The Medium Voltage Primary Underground Distribution (UD) cables consist of a Copper (filled or unfilled) conductor, covered with ethylene propylene rubber (EPR), a concentric neutral of helically applied copper wires, and a linear low-density polyethylene (LLDPE) jacket with 3 extruded red stripes.
Features:
• High dielectric strength
• Low moisture absorption
• Low dielectric loss
• Excellent resistance to treeing
• Jacket is sunlight-resistant
• Designed to operate continuously at a conductor temperature
not exceeding
•105°C for normal operations
• 140°C for emergency overload
• 250°C for short circuit
Specifications:
