145 - 420kV / 2000 - 3150 A
Type TPF pantograph disconnector is originally a design from Sprecher & Schuh AG. and has been produced in Norway since 1963.
EB Elektro has further developed the disconnector, among other things movable contact adapters with silver-plated copper bushings, which results in less corrosion and lower contact resistance.
The TPF pantograph disconnector has been supplied on a large scale to both the Norwegian and the international markets.
We can inspect and repair, as well as supply all spare parts to, disconnectors supplied from 1963 until today.
