MV-90 / MV-105 URD Cable

Application & construction

5–46 kV URD cables (MV-90 / MV-105) are intended for use in dry or wet locations for distribution of single or three phase medium voltage power. Suited for use in wet and dry areas, conduits, ducts, troughs, trays, direct burial, sunlight, and where superior electrical properties are desired. These cables are capable of operating continuously at a conductor temperature not in excess of 90°C for normal operation, 130°C for emergency overload and 250°C for short circuit conditions.

Structure

1. Conductor — Solid or Class B compressed concentric lay stranded 1350 aluminum or copper conductors; conductor moisture block (optional)
2. Conductor screen — Semi-conductive extruded layer
3. Insulation — Tree-Retardant Cross-linked Polyethylene (TR-XLPE)
4. Insulation screen — Semi-conductive extruded layer, easy strippable
5. Neutral — Helically applied, annealed, solid bare copper wires
6. Outer sheath — Sun resistant Linear Low Density Polyethylene (LLDPE), extruded to fill spaces between neutral wires
