25kV SHD-GC Mining Cable
|
Features:
• Simultaneous extrusion and vulcanization of both strand shield and insulation form a virtually perfect electrode, eliminating unequal electrical stresses
• Excellent heat, moisture, steam, oil, corona, chemical and radiation resistance
• Flexible for easy handling
• High dielectric strength
• Electrical stability under stress
• Low dielectric loss
• Resists cutting, impact, abrasion, flame and sunlight
• Excellent thermal stability and physical properties over a broad temperature range
• Two-layer jacket is reinforced to provide maximum protection from mechanical damage—the cause of most portable cable failures
Product Construction
|
Conductor:
• 1 AWG thru 500 kcmil coated annealed copper, bunched wires, rope-lay stranded per ASTM B172
Extruded Strand Shield (ESS):
• Extruded thermosetting semiconducting stress control layer over conductor
Insulation:
• Ethylene Propylene Rubber (EPR) insulation colored for contrasting with black conducting layers
Insulation Shield:
• An extruded conduction layer covered by a conducting tape, and a flexible coated copper/textile braid shield overall provides greater mechanical protection than an equal thickness of insulation
Ground-Check Conductor:
• Annealed copper, rope-lay-stranded per ASTM B172, insulated with EPR and glassbraid
|
Grounding Conductor:
• Coated copper, rope-laystranded per ASTM B172
• Two conductors in contact with the flexible copper braid shield
Jacket:
• Reinforced, two-layer, extra heavy-duty, lead-cured Chlorinated • Polyethylene (CPE)
Jacket Marking:
• MINE CABLE SERVICES CORPORATION (SIZE), 3/C TYPE SHD-GC 25000 VOLTS (-50°C) FT1 FT5 CSA LR27161 P- 7K102-046 MSHA
Options:
• Colored jackets are available
• TPU (Thermoplastic Polyurethane) jacket
• Other jacket materials available upon request
Applications:
• Designed for use as a trailing cable on AC mining equipment:
• Where service conditions are severe and maximum safety is mandatory (such as power shovels and draglines in open-pit mines, quarries, gantry cranes and slag reclaiming)
• For high-voltage distribution in underground mines where frequent relocation is necessary
|
Compliances:
• ICEA S75-381 Portable and Power Feeder Cables for se in mines and similar applications
• Meets flame test requirements and is accepted for listing by MSHA
• Approved by the Pennsylvania Department of Environmental Protection
• Meets CAN/CSA-C22..2 No. 96 Portable Power Cables.
Packaging:
• Material cut to length and shipped on nonreturnable reels
