Product Description

 GIS MV cubicles SF6 LBS

 
Specification:            

Load break switch+fuse combination set
Load break switch top unit
Load break switch lower unit
GSC-12/24/36kV serie is 3 position SF6 load break switch designed for indoor and outdoor medium voltage switchgear-air insulated panel,adopted SF6 gas as arc-extinguishing and insulation medium, The epoxy resin enclosure ensures good insulation and resistance to moisture and environmental pollution.

characteristics :
Strictly follow the standards of IEC60256-1, IEC60420,GB3804-1990,1997, GB16926,etc....
Small volume ,easy installation and operation
Great adaptability to surrounding environment,suitable for high altitude.
