APPLICATIONS

Southwire CT3-13ET Type MV- 105 Cable is for use in aerial installations, direct buried, cable trays, troughs or raceway. These cables are capable of operating continuously at a maximum conductor temperature of 105°C for normal operation, 140°C for emergency overload conditions, and 250°C for short circuit conditions, and are rated at 15,000V, 133% insulation level (ungrounded system).

SPECIFICATIONS

 Southwire CT3-13ET Type MV-105 Cable is manufactured and tested in accordance with the latest revisions of the following standards and specification:

  • UL 1072 – Medium Voltage Power Cables.
  • ICEA S-93-639 (NEMA WC 74) – 5-46 kV Shielded Power Cable for Use in the Transmission & Distribution of Electric Energy.
  • ICEA S-97-682 (when requested) 5-46 kV Standard for Utility Shielded Power Cable.
  • UL 1685 – UL Flame Exposure Test.
  • IEEE 1202 – Flame Test (70,000 Btu/hr Vertical Tray Test)

Certified qualification tests were performed in accordance with the requirements of AEIC CS-8. Cable has fully met the qualification testing requirements of AEIC CS-8.

 

CONSTRUCTION

Southwire CT3-13ET Type MV-105 Cable offers heavy duty construction and flexible EPR insulation. For use in cable trays per NEC Article 392. Alternate constructions available. SOLONON™ low smoke, non halogen polyolefin jackets and CPE jackets are available upon request.

 

CT3-13ET 3c, 15kV, 220mil EPR(133%), TS, GW, PVC, CT Rated

Scope: This specification covers three conductor EPR (ethylene propylene rubber) insulated, shielded, thermoplastic jacketed power cables with grounding conductor for use in aerial installations, direct buried, cable trays, troughs, or raceways. These cables are capable of operating continuously at a temperature of 105°C for normal operations, 140°C for emergency overload conditions, and 250°C for short circuit conditions, and are rated at 15,000V, 133% insulation level (ungrounded system).

Standards: The following standards shall form part of this specification – UL Standard 1072 for Medium Voltage Power Cable and ICEA S-93-639 (NEMA WC 74) 5-46 kV Shielded Power Cable for Use in the Transmission & Distribution of Electric Energy.

Conductor: The conductor shall be Class B compressed concentric stranded bare copper in accordance with ASTM B3 and B8 and ICEA Part 2, Section 2.1 and 2.5.

 Conductor Shield: The conductor shall be shielded with an extruded semi-conducting thermosetting polymeric layer, which shall be firmly bonded to the insulation. The thickness shall be in accordance with the referenced standards.

Insulation: The insulation shall be EPR (ethylene propylene rubber) meeting the requirements of the referenced standards. The nominal thickness shall be 0.220″.

Insulation Shield: The insulation shall be shielded with an extruded semi-conducting thermosetting polymeric layer which shall be identified as semi-conducting. Over this layer shall be applied a helically wrapped 5-mil copper tape with 25% overlap. The method of phase identification will be similar to ICEA Method 3, using printed circuit numbers and colors (1-BLACK, 2-RED, 3-BLUE).

Grounding Conductor: The ground conductor shall be Class B compressed concentric stranded bare copper in accordance with ASTM B3 and B8.

Assembly: The insulated and shielded power conductors shall be cabled round with fillers and with a grounding conductor in one outer interstice and covered with a binder tape.

Jacket: The cable shall be covered with a black PVC jacket conforming to the requirements specified for polyvinyl chloride in ICEA. The average thickness shall be in accordance with the referenced standards. The jacket will be sunlight resistant and will meet the requirements of UL 1685 – UL Flame Exposure Test. Optional SOLONON low smoke, non halogen polyolefin jackets and CPE jackets are available upon request.

Tests: Qualification tests shall be conducted in accordance with the requirements of AEIC.
