ZCW□-72.5(126.5)/L Type Open-Type Switchgear Assembly

ZCW□-72.5(126.5)/L Type Open-Type Switchgear Assembly is a complete set of combination electrical apparatus that uses air as the external insulation SF6 gas as the arc extinguishing medium. The control and protection of 72.5KV transmission and distribution systems for three-phase AC can also be used for connecting circuit breakers and opening and closing capacitor banks. Suitable for urban substations, enterprise substations, and mountainous substations with tight land use.

 structural characteristics

 Organically combine circuit breakers, isolating switches, grounding switches, current transformers, busbars, and other components on a grounded steel structure bracket, resulting in a compact structure. It occupies only 30% -50% of the space of the split type, and has obvious characteristics such as saving land and reducing project costs.

 The entire interval is prefabricated in the factory, assembled and debugged before leaving the factory, and transported to the installation site as a whole, greatly shortening the installation cycle.

 Adopting fully validated high-performance arc extinguishing chambers and isolating switches, with minimal maintenance and high reliability.

 The self-supporting busbar prefabricated in the partition factory does not require users to repair the structure.

 Flexible layout and can be used for various wiring methods.

 The circuit breaker can be lowered for maintenance or replacement as a whole, and the power outage time can be shortened to less than 3 hours due to the body failure.
