KYN28A-12 metal clad withdrawable AC metal closed switchgear is widely used in 12kv, 50HZ power system, as power acceptance and distribution, circuit control, protection, monitor device. It is widely applied in power plants, power substations, industrial and mining enterprises, residential districts, tall buildings, schools and other power distribution systems.
Standards
DL/T404 3.6kV~40.5kV AC metal enclosed switchgear and control gear
IEC62271-100 high voltage switchgear and control gear - high voltage AC circuit breaker
IEC62271-200 AC metal enclosed switchgear and control gear with rated voltage above 1KV and below 52KV
IEC60694 common technical requirements for high voltage switchgear and control gear standard
Applications
It is widely applied in power plants, power substations, industrial and mining enterprises, residential districts, tall buildings, schools and other power distribution systems. 
Structure:
KYN28 switchgear is mainly made of two parts: switchgear body and movable parts(handcart). Switchgear body is divided by metal partition into several compartments, including busbar compartment, circuit breaker compartment, cable compartment and relay & meter compartment.
