SHD-CGC FOM 5 kV Mining Power Cable with Multimode Fibres

SHD-CGC FOM mining cable combines a 5 kV power circuit with multimode optical communication in one portable cable. Three individually screened phase cores supply the load, while two bare earth conductors and a separate insulated ground-check conductor provide distinct connections for the equipment grounding and monitoring circuits. The optical module occupies an interstitial position beside the power cores; the ground-check conductor remains at the centre.

Start the selection with the complete circuit arrangement. A six-fibre optical module and a twelve-fibre module give different termination requirements, and the 50/125 µm or 62.5/125 µm fibre choice must match the optical equipment. Keep the fibre count, fibre type and ground-check details on the order together with the power-conductor size. The listed 5 kV reference series spans 6 AWG to 500 kcmil, with separate grounding sizes and mechanical data for each row.

Choose the jacket and cable route as one system. The black polychloroprene construction and optional TPU jacket need to be matched to the movement, minimum temperature, pulling arrangement and termination hardware. A shared reference diameter is not a substitute for checking the final optical configuration and connector entry. For a different circuit arrangement, compare the related power-and-fibre constructions before ordering. TEBAOFLEX supplies this family from a 50 m minimum order, with a lead time of 7–45 working days.

Construction

SHD-CGC FOM keeps the optical unit, protective-earth conductors and central ground-check core electrically and physically distinct. Each power core has its own conductor screen, EPR insulation and composite metallic/textile braid.

Applications

Use the combined power-and-optical construction where a mine-equipment route needs both the electrical supply and a fibre link. Select the movement duty and end connections for the complete assembly.

• Portable mining power routes with a 5 kV supply and an optical communication requirement.
• Quarry and shaft-sinking equipment connections that require separate earth and ground-check circuits.
• Heavy industrial routes subject to abrasion, impact, oil and weather exposure, with the jacket chosen for the installation.
• Replacement enquiries where the existing power size, two-earth arrangement, central ground check and multimode fibre interface can be matched individually.
• Reel, guide and support arrangements reviewed together with the 8 × diameter minimum bend radius, cable weight and tensile-force limit. Specify reverse bending and movement conditions separately.

For route and construction selection, see the medium-voltage mining cable selection guide.

For a 5 kV central-ground-check cable without this optical arrangement, compare Type SHD-CGC mining cable. Its grounding layout and dimensions must be checked independently.

Where the optical system requires single-mode fibres, review the 5 kV-class PCBU-GC-FO construction with 24 single-mode fibres or SHD-GC-FO 35 kV cable with 12 single-mode fibres. These are different voltage or circuit constructions; fibre count alone does not establish interchangeability.

Specifications

G means each of the two protective-earth conductors. GC means the separate central insulated ground-check conductor. Specify its conductor size and termination alongside the optical unit on the quotation and cable drawing.

The dimensional series is a nominal family reference. Select the exact 6- or 12-fibre unit, fibre geometry and jacket material before confirming the outside diameter, mass, connector entry and drum capacity.

The two mass columns retain their independently stated reference values. Use the quoted mass for drum, handling and support calculations; do not recalculate one column to replace the other.

Resistance is stated at 25°C, not 20°C. Inductance and capacitance use 1000 ft length units; 1 kcmil and the historical designation MCM represent the same conductor-area unit.

Reference ampacity uses continuous operation at 90°C conductor temperature and 40°C ambient. Apply installation and thermal corrections, including any cable remaining on a reel.

Calculate bending clearance from the final cable diameter. Evaluate the stated tensile-force limit together with the route, acceleration, guides and terminations; it does not define an unrestricted unsupported shaft length.

Specify minimum ambient temperature and whether the cable is moving, installed or being handled. Tie the agreed low-temperature performance to the selected polychloroprene or TPU jacket construction.

Select the fibre interface, link length and optical performance requirements together. A fibre core/cladding size alone does not define an OM grade, bandwidth, attenuation limit or connector system.

Standards

Official standards and approval references

The current NEMA/ICEA publication uses WC 23058 in place of the historical WC 58 designation. State the required edition with the voltage, conductor arrangement, jacket and optical configuration in the order specification.

• ANSI/NEMA WC 23058 / ICEA S-75-381 — Current portable and power-feeder cable standard for mines and similar applications.
• ASTM B172 — Rope-lay stranded copper conductors — Official conductor-standard record covering rope-lay conductors with bunch-stranded members, including tin-coated copper wire.

Certifications and document support

Review our company certificates and document scopes when identifying the documentation required for the quoted construction.

Provide the destination mine, approval body, required cable marking and complete power/earth/ground-check/fibre construction for document review. Where an order requires MSHA identification, match the approval number and permitted marking to the selected cable type, voltage and size. Optical performance and termination records should identify the ordered fibre unit.
