ICEA S-75-381 Type SHD-GC Three-Conductor Round Portable Power Cable TPU Jacket 15kV for Drag Lines, Shovels, Dredges, Drills and for Power Feeders

When powering drag lines, electric shovels, dredges, drills, and mobile power feeders, not all high-voltage cables are created equal. ICEA S-75-381 Type SHD-GC Three-Conductor Round Portable Power Cable with TPU Jacket (15kV) is specifically engineered to survive the mechanical abuse, electrical stress, and harsh environments typical of large-scale surface and underground mining operations.

What Does “Type SHD-GC” Mean in ICEA S-75-381 Cables?

Type SHD-GC is a standardized designation under ICEA S-75-381 / NEMA WC 58 for Shielded Heavy-Duty, Ground-Check portable power cables.

Breaking it down:

• S (Shielded) – Each phase conductor is electrically shielded to control electric stress and reduce partial discharge.

• H (Heavy-Duty) – Designed for severe mechanical conditions and repeated flexing.

• D (Extra Heavy Duty) – Enhanced insulation and mechanical robustness.

• GC (Ground Check) – Includes a dedicated ground-check conductor for continuous grounding integrity monitoring.

This construction makes SHD-GC cables suitable for 15kV class mobile equipment, where safety, reliability, and durability are non-negotiable.

What Standards Does Type SHD-GC 15kV Portable Power Cable Comply With?

Type SHD-GC cables are manufactured to meet multiple international standards:

• ICEA S-75-381 / NEMA WC 58 – Portable power and mining cable requirements

• ASTM B172 – Tinned copper conductors

• ASTM B33 – Tinned copper wire

• CAN/CSA C22.2 No. 96 – Portable power cable safety compliance

These standards ensure electrical performance, mechanical endurance, and safety compliance across global mining markets, including Australia, and the Americas.

How Is ICEA S-75-381 Type SHD-GC 15kV Cable Constructed?

What Type of Conductor Is Used?

• Stranded annealed tinned copper

• High flexibility, excellent conductivity, and corrosion resistance in wet or chemically aggressive environments

Why Is a Conductor Shield Necessary?

• A conductive layer around each conductor ensures uniform electric stress distribution

• Reduces insulation aging and partial discharge risk at 15kV

What Insulation Material Is Used and Why?

• Ethylene Propylene Rubber (EPR)

• Chosen for:

  • High dielectric strength

  • Excellent heat resistance

  • Superior flexibility compared to XLPE

How Does the Insulation Shield Improve Safety?

• Conductive tape + tinned copper/textile braid

• Provides:

  • Controlled electric field

  • Effective grounding

  • Improved fault detection

What Is the Function of the Ground Check Conductor?

• Tinned copper conductor with yellow polypropylene insulation

• Enables ground-monitoring systems to instantly detect grounding failures

Why Use a TPU Jacket Instead of Traditional Rubber?

The Thermoplastic Polyurethane (TPU) jacket offers:

• Exceptional abrasion and cut resistance

• Superior oil, fuel, and chemical resistance

• Lower friction for easier dragging over rock and soil

• Better performance in cold and hot climates

Where Is Type SHD-GC 15kV Portable Power Cable Typically Used?

Why Are Drag Lines and Electric Shovels Ideal Applications?

• Continuous movement and cable dragging

• High current demand

• Harsh mechanical abuse

Why Is SHD-GC Used for Dredges and Drills?

• Wet, abrasive, and chemically aggressive environments

• Need for reliable grounding and fault detection

How Is It Used as a Power Feeder?

• Temporary or semi-permanent power supply to mobile substations

• Safer than rigid MV cables in dynamic layouts

What Installation Practices Maximize Service Life?

How Should Bending and Routing Be Managed?

• Maintain minimum bending radius (8×OD)

• Avoid sharp edges and pinch points

What About Handling and Storage?

• Do not twist under tension

• Store on reels in dry, shaded areas

Why Is Ground Check Testing Critical?

• Verify continuity before energizing

• Essential for compliance and personnel safety
