Type SHD-CGC 5 kV Shielded Portable Mining Power Cable
Type SHD-CGC cable is a 5 kV, three-conductor shielded portable mining power cable with three grounding conductors and a centrally located ground-check conductor. It is intended for mobile mining equipment where a ground-check circuit and metallic insulation shielding are required.
- tension: 5 kV reference configuration
- Conducteurs de phase : stranded annealed tinned copper
- Isolation: EPR with semi-conducting conductor shield
- Insulation shield: non-conducting tape plus tinned copper/textile braid
- Ground-check: yellow-insulated tinned copper conductor in the cable centre
- Veste: reinforced extra-heavy-duty black CPE
- Références standard : ICEA S-75-381/NEMA WC 58, ASTM B172, ASTM B33 and CAN/CSA C22.2 No. 96

Type SHD-CGC 5 kV shielded portable mining power cable
TEBAOFLEX Type SHD-CGC cable is a three-conductor, shielded portable mining power cable for equipment that needs both a grounding system and a central ground-check conductor. The supplied 5 kV data set covers a heavy-duty EPR/CPE construction for mobile equipment circuits where a basic flexible feeder cable does not provide the required conductor arrangement or insulation shielding.
The practical buying question is not only conductor size. Confirm how the cable will move with the machine, whether the ground-check circuit is required at the termination, and whether the selected grounding-conductor size is compatible with the equipment and local mine rules. A cable that has the correct ampacity but the wrong check-ground layout can cause a costly field change before the machine enters service.
- Convient pour : mobile AC mining equipment requiring three phase conductors, grounding conductors, a ground-check conductor and metallic shielding.
- Reference range: Type SHD-CGC 3 × 2/0 AWG through 3 × 350 kcmil in the supplied 5 kV table.
- Confirmez avant de commander : equipment voltage, conductor size, route, bending duty, terminations, ground-check interface and required documentation.
- Choisissez une autre construction lorsque : the equipment does not require an individually shielded power construction or uses a different grounding/control-core arrangement.

Type SHD-CGC construction
The supplied Type SHD-CGC construction separates the three phase conductors from a central ground-check conductor and three grounding conductors. EPR insulation and a braided insulation shield are used inside a reinforced CPE outer jacket.
| Type SHD-CGC construction element | Construction fournie |
|---|---|
| conducteurs de phase | Stranded annealed tinned copper conductor |
| blindage conducteur | Semi-conducting layer |
| Isolation | Caoutchouc éthylène-propylène (EPR) |
| écran d'isolation | Non-conducting tape plus tinned copper/textile braid |
| conducteur de contrôle de mise à la terre | Tinned copper with yellow insulation, located in the centre of the cable |
| conducteurs de mise à la terre | Tinned copper conductors |
| Gaine extérieure | Reinforced extra-heavy-duty chlorinated polyethylene (CPE), black |
| Optional jacket materials | CSP, PCP, NBR or PVC available on request; a two-layer jacket with reinforcing fibre may be offered as an option |
Type SHD-CGC applications
Type SHD-CGC heavy-duty cable is intended for longwall shearers, continuous miners, loaders, drills, conveyors, pumps and other mobile equipment where grounding conductors, a ground-check conductor and metallic shielding are required. It is relevant to portable AC mining circuits where the cable must follow the movement of the equipment instead of remaining as a fixed building feeder.
Type SHD-CGC selection checks
- Confirm that the equipment termination accepts the central ground-check conductor and three grounding conductors.
- Match the phase size and supplied ampacity to the electrical design; account for route length and any project derating before final selection.
- Plan support, bend control, routing and strain relief around moving equipment. The supplied minimum bending radius is 6 × the finished cable outer diameter.
- Specify jacket option, cable length, marking, inspection and test documentation in the RFQ when the standard black CPE construction is not the final project requirement.
TEBAOFLEX can cross-check the existing cable marking and ground-check arrangement before quotation so a Type SHD-CGC request is matched to the machine connection rather than selected from phase conductor size alone.
