Specification

250 MCM 37 Stranded Copper Conductor 1/3 Neutral Shielded 345 Mils 100% XLPE 35KV MV105 Cable

Allowable Ampacity for 250 MCM 37 Stranded Copper Conductor 1/3 Neutral Shielded 345 Mils 100% XLPE 35KV MV105 Cable: 100 Amps

Also Known as:

MV105 Cable, CU Cable, XLPE Cable, Concentric Neutral Cable, Power Cable, Circuit Cable

Scope:

This specification describes copper, 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 and 140°C for emergency overload conditions. The overall cable is rated for 250°C for short circuit conditions per ICEA S-94-649, while the concentric neutral is rated for 350°C for short circuits per ICEA P-45-482. 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.

Applicable Standard:

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 3 – Standard Specification for Soft or Annealed Copper Wire
• ASTM B 5 – Standard Specification for High Conductivity Tough-Pitch Copper Refinery Shapes
• ASTM B 8 – Standard Specification Concentric Copper Conductors, Hard, Medium Hard, or Soft
• 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:

• Conductor maximum continuous temperature = 105°C
• Emergency temperature = 140°C
• Storing & working temperature range = -40…+105°C
• Installation & handling temperature = -10…+40°C
