Key Features
- The three-pole SF₆-insulated load-break switch is a self-contained, enclosed equipment assembly featuring double rotary contacts and arc quenching in an SF₆ insulating medium.
- The main component is the load-break switch itself, with or without an earthing switch, designed to interrupt rated load currents on overhead lines in electricity distribution networks.
- Because the switch components are enclosed and operate in an SF₆ gas-insulated environment, the equipment is durable and reliable. The internal components are not directly exposed to rain, snow, wind, pollution or the effects of bird activity.
- The electrical cabinet provides control and monitoring of the switch-disconnector’s three-pole outdoor switching module.
- The cabinet contains the protection, control and signalling components, together with the electrical, electronic, telecommunications and software subsystems required for the remote control and remote monitoring of the load-break switch.
