Can I cut and splice the pigtail cable in the field?

Yes, the pigtail cable can be cut to length and spliced. However, splicing underwater cables introduces a high risk of failure. We strongly recommend using a proper Subsea Splice Kit (epoxy or polyurethane potting) or ordering the cable pre-molded to the correct length from our factory via our Custom Engineering service.

Field splicing is the #1 cause of cable assembly failure.

  • Risk: A manual splice is rarely as robust as the factory High-Temperature Vulcanization bond.
  • Water Blocking: If you must splice, ensure you do not compromise the water-blocking gel/filler inside the cable.
  • Recommendation: Measure twice, order once. Let us manufacture the cable to your exact length (e.g., 5.5 meters) to avoid the need for splicing entirely.
