In modern mining and heavy industry, safe and reliable power distribution is a cornerstone of productivity. South Africa, home to some of the world’s largest mining operations, requires advanced cable technology to power equipment such as longwall shearers, continuous miners, shovels, dredges, and drilling rigs. One of the most trusted solutions is the Type SHD-GC three-conductor round portable power cable with CPE jacket, rated up to 25 kV.
Engineered to meet demanding conditions, this cable balances high electrical performance, mechanical durability, and compliance with international standards such as ICEA S-75-381, ASTM B 172, ASTM B 33, and CAN/CSA C22.2 No. 96. Its robust construction and safety features make it a preferred choice for operators in regions where heavy-duty, flexible, and safe cables are essential.
Key Benefits of Type SHD-GC Cable
Durability in Harsh Environments
Designed for mining operations where mechanical stress, moisture, abrasion, and chemical exposure are common.
Enhanced Safety
Ground check conductor provides continuous monitoring to prevent accidents.
Flame-retardant and oil-resistant jacket reduces fire risks.
Flexibility and Mobility
Suitable for portable applications, including reeling, trailing, and festooning systems.
Extended Service Life

Compliance with International Standards
Meets ICEA, ASTM, CSA, and NEMA requirements, ensuring reliability and performance.
Applications in South Africa’s Mining and Heavy Industry
South Africa’s economy is deeply rooted in mining, from gold and platinum to coal and manganese. Equipment in these operations demands cables capable of handling high voltage, heavy loads, and extreme conditions.
Common Applications
Underground Mining: Longwall shearers and continuous miners.
Open-Cast Mining: Shovels, drills, draglines, and conveyor systems.
Industrial Operations: Dredging, tunneling, and heavy construction equipment.
Ports and Logistics: Powering cranes and bulk material handling systems.
Installation and Maintenance Recommendations
To maximize the life of Type SHD-GC cables, proper installation and routine inspection are critical.
Installation Best Practices
Maintain minimum bending radius of 8×OD.
Avoid sharp edges or over-tight cable clamps.
Use reels or festoon systems for moving equipment.
Ensure proper grounding before energizing.
Maintenance Guidelines
Conduct regular visual inspections for abrasion, cuts, or jacket swelling.
Test ground check conductor continuity.
Monitor insulation resistance to detect early failures.
Store cables in a cool, dry environment when not in use.
Frequently Asked Questions (FAQ)
1. What does SHD-GC stand for?
SHD = Shielded, High-Voltage, Portable Power Cable.
GC = Ground Check.
2. What is the voltage rating of Type SHD-GC cable?
Typically available up to 25 kV, depending on design.
3. Why is the ground check conductor important?
It continuously monitors grounding integrity, preventing dangerous faults in portable mining equipment.
4. Can Type SHD-GC be used in wet conditions?
Yes, its CPE jacket provides moisture and chemical resistance.
5. How does it compare with Type G-GC cable?
Type G-GC is rated up to 2 kV and used for lighter applications, while SHD-GC is a high-voltage cable designed for heavy-duty mining.
6. Does it comply with South African standards?
While primarily designed to ICEA/ASTM, many suppliers adapt SHD-GC cables to SANS 1520-1 and NRCS requirements for local compliance.
The Type SHD-GC three-conductor round portable power cable is a proven solution for South Africa’s mining and heavy industrial operations.
