The 25kV Concentric Neutral Cable, 100% Insulation Level (0.175"), Full Neutral, is a medium-voltage (MV) power cable designed for solidly grounded systems. It features a thermoset insulation system (typically XLPE or EPR), a helically applied full-sized bare copper concentric neutral, and an optional protective jacket.
Voltage Rating: 25,000 volts (25kV)
Insulation Level: 100% (for solidly grounded systems)
Insulation Thickness: 0.175 inch (4.45 mm)
Operating Temperature: 90°C continuous, 130°C emergency, 250°C short-circuit
Neutral Type: Full concentric neutral (equal to or greater than phase conductor ampacity)
Used in:
Utility and municipal underground power distribution
Interconnection of pad-mounted transformers, switchgear, and feeder circuits
Industrial plants, substations, and renewable energy applications (solar/wind)
Suitable for direct burial, duct/conduit, or tray installations
Applications requiring ground fault return path and electromagnetic shielding
