KYN61-40.5 armored movable metal closed switch device used in 40.5kV three-phase AC 50Hz power system, for power plant electricity, power system substation distribution, industrial and mining enterprises distribution and otheroccasions; with control, protection and monitoring of the circuit function. To prevent the load push-pull circuit breaker handcart, prevent false divisioncircuit breaker, circuit breaker, close together to prevent the grounding switchis in the closed position to prevent mistakenly charged compartment, preventmisconnection interlocking functions of grounding switch in charged, power distribution device is a superior performance.

KYN61-40.5 armored movable metal closed switch device is made of high quality aluminum zinc plate by CNC sheet metal processing equipmentbending, the high strength bolt, nut (8.8) or a pull riveting nut assembly.Each member body using spray or galvanized surface process, so that thebody has not only high precision, but also has the features of light weight,high mechanical strength, beautiful appearance compared with the similar equipment. At the same time as a result of the assembled structure of thestrong versatility, short processing cycle, production covers an area of small,easy to organize production according to orders. The KYN61 - 40.5 type armoured metal closing switch device is mainly composed of two parts the cabinet and circuit breaker handcart etc.. The cabinet body is divided into acircuit breaker chamber (also known as the cart chamber), bus room, cablechamber and low pressure chamber four separate compartments. Shellprotection class IP4X, open the door when the circuit breaker protection class IP3X. The breaker handcart is composed of two parts of circuit breaker and chassis components, and has import and wire, cable, overhead line contactmeasurement, import, isolation and other function scheme.
