Electrical Equipment Kyn 11kv Switchgear 

Summary

The TSR-12 (Ⅰ, Ⅱ) series products are secondary power distribution equipment of 12kV system. The main circuit uses solid insulation as the main insulation structure. The conductive components are all enclosed inside the insulation cavity. Is the breaking element. The plan includes Circuit breaker cabinets, load switch cabinets, load switch + Fuse combination electrical cabinets, PT cabinets and metering cabinets. The series products have the following common features:
Isolation switch and grounding switch are completely independent and have fast opening and closing ability.
Three-phase independent poles completely avoid short circuit between phases.
The upper isolation and the upper isolation and the lower isolation and the lower isolation are grounded, and the scheme is complete.
The incoming and outgoing wires use a standard cable outer cone.
The main bus is a solid insulated bus.
The TSR-12 (Ⅰ, Ⅱ) female combined cabinet can be realized in a ring network cabinet through clever design. It takes full consideration of the user’s land cost and input cost to achieve a win-win situation.
