Scope: This specification covers single conductor XLP (cross-linked thermosetting polyethylene) insulated, shielded, thermoplastic jacketed power cable for use in aerial, direct burial, conduit, and underground duct installations. 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 conditions, and 250°C for short circuit conditions, and are rated at 5,000 volts, 100% and 133% insulation level.
Standards: The following standards shall form a 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 specs 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 XLP meeting the requirements of the referenced standards. The nominal thickness shall be 0.090".
Insulation Shield: The insulation shall be shielded with an extruded semi-conducting thermosetting polymeric layer which shall be identified as semi-conducting. The thickness shall be in accordance with the referenced standards. Over this layer shall be applied a concentric serve of #24 AWG annealed solid bare copper wires over which shall be applied a lapped non-metallic tape.
Jacket: The cable shall be covered with a black sunlight resistant PVC jacket conforming to the requirements specified for polyvinyl chloride jackets in ICEA. The average thickness shall be in accordance with Table 7-3 of ICEA. Optional SOLONON low smoke, non halogen polyolefin jackets are available upon request.
Identification: Cable shall be identified by surface printing on the jacket.
Tests: Qualification tests shall be conducted in accordance with the requirements AEIC.
