36kv SF6 Indoor Load Break Switch (RLS)
++++General:
RLS-36 an indoor high-voltage SF6 load switch, an switchgear with the rated voltage of 36kV/40.5kV, adopted with SF6 gas as an arc-extinguishing and insulation medium, including the three contactors for switching-on and switching-off and to-ground, and is characteristic in its small volume, its convenient installation and operation and its the great adaptability with surroundings. RLS-36 of an indoor high-voltage SF6 load switch and RLS-36 of SF6 load switch plus fuse combination can function to protect and control the electric equipments for power supply and transformer substations especially being suitable for ring net cabinet, cable branch cabinet and distribution switching substation.
RLS-36 of an indoor high-voltage SF6 load switch and RLS-36 load switch plus fuse combination are complied with the standards of GB3804-1990, IEC60256-1,1997, GB16926, IEC60420 etc..
++++Service environment:
a) Air temperature Maximum temperature: +40ºC; Minimum temperature:-5ºC
b) Humidity Monthly average humidity 95%; Daily average humidity 90%.
c) Altitude above sea level Maximum installation altitude: 2500m
d) Ambient air not apparently polluted by corrosive and flammable gas, vapor etc.
e) No frequent violent shake
++++Main technical specifications:
Note: For short circuit breaking and peak current is based on Fuse plus combination.
