12kV & 24kV KYN28 Metal Clad Air Insulated Switchgear
General
KYN28 indoor metal-clad withdrawable switchgear(hereinafter short as switchgear)is a complete power distribution device for 3.6~24kV,3-phase AC 50Hz,single-bus and single-bus sectionalized system. It is mainly used for power transmission of middle/small generators in power plants; power receiving, transmission for substations in power distribution and power system of factories, mines and enterprises, and starting of large high-voltage motor, etc.,so as to control, protect and monitor the system. The switchgear meets IEC298,GB3906-91.In addition to be used with domestic VS1 vacuum circuit breaker, it can also be used with 3AH5 from Siemens domestic ZN65A,and VB2 from GE, etc.,it is truly a power distribution device with good performance. In order to meet the requirement for wall mounting and front-end maintenance, the switchgear is equipped with a special current transformer, so that the operator can maintain and inspect it in front of the cubicle.
KYN61-40.5( same as unigear Z3.2) air-insulated metal-clad withdrawable switchgear( hereinafter as "switchgear") is a kind of MV switchgear. It is designed as withdrawable module type panel, and the withdrawable part is fitted with VD4-36E, VD4-40.5 withdrawable vacuum circuit breaker manufactured by Cooper Nature company. It can also be fitted with isolation truck, PT truck, fuses truck and so on. It is applicable to three phase AC 50/60 Hz power system, and mainly used for the transmission and distribution of electrical power and control, protection, monitoring of the circuit.
