When underground and surface mining operations demand high-voltage power, extreme mechanical strength, and uncompromising safety, the Type SHD-GC Heavy Duty Cable stands out as a proven solution. Designed in accordance with ICEA S-75-381, this 15 kV three-conductor round portable power cable with a reinforced CPE jacket is widely used on longwall shearers, continuous miners, and heavy mobile equipment.
But what exactly makes a Type SHD-GC cable different, and how do you know if it’s the right choice for your mining operation—especially in demanding environments?
What Is a Type SHD-GC Heavy Duty Cable According to ICEA S-75-381?
A Type SHD-GC cable is a shielded, heavy-duty portable mining power cable specifically engineered for medium-voltage applications up to 15 kV. The designation typically indicates:
SHD – Shielded Heavy Duty
GC – Includes both grounding conductor and ground-check conductor
Under ICEA S-75-381 / NEMA WC 58, SHD-GC cables are intended for portable power distribution where cables are frequently dragged, bent, reeled, or exposed to impact, abrasion, moisture, oil, and chemicals.
Where Are Type SHD-GC 15 kV Heavy Duty Cables Commonly Used?
Which Mining Equipment Requires SHD-GC Cables?
Longwall shearers
Continuous miners
High-power mobile shovels
Dredges and drills
Large underground mobile substations
How Does SHD-GC Compare with Other Mining Cable Types?
Feature | SHD-GC | SHD-G | Type G-GC |
|---|---|---|---|
Voltage rating | Up to 15 kV | Typically ≤ 8 kV | ≤ 5 kV |
Insulation | EPR | EPR | EPR/PVC |
Shielding | Full | Partial | Limited |
Ground-check | Yes | Optional | Yes |
Typical use | Heavy MV mining | Medium duty | Light to medium duty |
Conclusion:
For high-voltage, safety-critical mining applications, SHD-GC is the preferred choice.
What Are Best Practices for Installing SHD-GC Heavy Duty Cables?
Respect the minimum bending radius (8×OD)
Avoid sharp edges and pinch points
Use proper cable handling equipment for heavy weights
Ensure ground-check continuity testing before energising
Follow mine-specific safety and lock-out procedures
Correct installation directly impacts service life and operational safety.
Frequently Asked Questions (FAQ)
Can Type SHD-GC cables be used above ground?
Yes. While designed for underground mining, they are also suitable for harsh surface applications involving mobile equipment.
Is a CPE jacket better than PVC for mining?
Absolutely. CPE offers superior resistance to oils, chemicals, abrasion, and flame spread.
Can jacket materials be customised?
Yes. Options such as CSP, PCP, NBR, PVC, TPU, or dual-layer reinforced jackets are available on request.
Why is a ground-check conductor mandatory in many mines?
It ensures grounding integrity before power is applied, significantly reducing electric shock risk.
How Do You Choose the Right SHD-GC Cable for Your Operation?
Selecting the correct Type SHD-GC Heavy Duty Cable isn’t just about voltage—it’s about safety, durability, compliance, and long-term reliability.
