The 15kV Concentric Neutral Cable (100% Insulation Level - 0.175") with Full Neutral is a medium-voltage power cable designed for grounded systems. It features a thermoset insulation (XLPE or EPR), a bonded conductor shield, a semi-conductive insulation shield, and a helically wound full-size bare copper concentric neutral with an optional outer jacket.
Voltage Rating: 15,000 Volts (15kV)
Insulation Level: 100% (for solidly grounded systems)
Insulation Thickness: 0.175 inch (4.45 mm)
Neutral Configuration: Full-size concentric neutral (equal to conductor ampacity)
Temperature Rating: 90°C (normal), 130°C (emergency), 250°C (short circuit)
This cable is widely used for:
Primary distribution systems in utilities and municipalities
Underground feeder cables for pad-mounted transformers, switchgear, and substations
Industrial plant power distribution
Renewable energy interconnection (solar farms, wind projects)
Installations in ducts, conduit, or direct burial
The full-size neutral ensures fault current return, shielding, and voltage balance in grounded systems.

100% insulation level is for solidly grounded systems only.
For ungrounded or impedance-grounded systems, use 133% insulation level (≈ 0.220").
Full concentric neutral is critical for:
Ground fault return path
Proper shielding and voltage control
System grounding reliability
