A safety device at the heart of each substation.

The HV disconnector is the ultimate substation device for the protection of personnel and equipment.
When it is open, it features the highest insulation capability and, in closed position, the ability to transfer any current likely to transit through the lines or busbars.
Its versatility and performances make it a must-have for an optimised substation management.

As specialists, Coelme and Egic have been dedicated to this activity since the early 1950’s, leading to an unrivalled experience of the needs of contractors and final users, worldwide.
We propose an extensive range of switches, from 36 kV to 800 kV, and from 1250 up to 6300 A.

We are able to offer a product for every possible application including those where harsh environments, extreme climatic conditions, seismic withstand capability and mechanical integrity demand products of the highest possible performance and quality.

To describe accurately each reference in our wide range of disconnectors, we have now improved our designation system. This allows to understand at once the characteristics of the desired equipment. Full explanation is available here.
