The FWX1-12/630 outdoor SF6 load break switch is suitable for the distribution network with the highest voltage 11kV, the rated current 630A, and the rated frequency 50/60Hz, which can break off and close the load current and overload current in the power system. The load switch is equipped with an intelligent controller to realize the automation of the distribution system.
Features of 12KV SF6 Gas Load Break Switch
The operating mechanism with spring energy storage ensures fast closing and switching operation (<1000ms).
Operator place: Local/Remote.
Equipped with an electronic controller, it can be operated locally or with FTU/RTU interface for console operation.

Working Procedure of 11KV SF6 Gas Load Break Switch
The load switch that uses SF6 gas as insulation and arc extinguishing medium is called the SF6 load 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. Groups, etc., 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.
Intended Use of 11KV SF6 Gas Load Break Switch
The 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.
