LW36-126(145) Series Outdoor High Voltage SF6 Circuit Breaker

GCS low Voltage withdrawable switchgear is suitable for the low voltage distribution system in power plant, petroleum industry, chemical industry metallurgy industry, spinning mill, high buildings, etc. lt is especially used in large power plant,petrochemical system and other locations which are required high automatic and computer interface. lt is serviced in the low voltage apparatus distribution devices of generator and power supply system distribution, motor central control and reactive power compensate of3 phase AC 50/60Hz,400V,rated current 4000A and lower.

GCK low Voltage withdrawable switchgear consists of two parts，power distribution center (PC Panel) and motor control center (MCC Panel). lt is universally applied in power plant, city substations,industry and mine corporations,etc., with rated voltage 400V, max operating current 4000A and rated frequency 50/60Hz. lt can be applied as power conversion distribution control of the power distribution equipment like power distribution.electromotor control， lighting，etc.This switchgear is accordance with international standard IEC439 and national standard GB7251(low Voltage switchgear and controlgear assemblies). The main characteristics are high breaking capacity，good performance of dynamic & thermal stability advanced and reasonable configuration，realistic electric scheme，and strong seriation and generality. All kinds of scheme units are combined arbitrarily.A cabinet has more loops to be accommodated, which has many advantages like saving area，beautiful appearance，high degrees of Protection,safety and reliability,and convenient maintenance, etc.

The composite apparatus of FN12-12 and FNR12-12 is three-phase high-voltage switchgear with rated voltage 12kV, rated frequency 50Hz, applying to separate and close load current, closed-loop current, charging current of no-load transformer and cable, to close the short circuit current and assembling equip load switch of earthing switch. lt can bear short circuit current, it is mainly applied as loading control and short circuit protection in downtown distribution station of three-pase rig net or terminal power supply and industrial consumer

FLN36-12D type indoor use high voltage AC load break switch is developed by our company and absorbing international latest technology and according to our domestic standards, completely comply with lEC420,1EC694, lEC129 and national standard: GB3804 “3.6~40.5KV high voltage AC load break switch”,GB1985-2004 “High voltage AC disconnector and earth switch”GB/T11022-1999 “High voltage switchgear and controlgear: General technical requirements” , it is main switch for ring main unit.
