Factory direct GGD KYN GCK XGN Series electrical switch cabinet High and Low Voltage Switchgear
KYN28A series withdrawable indoor AC metal-enclosed switchgear (LSC2B-PI) produced by Tianshui Changcheng Switchgear Group Co., Ltd (hereinafter shorted as “switchgear”) is three-phase AC 50Hz indoor power distribution equipment, and is used to receive and distribute 3.6 to 15 kV network power and take control protection and monitoring to the circuit. It can not only be equipped with EVH1,EVS1P,VS1,3AE breakers, but also can be equipped with imported VD4 vacuum breaker. Standards:GB3906, DL/T404, IEC62271-200, GB/T 14808 Service Condition:The service condition shall satisfy related regulations of GB/T11022 standards, and shall satisfy condensation and filthy II testing ground.
Main features: ▲The cabinet is assembled of aluminum-zinc plates after multiple bending with short production cycles； ▲Full metal clad and isolation; ▲It can be equipped with EVS1P, EVH1,VS1, 3AE & VD4 vacuum circuit breaker. ▲With NC processing and flow-line production, switchgear has high precision and handcart has excellent interchangeability. ▲KYN28A series new intellectualized medium-voltage switchgear equipment;
●Increase the heat capacity of the adapter, and significantly reduce additional temperature rise of connector, spacer plates due to the temperature rise in adapters.
●Clear and reliable division between functional units and compartments.
●Flat-mounted arrangement of bus bar permits good driving and thermal stability.
●The connecting with external cables is completed within the cable compartment, and the cable can be pulled in and out. The zero sequence current transformers are set in the cable compartment, easy for installation and maintenance.
●By the reduced current limiting reactors' matched short-circuit current, the bus bar's voltage could be stabilized at a certain value, the parts'short-circuit components strength requirement could also be reduced.
●The drawer unit has sufficient number of secondary plug-in components to meet the requirement for the numbers of connection points for computer interface and automatic control circuits.
