Benefits of Heavy-Duty Cables
Heavy-duty cables like Type SHD-GC offer several advantages:
Durability: The TPU jacket and robust construction resist abrasion, chemicals, and extreme temperatures, ideal for harsh mining environments.
Flexibility: A minimum bending radius of 6×OD allows for easy installation in confined spaces.
Safety: Ground check and grounding conductors ensure fault detection and safe operation.
High Ampacity: Supports heavy machinery with high power demands, reducing the need for multiple cables.
Versatility: Suitable for applications like draglines, shovels, dredges, drills, and power feeders.
Usage Scenarios in South Africa’s Mining and Heavy Industry
South Africa’s mining sector, a cornerstone of the economy, relies heavily on robust power solutions. Heavy-duty cables like Type SHD-GC are integral to various applications:
Open-Pit Mining
In open-pit mines, such as those in the Northern Cape, draglines and shovels require flexible, high-ampacity cables to power massive electric motors. The Type SHD-GC’s TPU jacket withstands abrasive rock surfaces and extreme temperatures, while its ground check conductor ensures safety in high-voltage operations.
Underground Mining
In underground gold or platinum mines, such as those in Gauteng or Mpumalanga, cables power drills and ventilation systems. The cable’s flexibility and compact design make it ideal for confined spaces, while its EPR insulation protects against moisture and heat.
Heavy Industry
In industrial plants, such as steel manufacturing facilities in Mpumalanga, Type SHD-GC cables serve as power feeders for heavy machinery. Their high ampacity supports energy-intensive processes, and the TPU jacket resists chemical exposure from industrial processes.
es’ 243A ampacity (3×2/0 AWG) supported the mine’s draglines, boosting operational efficiency.
