The operating mechanism with spring energy storage ensures fast closing and switching operation (<1000ms).
Operator place: Local/Remote.
11KV LBS equipped with an electronic controller, this sf6 load break switch can be operated locally or with FTU/RTU interface for console operation.
The type of high-voltage bypass type SF6 11KV LBS insulated load switch is divided into manual type and electric type, which is an engineering bypass type load switch used for the maintenance and construction of power distribution cabinet in order to make uninterrupted power supply to distribution lines. This 11kv load break switch utilizes SF6 gas, known for its outstanding insulation and arc extinguishing performance. Inquiry 11kv load break switch price. Check more pole top switches.

The 11KV LBS load switch that uses SF6 gas as insulation and arc extinguishing medium is called the SF6 gas load break switch. It can be used to switch and switch load current and overload current, and it can also be used to switch and switch no-load circuits, no-load transformers, and capacitors and outdoor pole mounted load break switch groups, among others. All three-position load switches with the functions of connecting, disconnecting, and grounding have the characteristics of simple structure and low price. But the load switch cannot disconnect the short-circuit current.
The 11KV LBS SF6 load switch is an excellent load switch that many users have experienced in recent years. In addition to its long electrical life and strong braking force, it has the same advantages as the vacuum load switch. Its outstanding advantage is that it is easy to achieve three working positions (connected, disconnection and grounding), small current (inductance, capacitance) breaking, strong resistance to severe environmental conditions. It is suitable for popularization and application in urban and rural medium voltage distribution networks.
