How do we ensure the quality and integrity of 220 kV cable joints and terminations?

2025-08-14

Jointing and termination are the weakest points of an EHV cable system, requiring an uncompromising focus on quality.

  • Highly Skilled Technicians: Only certified and extensively trained jointing technicians with specific experience in 220 kV systems are permitted to perform these tasks.

  • Cleanliness and Environment: The work is performed in a completely clean, dust-free, and moisture-controlled environment using specialized tents or shelters.

  • High-Quality Kits: We use only pre-tested and type-approved jointing and termination kits from leading manufacturers to guarantee reliability.

  • Shielding and Grounding: The integrity of the cable's shielding and grounding is meticulously re-established at every joint and termination point to manage electrical stress and prevent partial discharge.
