Product Description
SC6 -12/24kV Type SF6 load break switch is developed by my Company which cooperated with foreign and nation High- medium voltage switchgear maker & design experts and research, laboratories. It adopt advanced design and manufacture experience, Its expanded with series type can is use for AC 50/60Hz, 12kV, 24kV power system for ingoing and outgoing line point switches. To protect and switching power & distribution transformers, capacitive bank, etc. With its Sf6 gas for insulation and arc suppressing technic and 3 position (Disconnect, earthing, closing).

Its indoor high-voltage SF6 load switch and 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.

All our Load break switch is complied with the standards of GB3804-1990, IEC60256-1997), GB16926, IEC60420, etc.
