ProductICEA S-75-381
Applications
Extra-heavy-duty trailing cable designed for used in mining machines, dredges, sholves, and similar mobile equipment, also suitable to be used with stationary equipment or medium voltage distribution in mines where higher flexibility is desired.
Construction: Multiconductor with three individually shielded power conductors, two grounding conductors, and one ground-check conductor.
1. Conductor: Very flexible stranded copper conductors.
2. Conductor shield: Conducting stress control material.
3. Insulation: Ethylene Propylene Rubber (EPR).
4. Insulation shield: Conducting material.
5. Metallic shield: Composite tinned copper/fiber braid.
6. Grounding conductors: Two flexible stranded bare copper conductors.
7. POWERMINE® Super Pilot: one highly flexible conductor, insulated with EPDM with excellent insulation resistance properties and highly reinforced thanks to the incorporation of aramid yarns in the conductor.
8. Reinforcement: Fabric tape and double synthetic servings applied over the cores asembly.
9. Jacket: Extra-heavy-duty Thermoplastic Polyurethane (TPU). Colour upon request.
Marking: NEXANS CHILE POWERMINE SHD-GC-EU "size" "voltage" "date"
Alternative with chlorinated polyethylene (CPE): POWERMINE® SHD-GC-CP

CURRENT CARRYNG CAPACITY FOR MINE TRAILING CABLES
The recommended ampacities are based on an ambiet temperature of 40°C (104°F) in air according to ICEA S-75-381, Annex H. Correction factors for ampacities at various ambient temperatures are as follows:
CURRENT CARRYNG CAPACITY FOR MINE TRAILING CABLES
NOTES
When the cables are used with one or more layers wound on a reel, the ampacities shal be corrected according to the amount of layers and reel type. For further details, see the technical guide: "Ampacity derating factors for mine trailing cables coiled on reels".
Values not defined as "maximum", "max.", "minimum" or "min." are not normative requirements in the standard and they are indicative only.
