  • HV EHV Cable Jointing & Installation Services
  • Jointing and terminating cable - LV MV HV EHV 
  • Extensive range of testing services covering all cable systems including up to 200kV DC and AC VLF cable sheath testing
  • De-oiling of redundant ­fluid filled cable networks from cables to all ancillary equipment
  • Cable system excavation and all aspects of installation including cable management
  • Substation installation including plinths, transformers, switchgear and earthing

High Voltage Cable Testing - HVA200

High Voltage Cable Testing - HVA200

Their extensive HV-EHV cable testing ranges and equipment includes the HVA200 - Wootton & Wootton are the first company to have one in commercial use in the UK.

  • First unit in commercial use in the UK
  • Sinusoidal VLF output voltage up to 200kV (141kV rms)
  • DC (+/-) voltages up to 200kV
  • Partial Discharge & Tan Delta diagnostics available
  • Smallest and lightest AC test set for cables up to 132kV globally
  • Compact design allowing easier access to cable test locations
  • True continuous overvoltage withstand test

Read how the HVA200 provided 33kV subsea pressure testing for WPD enabling switchgear testing and power restoration of 33kV medium voltage cable supplying the Isles of Scilly.

PD measurements comparable to 50 Hz measurements and better sensitivity on TD measurements than 50 Hz testing.
