In South Africa, mining remains the backbone of the economy. From deep-level gold mines in Gauteng to sprawling platinum operations in the North West and Limpopo, reliable electricity is indispensable. Heavy mobile equipment such as continuous miners, longwall shearers, shovels, and dredges depend on robust, flexible power cables that can endure mechanical stress, harsh environmental conditions, and continuous movement.
One of the most widely adopted solutions is the Type SHD-GC three-conductor portable power cable with TPU jacket 15kV, manufactured to meet ICEA S-75-381 and NEMA WC 58 standards. This cable is designed to deliver both electrical performance and mechanical resilience, making it a critical technology in modern mining and industrial environments.
Cable Overview: Type SHD-GC Portable Power Cable
What is SHD-GC?
SHD: Shielded, Heavy-Duty
GC: Ground Check
The cable is a flexible, heavy-duty, shielded power cable designed for use in medium-voltage (up to 15 kV) applications, especially where equipment is mobile, continuously re-positioned, or exposed to mechanical stress. The ground check conductor is a safety feature that allows monitoring of the grounding system integrity, a crucial requirement in mining operations.
Standards and Compliance
ICEA S-75-381 / NEMA WC 58 – U.S. standard for portable and power cables.
ASTM B 172 / ASTM B 33 – Governs conductor quality and performance.
CAN/CSA C22.2 No. 96 – Canadian compliance for mining and portable cables.
These standards ensure that SHD-GC cables meet stringent safety, durability, and performance benchmarks.
