Mobile disconnector

Mobile disconnector

Equipment with an insulating structure and remote control that enables the disconnection and connection of TPCs (Capacitive Potential Transformers) and PRs (Lightning Rods) on busbars and terminals of energized transmission lines in substations from 69 to 500kV, which, combined with live line techniques, allows maintenance or replacement of the equipment without the need to disconnect the circuits.

Developed to facilitate assembly in the field by live line crews, while maintaining the routine use of insulating scaffolding and its safety distances.

For use, an insulated modular scaffold is required, which must be purchased separately.
