Product Overview

The RLS-36 is a 36kV/40.5kV SF6 gas-insulated load break switch designed for indoor medium-voltage applications. Utilizing SF6 gas for superior arc quenching and insulation, it features a three-position switching mechanism (ON-OFF-GROUND) in a compact, space-saving design. The RLS-36 and its fused combination variant provide reliable protection and control for power distribution networks, particularly in ring main units (RMUs), cable branch cabinets, and distribution substations.

Compliant with GB3804-1990, IEC60256-1:1997, GB16926, and IEC60420, this switchgear ensures safe and efficient operation in diverse electrical environments.
