High Voltage Cable Checklist

  1. Correct cable type as per electrical cable schedule and drawings.
  2. Confirm cable and core markers are correct at each end, and at transits (if applicable).
  3. Ensure there is no visible damage and clamping/cleating cable support correct as per project specification.
  4. Bending radius and stretch prevention according to specification and no stress on gland.
  5. Cable glands are the correct type and size as per cable schedule and installed according to specification.
  6. Confirm earth bonding is correct to design specification.
  7. Ensure gland plates for single core cables are non-magnetic.
  8. Ensure single core power cables installed in fault rated trefoil cleats.
  9. Ensure mechanical cable protection correct.
  10. Ensure the correct size of crimped connector has been used.
  11. Check terminations and earth connections are tight and correct.
  12. Check that phase identification is correct.
  13. Ensure torqueing of split, bolted connections correct. Check after insulation resistance (IR) and pressure test.
  14. HV cable kits correctly installed, stress relieved and earthed.
  15. Confirm continuity on all cores and screens.
  16. Carry out IR and High Voltage Pressure Test as per manufacturer’s specifications on all cores and record results.
  17. Reconnect cable cores and confirm correct terminations and phase rotation.
  18. Record torque settings and bolt size.
  19. Gland body to earth path resistance (Max 0.1Ω). (__________Ω)
  20. Confirm protective measures (i.e. kick plates) are fitted correctly.
  21. Replace covers and check all bolts are correct and none missing.
  22. Installation drawings have been “Red Lined” as per the project completions procedure.
