Specification

500 MCM 37 Stranded Aluminum Conductor 1/2 Neutral Shielded 345 Mils 100% XLPE 35KV MV105 Cable

Allowable Ampacity for 500 MCM 37 Stranded Aluminum Conductor 1/2 Neutral Shielded 345 Mils 100% XLPE 35KV MV105 Cable: 100 Amps

Also Known as:

MV105 Cable, Neutral Power Cable, AL Cable, XLPE Cable, Direct Burial Cable, Concentric Neutral Cable

Scope:

This specification describes aluminum, concentric-neutral power-cable having Tree-Retardant CrossLinked Polyethylene (TR-XLPE) insulation and a Cross-Linked Polyethylene (XLPE) jacket. The cable is designed for use in three-phase systems with voltage not exceeding 35000 volts phase to phase and conductor temperatures not exceeding 105°C for normal operation, 140°C for emergency overload conditions, and 250°C for short circuit conditions. The cables are suitable for direct burial and installation in ducts.

Construction:

A “DISCHARGE-FREE” design concept underpins the manufacture of this cable. Conductor shield, insulation, and insulation shield are extruded simultaneously over the conductor by using tripleextrusion and dry-curing technology. The insulation shield is designed to be strippable.
Double-helix compatible water-blocking yarn is used on all conductors. Water-swellable tape is applied over the insulation shield.

Applicable Standards:

The cable produced under this specification will comply with all applicable requirements of the following standards, which are the principal standards of this product:

• ICEA S-94-649 – Standard for Concentric Neutral Cables Rated 5 through 46 KV
• AEIC CS8 – Specification for Extruded Dielectric, Shielded Power Cables Rated 5 through 46 KV
• UL1072 – MV90 and MV105 – Standard for Medium-Voltage Power Cables
• CSA 68.10 – Shielded Power Cable for Commercial and Industrial Applications, 5-46 KV

Cable components, raw materials, and testing procedures shall meet the requirements of publications referenced in relevant parts of the principal standards including, but not limited to

• ASTM B 231 – Standard Specification for Concentric-Lay-Stranded Aluminum 1350 Conductors
• ASTM B 3 – Standard Specification for Soft or Annealed Copper Wire
• ASTM B 5 – Standard Specification for High Conductivity Tough-Pitch Copper Refinery Shapes
• ICEA T-31-610 – Test Method for Conducting Longitudinal Water Penetration Resistance Tests

Testing:

Cable shall be tested as described in Parts 9 and 10 of ICEA S-94-649 and part G of AEIC CS8. Corresponding production tests shall be done in accordance with ICEA T-27-581, ICEA T-28-562, ICEA T24-380, and ICEA T-31-610. Factory test reports are available upon request.

Temperature Rating:
