Cable Construction

Layer Material & Function
1. Conductor 3/0 AWG compressed stranded copper · Low impedance · High fault-current capacity
2. Conductor Shield Semi-conducting XLPE · Smooths electric field gradients
3. Insulation TR-XLPE · 133% insulation level · Superior dielectric strength
4. Insulation Shield Semi-conducting XLPE · Prevents partial discharge
5. Metallic Shield Helically applied copper wires · Manages ground-fault currents
6. Jacket LLDPE · UV/oil/chemical resistant · -40°C cold impact rating

Technical Advantages

  1. Enhanced Safety

    • 133% insulation level withstands 15kV surges + transient overvoltages.

  2. Environmental Resistance

    • LLDPE jacket resists moisture, acids, alkalis, and UV degradation.

  3. Fault Resilience

    • Copper wire shield handles 25kA fault currents (AEIC CS-8 compliant).

  4. Long Service Life

    • TR-XLPE insulation maintains integrity at 105°C for 40+ years.

  5. Easy Identification

    • Surface-printed jacket with lightning bolt symbol (red stripes optional).

Applications

  • Utility Primary Distribution: Underground feeder lines (≤15kV).

  • Industrial Complexes: Power networks in refineries, chemical plants.

  • Direct Burial: Conduit-free trench installations.

  • Solar/Wind Farms: Grid interconnection cables.

  • Flood-Prone Areas: Moisture-blocking design (ICEA T-31-610 compliant).

Engineering Selection Guide

  • For High-Corrosion Zones: Specify LLDPE jacket (superior to PVC in chemical resistance).

  • Fault-Prone Networks: Copper wire shield (not tape) for better current dissipation.

  • Cold Climates: -40°C rated sheath maintains flexibility in Arctic conditions.

  • Identification: Request red stripes for phase differentiation in duct banks.

Note: Custom configurations (neutral wires, armor, fire rating) available. Request ICEA test reports for water-blocking verification.
