Core Structure & Working Principle

Adopting a double-pillar, horizontal flipping structure, the product consists of two independent post insulators, moving contacts, stationary contacts and a manual operating mechanism. The moving contact is supported by the insulator and rotates horizontally around the axis to realize switching. The core advantage is that it can form a visibly obvious break point when opened, which ensures a complete physical isolation between the maintenance area and live lines, a key line of defense for personal safety.

Eskuzko Eragiketa & Adaptability

The device adopts a manual operation method, realizing switching by driving the mechanism through a handle. The operating torque is small and the action is light, which can be operated by a single person. No power drive is required, and the simple structure has a low failure rate. It is especially suitable for scenarios with low automation requirements and focusing on cost and reliability, such as small distribution networks, rural power grids and standby circuits of industrial and mining enterprises. With a rated current of 60A, it is suitable for the disconnection of small-capacity lines or terminal loads.

Outdoor Adaptability & Babesa

As an outdoor device, the outer shell and insulators of GW4-12/60A are all treated with anti-corrosion. The insulators are made of high-strength porcelain materials, which have excellent anti-UV, acid rain and pollution flashover capabilities. It can withstand long-term harsh climatic environments from -30℃ to +40℃, and its protective performance meets the requirements of long-term outdoor operation. It is suitable for urban and rural distribution network trunk lines, branch lines and outdoor ring main unit supporting scenarios.
