Cable Test Set - KPG 110kV

The devices series KPG 50-120kV have been designed as Cable Test Sets for DC voltage testing of Medium Voltage Power Cables.

There are 4 different versions (50kV/80kV/110kV/120kV) available. The devices are characterized by low weight and high output power. Thanks to the compact 2-part design, the units are easily portable and perfect to be used on site. The separate design of Operation- and High Voltage unit, a key switch, switch-on interlock and a protective ground circuit ensure maximum safety.

Field of application

  • Testing of newly installed cables an cable joints before commissioning
  • Testing at re-commissioning of cable systems or High Voltage systems after maintenance and repair
  • Regular preventive cable testing
  • Testing of electrical equipment
