What Is SHD-GC Cable?
SHD-GC cable, also called Type SHD-GC mining cable, is a shielded heavy-duty trailing cable for mobile mining equipment that requires power conductors, grounding conductors and a dedicated ground-check conductor. The ground-check conductor works with a compatible monitoring system to supervise the grounding path; it does not replace the mine’s complete protection and inspection program. Available project configurations include 2 kV, 5 kV, 8 kV, 15 kV and 25 kV. Typical applications include continuous miners, longwall systems, electric mining shovels, draglines and mobile drills.
Selection starts with the operating voltage, load current, conductor size, ground and ground-check arrangement, movement method, route geometry, mechanical exposure, ambient conditions and required approvals. This portable mining power cable should not be selected by voltage alone because insulation thickness, shielding, jacket construction, finished diameter, bend radius and ampacity change with the confirmed design.

TECHNICAL FOCUS
Typical SHD-GC Cable Construction
First, engineers define SHD-GC construction around the requested voltage, power-conductor sizes, grounding arrangement, ground-check circuit and mechanical service conditions. They then identify the insulation system, shielding method, ground conductors, ground-check conductor, any fillers or reinforcement, and outer jacket for the approved design.
CONSTRUCTION DIFFERENTIATION
Construction by Voltage Class
Type SHD-GC is not one identical construction across every voltage class. Shielding layers, insulation thickness, ground-check size, jacket thickness and finished dimensions change with the selected voltage and conductor size.
| Construction item | 2 kV supplied reference | 5 kV to 25 kV supplied reference |
|---|---|---|
| Power conductors | Flexible stranded annealed tinned copper | Flexible stranded annealed tinned copper |
| Conductor shield | Confirm against the approved order construction | Semi-conducting layer referenced for the supplied construction |
| Insulation | EPR | EPR |
| Insulation shield | Tinned copper/textile braid reference | Non-conducting tape plus tinned copper/textile braid reference |
| Ground-check conductor | Tinned copper with yellow polypropylene insulation | Tinned copper with yellow polypropylene insulation |
| Ground conductors | Tinned copper grounding conductors | Tinned copper grounding conductors |
| Outer jacket | CPE or TPU option according to approved construction | Reinforced heavy-duty CPE or TPU option according to approved construction |
JACKET SELECTION
Jacket Selection: CPE vs TPU
Jacket selection depends on dragging, flexing, reel and sheave conditions, oil or chemical exposure, temperature, moisture, abrasion and impact. Confirm the material in the approved order drawing.

KEY DIFFERENTIATOR
Ground-Check Conductor for Ground-Continuity Monitoring
GC in SHD-GC means ground check. In a compatible mine electrical protection system, the insulated ground-check conductor helps the monitoring circuit supervise the grounding path to mobile equipment. Therefore, it distinguishes SHD-GC selection from shielded heavy-duty power construction without a ground-check conductor.
However, the ground-check conductor does not replace the complete site protection, grounding and inspection program. Before ordering, confirm the circuit arrangement, conductor size, terminations and project approval requirements against the equipment and mine electrical specification.

