Understanding Heavy-Duty Cable Types
Heavy-duty cables are designed for demanding applications where standard cables would fail. The Type SHD-GC cable, for instance, is a three-conductor round portable power cable with a Thermoplastic Polyurethane (TPU) jacket, rated for 2kV, and compliant with standards like ICEA S-75-381, NEMA WC 58, ASTM B 172, ASTM B 33, and CAN/CSA C22.2 No. 96. These cables are tailored for heavy mobile equipment and power feeders in harsh environments.
Key Cable Types for Mining and Heavy Industry
Type SHD-GC: A three-conductor cable with a grounding conductor and ground check conductor, ideal for high-voltage mobile equipment in mining.
Type W: Single or multi-conductor cables for portable power applications, often used in less abrasive environments.
Type G-GC: Similar to SHD-GC but with additional grounding conductors for enhanced safety.
MP-GC (Mine Power Feeder Cables): Designed for stationary power distribution in mines, offering high durability and flexibility.
Each cable type serves specific purposes, with Type SHD-GC being particularly suited for South Africa’s mining sector due to its rugged construction and ability to handle extreme conditions.
Benefits of Type SHD-GC Cables
Durability: The TPU jacket and EPR insulation provide exceptional resistance to abrasion, chemicals, and extreme temperatures.
Flexibility: Stranded conductors and a minimum bending radius of 6×OD allow for easy maneuvering in tight spaces.
Safety: Grounding and ground check conductors ensure reliable grounding, reducing the risk of electrical faults.
Versatility: Suitable for a wide range of heavy equipment, from draglines to power feeders.
Customizability: Options for alternative jacket materials and two-layer designs cater to specific needs.
