Sediver electrical HV laboratories

Evaluate the electrical performance of insulators is fundamental to assess the performance of any type of insulators, as well as string configuration.

The pollution performance of the insulator strings is critical for the choice of the most suitable insulator design for each customer specific environmental conditions.

Sediver Research Center experts benefit from 2 large testing facilities to perform electrical tests, to achieve optimum insulation for each specific environmental conditions.
