, an integrated base, moving contacts, stationary contacts and a manual operating mechanism. Compared with traditional double-pillar disconnectors, the single-pillar design has a smaller footprint and easier installation, with strong adaptability to pole installation heights, making it especially suitable for distribution network transformation projects in rural areas and urban streets with limited space. The core innovation lies in providing two optional insulator materials: ceramic and silicone rubber, allowing precise selection according to specific climate and environmental requirements.

The device adopts manual operation, driven by a crank lever mechanism. It features small operating torque and light action, which can be easily switched on and off by a single person. The core safety feature is that when opened, the moving contact separates from the static contact to form a visibly obvious break point (with a break distance of ≥180mm), ensuring complete physical isolation between the maintenance area and live lines from the physical level, a key barrier to guarantee the safety of maintenance personnel.

Widely used in 10kV/12kV urban and rural distribution network trunk lines/branch lines, rural transformer incoming lines, outdoor ring main units, and distribution rooms of small industrial & mining enterprises. As a supporting isolation device of circuit breakers, it is used for safe isolation during line maintenance and can also be used as a load switching switch for daily use, making it an indispensable key device in outdoor power distribution networks.
