CSA MV-90 / MV-105 URD Cable | Medium Voltage Underground Residential Distribution Cable | 5-46 kV

Product Overview

This CSA MV-90/MV-105 URD Cable is a medium-voltage power cable engineered for Underground Residential Distribution (URD) and commercial power networks. Designed for reliable performance from 5 kV to 46 kV, it is suitable for direct burial, conduit, duct, and tray installations in wet or dry locations. Featuring Tree-Retardant XLPE (TR-XLPE) insulation and a copper concentric neutral, this cable is built for long-term durability and superior electrical performance in demanding underground and aerial environments.

Applications

  • Underground distribution of single or three-phase medium-voltage power.

  • Suitable for use in wet and dry locations, conduits, ducts, troughs, trays, and direct burial.

  • Sunlight-resistant for exposed outdoor applications.

  • Intended for continuous operation at conductor temperatures up to 90°C (MV-90) or 105°C (MV-105), with higher ratings for emergency overload and short-circuit conditions.

Standards & Certifications

This cable is designed and manufactured in compliance with the following key standards:

  • UL 1072 for Medium-Voltage Power Cables.

  • ICEA S-94-649 for Concentric Neutral Cables Rated 5 - 46 kV.

  • AEIC CS8 for Extruded Dielectric, Shielded Power Cables Rated 5 through 46 kV.

  • CSA C68.5 for Primary shielded and concentric neutral cable for distribution utilities.

Key Features & Specifications

    • Jacket: XLPE or PVC.

Cable Construction

The cable is constructed with the following layers for optimal performance and protection:

Layer Component Material / Description
1 Conductor Solid or Class B stranded aluminum or copper. Moisture block optional.
2 Conductor Screen Semi-conductive extruded layer.
3 Insulation Tree-Retardant Cross-linked Polyethylene (TR-XLPE).
4 Insulation Screen Semi-conductive, easily strippable extruded layer.
5 Neutral Helically applied, annealed, solid bare copper wires.
6 Outer Sheath Sun-resistant Linear Low Density Polyethylene (LLDPE), extruded to fill neutral wire spaces.
