Testing the high-voltage cables and the cables sheaths with 6,10,15,20 kW operating voltage and all types insulation such as XLPE and PILC.
Testing insulators and other electric equipment by high voltage power frequency AC.
Testing high-voltage switches’ vacuum chambers.
Laboratory and research works.
Features: The test system contains a few units, which are easy to carry and use. For example, only one high-voltage unit without the switching unit is needed for testing the transformer substations’ isolators.
