Product overview

SHD-GC Cable for 2kV to 25kV Mining Power

SHD-GC cable is a shielded round portable mining power cable for mobile and semi-mobile equipment that needs power conductors, grounding conductors and a ground-check conductor in one heavy-duty construction. TEBAOFLEX supplies the product family for 2kV, 5kV, 8kV, 15kV and 25kV duties. Cable schedules may also write the name as SHD GC cable, Type SHD-GC, SHD-GC mining cable or cable SHD-GC.

The 2kV construction covers shielded portable power requirements that should not be selected only by comparison with Type G-GC or Type W. Higher-voltage configurations serve demanding mining equipment where shielding, grounding continuity, mechanical protection and a rugged jacket are central to the specification. The supplied technical data covers 6 AWG to 500 kcmil at 2kV and 5kV, 4 AWG to 500 kcmil at 8kV, 2 AWG to 4/0 AWG at 15kV, and 1 AWG to 4/0 AWG at 25kV.

Typical construction uses flexible tinned-copper conductors, EPR insulation, conductor and insulation shielding, grounding conductors, an insulated ground-check conductor and an extra-heavy-duty jacket. CPE and TPU jacket options can be reviewed against abrasion, impact, oil, weather, water and low-temperature exposure.

Use this page as the consolidated SHD GC cable specs and quotation reference. Before ordering, confirm system voltage, conductor size, cable length, equipment, route movement, bend radius, jacket exposure and required approval documentation. Compare the Mining & Tunneling Cables range or use the SHD-GC vs Type G-GC vs Type W guide when the cable type is not yet fixed.

Construction

SHD-GC Cable Construction

The exact layer thicknesses and conductor sizes change with voltage and cable size. The following construction describes the consolidated 2kV to 25kV product family and should be checked against the project cable schedule.

Layer	Typical construction	Selection purpose
Power conductors	Annealed, flexible stranded tinned copper	Supports repeated handling and corrosion resistance.
Conductor shield	Semi-conductive layer over each power conductor	Controls the electrical field at the conductor interface.
Insulation	Ethylene-propylene rubber (EPR), typically rated for 90°C conductor operation	Provides dielectric performance with flexibility.
Insulation shield	Semi-conducting layer with composite tinned-copper/polyamide braid; coverage follows the selected design	Provides shielding while retaining portable-cable flexibility.
Grounding conductors	Flexible tinned-copper grounding conductors laid in the interstices	Provides the equipment grounding path required by the circuit design.
Ground-check conductor	Yellow TPE-E or polypropylene insulated flexible tinned copper	Supports ground-continuity monitoring; size is project dependent.
Core assembly	Fillers and binder/separator tape as required by the construction	Maintains a round profile and stable core lay.
Outer jacket	Extra-heavy-duty CPE or project-specified TPU; two-layer or reinforced options available	Selected for abrasion, impact, oil, weather, water, torsion and temperature exposure.

Construction note: jacket compound, reinforcement, shield coverage, ground-check size and approval markings must be confirmed for the exact voltage, conductor size and order.

Applications

SHD-GC Mining Cable Applications

Type SHD-GC is selected when the route needs a shielded portable cable with grounding and ground-check continuity. Match the voltage and mechanical duty to the machine rather than treating every mining cable name as interchangeable.

Equipment or route	Typical selection focus	Important checks
Continuous miners and longwall systems	2kV or project-specified shielded portable power	Route movement, ground-check circuit, water, abrasion and cable handling.
Loaders, drills, jumbos and conveyors	Flexible trailing duty with repeated handling	Voltage, bend radius, pulling tension, run-over risk and jacket compound.
Shovels, draglines and dredges	Higher-voltage heavy mobile mining power	8kV, 15kV or 25kV class, conductor size, route length and mechanical protection.
Pumps and temporary mine distribution	Shielded portable or semi-mobile power	Water exposure, installation method, voltage drop and termination system.
Cranes and shore-to-ship routes	Project-specific flexible heavy-duty supply	Reeling or suspended movement, torsion, travel speed and local rules.

Selection boundaries

Do not substitute Type G-GC or Type W solely because the voltage is 2kV; first confirm whether the circuit requires a shielded SHD-GC construction.
Do not treat a standard bend-radius value as a drum-design approval. Send reel, sheave, roller and route data for moving systems.
MSHA, CSA or other approval language applies only when the exact supplied construction and marking are documented for the order.

For a broader application path, review Mining Cable Solutions. For a cable-family comparison, use the SHD-GC, Type G-GC and Type W guide.
