Medium Voltage Indoor Applications
Our medium voltage arresters are used for protection of medium voltage networks and devices against overvoltage caused by lightning and switching surges.
Specially developed indoor medium voltage arresters are particularly suitable for the protection of transformers, switchgear and cable terminations in closed spaces.
These arresters are available with different connectors and can be customized to adjust to a given space.
Surge arresters with silicone insulated cable for connection to SF6 facilities are also available on request.
We look forward to your request!
