AC Metal Enclosed Medium Voltage Switchgear 2000A 40.5KV
General
The main feature of KYN61-40.5 armored mobile AC metal-enclosed switchgear is that the cabinet is equipped with a ZN85-40.5 fully insulated vacuum circuit breaker and a spring operating mechanism, and the cabinet is assembled with steel plate spray. This will improve the wheelbarrow. The matching accuracy with the cabinet and the in and out accuracy of the trolley are very low, and the compatibility is also high. Beautiful appearance, complete solutions, safe and reliable to use.
