KYN28A type indoor AC metal armored withdrawable switchgear 
 First, an overview 
 KYN28A type indoor AC metal armored withdrawable switchgear series rated voltage 3-12kV three-phase AC 50Hz single busbar and single busbar system voltage power distribution installations. For the power plant power transmission, electrical systems and industrial and mining enterprises substation of electricity, power distribution and high voltage motor starting, control, protection, detection purpose. 
 The switchgear can meet GB3906, IEC298 standard requirements, and has a circuit breaker to prevent misuse, to prevent negatively Hora handcart to prevent the charged closing earthing switch, to prevent the grounding switch in the ground position when the power transmission and prevent mistakenly charged isolation defense "function. Switchgear can be equipped with ABB, VD4 vacuum circuit breaker, but also with made VS1 vacuum circuit breaker, in fact, a superior performance of power distribution equipment. 
 Second, the main features of 
 ? Cabinet structure is aluminum-zinc plates bolted made after the processing of multiple bending process used by the CNC machine; 
 ? All operations in the state of the door closed; 
 ? High level of protection, to prevent debris and invasive pests; 
 ? Simple and effective anti-lockout, to prevent misuse; 
 ? VS1 and VD4 type vacuum circuit breaker can be equipped with; 
 ? Replace the circuit breaker handcart exchange of good performance; 
 ? Cabinet can be mounted against the wall, before the ark, maintenance, and reduce floor space; 
 ? Cables ample room space, and can be connected to multiple cables; 
 Breaker room and cable room can be the installation of the heater to prevent condensation and corrosion occur.
