POWER CABLES

Doble Lemke provides diagnostics and testings on-site or in the laboratory for:

 

  • Medium voltage cables
  • High voltage cables

 

A partial discharge measurement as an extended commissioning test ensures the quality of the installation work and cables from the beginning.

 

Critical regions in the cable can be located and identified. This allows the repairing and replacement of a section, which effects a significant cost reduction. 

Available Tests

  • Withstand voltage Test
  • Partial Discharge Test (EL)
  • DLA (TAN/PF, Watts, CAP)
  • Recovery Charge

Benefits

  • Ensuring the quality of the assembly work
  • Identification of weaknesses in the cable
  • Reduction of costs due to replacement of sections
  • High level of reliability
  • Extension of lifetime