RFQ CHECKLIST
How to Specify SHD-GC Cable for a Quote
Accurate SHD-GC cable selection starts with the electrical system and the actual cable route. Include the following information so the construction, cable size and project documentation can be reviewed together.
| Information to provide | Why it matters |
|---|---|
| Voltage class | Confirm 2 kV, 5 kV, 8 kV, 15 kV or 25 kV before selecting insulation and shielding construction. |
| Power conductor size | Provide AWG or kcmil size, required ampacity and circuit length for electrical review. |
| Grounding and ground-check arrangement | Confirm conductor sizes, monitoring-system compatibility and termination requirements. |
| Mining equipment | Identify the continuous miner, longwall machine, shovel, dragline, drill or other powered equipment. |
| Cable movement and route | Describe trailing, reeling, sheave, roller, dragging and bend-radius conditions. |
| Operating environment | State ambient temperature and exposure to abrasion, impact, oil, water or chemicals. |
| Compliance and delivery | List applicable ICEA, NEMA, MSHA or project requirements, together with cable length, quantity and drum format. |
INSTALLATION GUIDANCE
Installation Limits and Handling
| Engineering reference | Selection guidance |
|---|---|
| Maximum continuous conductor temperature | 90°C in the supplied construction references. |
| Minimum bending radius | 6 × finished overall cable diameter. Confirm moving route, reel, sheave and roller design separately. |
| Ampacity | Use the voltage-class table as a reference only; apply installation and environmental derating before final selection. |
| Ground-check circuit | Confirm monitor compatibility, terminations and protective relay logic as one system with the cable design. |
| Final construction | Verify conductor size, shield arrangement, jacket material, outside diameter, weight and marking against the approved technical data sheet. |
Do not select a portable mining cable by voltage or conductor size alone. Installation method, reel layers, route length, movement duty, mechanical exposure, ambient temperature and termination design affect the finished selection.
SHD vs SHD-GC Cable: What Is the Difference?
| SHD | SHD-GC |
|---|---|
| Shielded heavy-duty cable construction | Shielded heavy-duty construction with ground-check conductors |
| Selected around power and shielding requirements | Selection also considers compatible ground-continuity monitoring |
| Exact construction follows the project specification | Ground-check circuit arrangement requires project confirmation |
Choose SHD-GC when the mining power system requires a compatible ground-check circuit. Terminology and construction should always be confirmed against the applicable project specification.
TYPICAL EQUIPMENT
Mining Applications
First, engineers select Type SHD-GC cable for mobile mining equipment that needs flexible, shielded power together with a project-defined ground-continuity monitoring circuit. They then review the cable construction against equipment duty, travel path, reel or roller arrangement, ambient conditions and applicable project requirements.
| Equipment | Typical SHD-GC Cable Role |
|---|---|
| Longwall shearer | Flexible shielded trailing power for continuous underground movement and cable handling. |
| Continuous miner | Heavy-duty mobile power where the equipment protection system requires a compatible ground-check circuit. |
| Mining shovel or excavator | Medium-voltage flexible power for severe mechanical duty, route movement and outdoor exposure. |
| Dragline | Rugged trailing power for large mobile mining machinery, subject to the confirmed cable-management design. |
| Rotary blasthole drill | Flexible shielded power for mobile mine drilling systems and repeated positioning. |
| Dredger | Heavy-duty flexible power for demanding dredging equipment after route and environmental review. |
For surface mines, teams can review configurations for electrically driven shovels, excavators, draglines, rotary drills, crushers and mobile substations. Meanwhile, underground projects often involve continuous miners, longwall equipment, shuttle-car supply systems, roadheaders and face drills. The ground-check conductor supports the compatible monitoring circuit; however, mine operators must still apply the complete electrical protection and inspection program for the site and equipment.
For quotation, provide the equipment type, operating voltage, conductor size, route length, reel or sheave details, travel frequency, ambient temperature, exposure to oil or water, and required approvals. This allows the voltage class, grounding arrangement, jacket option, drum length and technical documentation to be reviewed against the actual duty.

Frequently Asked Questions
What is SHD-GC cable?
SHD-GC is a shielded heavy-duty mining trailing cable that combines three power conductors, grounding conductors and an insulated ground-check conductor in a project-specific construction. It is used for compatible mobile mining power systems where shielding, mechanical protection and ground-continuity monitoring are required.
What does GC mean in SHD-GC?
GC means ground check. The insulated ground-check conductor forms part of a compatible monitoring circuit that supervises continuity of the equipment grounding path. Cable configuration, terminations, monitoring equipment and protective logic must be confirmed together for the mining power system.
What is the difference between SHD and SHD-GC cable?
Both types use a shielded heavy-duty construction, but SHD-GC adds a dedicated ground-check conductor for compatible ground-continuity monitoring. Choose between SHD and SHD-GC from the equipment protection design and applicable project specification rather than treating the names as interchangeable.
What voltage ratings are available?
Project configurations are available for 2 kV, 5 kV, 8 kV, 15 kV and 25 kV systems. Each voltage class can require different insulation thickness, shielding, jacket thickness and finished dimensions, so the approved data sheet must identify the ordered construction.
Is SHD-GC suitable for underground mining?
SHD-GC cable can be specified for underground mining equipment when the voltage, movement route, mechanical duty, ground-check system, flame or environmental requirements and applicable approvals are confirmed for the project. Suitability is determined from the complete installation, not the cable name alone.
What is the minimum bending radius?
The current supplied construction reference uses 6 × the finished cable outside diameter. Reeling, sheave, roller and moving-route conditions require a separate review because repeated dynamic bending can need a different cable-management limit.
Can TEBAOFLEX customize SHD-GC cable?
Yes. TEBAOFLEX can review the voltage class, AWG or kcmil conductor size, grounding and ground-check arrangement, CPE or TPU jacket, printed marking, drum length, packing and required project documentation before issuing the production specification.
