RLS series indoor high-voltage SF6 load break switch is the core matching component for 36 kV medium-voltage switchgear. SF6 gas acts as both arc-extinguishing and insulating medium. It adopts a standard three-position contact structure to realize Close, Open and Earth functions.
With compact overall dimensions, simple installation and operation, the product features strong environmental adaptability. Two types are available: standalone RLS load break switch and RLS switch-fuse combination unit. Both types realize control and protection for power supply equipment and transformer substations, and are widely applied to ring main units, cable branch cabinets and distribution switching stations.
This product complies with current domestic and international standards:
IEC 62271-103 (standalone load break switch), IEC 62271-105 (switch-fuse combination).
