Neutral Sections and Phase Brakes

Neutral section and phase brakes separate different phase relations or different systems. High quality materials and replaceable insulator rods give a long lifespan with low LCC for speeds up to 200km/h with braking loads up to 120kN.


Surge Arresters

Surge arresters for medium voltage and high voltage systems, ·IEC line discharge, class 1- 4, Polymeric and porcelain constructions suitable for voltages from 3KV to 330KV using the latest ZnO technology.

Tension Balance Weights.png

Tension Balance Weights

Constant tension catenary system allowing for any movement due to expansion or contraction of the wire.
