KYNl8A-12 Indoor Type Alternating-Current Metal-Clad Withdrawable
Metal-Enclosed SwitchgearProduct overviewKYNl8A-12 indoor type
alternating-current metal-clad withdrawable metal-enclosed
switchgear (hereinafter referred to as switchgear) is a kind of
mid-set vacuum switchgear. It usually uses ZN22B-12 vacuum circuit
breaker as the vacuum switch,also can be equipped with ZNl2-10
vacuum circuit breaker, or 3AF and 3AH vacuum circuit breakers from
Siemens. It isapplicable for three-phase single-bus power systems
of AC50HZ and voltage class 3-10kV, used for electric energy
receivingand distribution. It is widely used in power plants,
substations, and industrial and mining enterprises. It can be
installed against the wall (not recommended) or not against the
wall. It complies with GB3906-91 A.C. metal-enclosed
switchgear for rated voltages of 3~35kV, DL404-91 Indoor AC high
voltage switchgear panel, IEC298 Alternating-current metal-enclosed
switchgear and controlgear, etc. Technical
