Indoor 24kV 230mm SF6 insulated Fuse Load Break Switch for Ring Main Unit

The sf6 load break switch is a kind of switchgear with a simple arc extinguishing device. It uses SF6 gas as the insulation and arc extinguishing medium. It can be used as the closing and breaking load current and overload current. It can also be used as the closing and breaking no-load. Lines, no-load transformers and capacitor banks, etc., all three-position load switches with on, off and grounding functions are simple in structure and affordable. In addition to long life, strong breaking force and other advantages of vacuum load switch, its outstanding advantages are easy to achieve three working positions (on, off and ground), small current (inductance, capacitance) breaking, anti- Strong environmental conditions. Such type of MV load break switch is suitable for promotion and application in urban and rural medium voltage switchgear distribution networks.

Newly developed load break switch, applied on SF6 RMU, with features of high efficiency, safety, reliability, simple structure, flexible operation, interlock reliable, easy to install and so on.

It satisfies with standard IEC94, GB3804, GB16926 and so on.
