KYN28-24 Series metal-clad central-mounted type metal-enclosed switch cabinet (short for “switchgear") is a new type of product deigned on the basis of absorbing foreign advanced technology.
KYN28-24 is used in power grid of 3.6 ~ 24KV three-phase ac 50 or 60 HZ, which is as to accept and distribute electric power, along with function of controlling, protecting and detecting electric circuit. It is also available for use in single bus section system.
The cabinet conforms to regulation of
- IEC62271“Rated voltage 1KV above and 52KV below AC metal-enclosed switch cabinet and control equipment”,
- IEC60694“High voltage switch and control equipment standard common technical requirements”,
- GB306“6kV~40.5kV AC metal-enclosed switch cabinet and control equipment”,
- DL/T 404“3.6~40.5kV AC metal-enclosed switch cabinet and control equipment”, with perfect anti-operation function.
