250 kcmil copper direct burial primary UD cable

250 kcmil copper medium voltage underground cable

25kV 133% I.L. – Maximum Insulation Protection for Critical 25kV Power Distribution Infrastructure
Critical power infrastructure at 25kV deserves more than just standard protection. This 25kV 133% insulation level primary underground distribution cable delivers extra dielectric strength with 320 mils of EPR insulation, providing a safety margin that standard 100% cables cannot match. The solid aluminum conductor offers efficient power transmission for long-distance feeders, while the concentric neutral ensures proper grounding and fault current management. UL1072 certified and MV-90 rated for continuous 90°C operation, this cable is designed for underground duct and direct burial installations in power generation facilities, utility substations, and large industrial plants. The rugged LLDPE jacket with three red stripes provides excellent resistance to moisture, abrasion, and environmental stress. The 133% insulation level provides enhanced protection against voltage surges, switching transients, and lightning strikes, making this cable ideal for critical infrastructure where power reliability is essential. Available with optional copper conductor, this is the preferred choice for engineers specifying maximum protection for mission-critical 25kV power distribution systems.
