Parallel Cables

Script: examples/parallel_cables.py

Three single-core 20 kV cables in flat formation, each carrying a different load profile. This example shows how mutual heating affects the temperature of parallel cables.

Setup

  • Cable: 1 × 240 mm2 Cu XLPE, 20 kV (three identical cables)

  • Formation: flat, 0.3 m centre-to-centre spacing at 1.0 m depth

  • Soil: wet soil (ρ = 0.7 K·m/W)

  • Ground temperature: Kasuda model (starting in July)

  • Loads:

    • Left cable: cyclic industrial (500/100 A, 8 h period, 60% duty)

    • Centre cable: constant 450 A

    • Right cable: residential daily pattern

What it demonstrates

  1. Adding multiple cables to a CableInstallation

  2. Using different LoadProfile types for each cable

  3. Mutual heating between parallel cables

  4. Comparing peak temperatures across cables

  5. Cross-section visualisation
