Multicore Copper Conductor PVC Insulation Mining Cable Ground-Check
1. Application:
Use in stationary, horizontal, HV mine power, distribution
circuits, for permanent
or semi-portable applications with power transmission in deep mines
,open pits,
tunnels, in conduit or duct, suitable for direct burial in wet or
dry locations.
2. Construction:
Conductors: bare, soft drawn, annealed copper per ASTM B-3, compact stranded
per ASTM B-496.
Strand shield: extruded semi-conducting compound.
Insulation: flame resistant (90℃) cross-linked polyethylene (XLPE) ICEA
S-75-381/NEMA WC-58.
Insulation shield: extruded semi-conducting compound. bare copper tape helically
applied.
Color code: Black, White, Red nylon tracer tape applied between the insulation
semi-conductive layer and the copper tape shield.
Ground wires: Uninsulated, soft drawn, annealed, compact stranded, bare copper
per ASTM B-496, B-8 and B-33.
Ground check: soft drawn, soft drawn, annealed, compact stranded, bare copper
with yellow EPR insulation.
Cabling: Three shielded conductors are assembled in a helical configuration
with two uninsulated ground wires, one yellow insulated ground
check and non-wicking fillers as needed .A woven nylon polyester
reinforcement binder is served over the entire assembly for
increased stability.
Reinforcement: A woven nylon polyester reinforcement binder is applied over the
completed assembly for added core stability.
Jacket: Black flame retardant (90℃) PVC per ICEA S-75-381/NEMA WC-58.
Available in optional colors .
