How do you manage heat dissipation and thermal issues for 132 kV underground cables?

2025-08-14

Efficient heat dissipation is crucial for the performance and longevity of 132 kV underground cables. The insulation and surrounding environment play a key role. Our solutions and best practices address this through:

  • Cable Design: Utilizing XLPE insulated cables with specific designs to handle thermal stress.

  • Bedding Material: Surrounding the cable with a thermal backfill material, such as specific sands, to conduct heat away from the cable.

  • Installation Depth: Laying the cables at a sufficient depth to take advantage of the ground's natural cooling properties.

  • Trefoil Formation: Arranging the single-core cables in a trefoil formation to optimize heat dissipation and minimize electromagnetic interference.
