Product Overview
Mining trailing cables operate in the harshest environments on earth — continuous flexing under high voltage, dragged over sharp rock, soaked in hydraulic fluids, and exposed to extreme temperatures. A cable jacket that fails in these conditions means catastrophic downtime and safety risks.
This mining trailing cable replaces conventional neoprene (CR), CPE, and PVC jackets with a high-performance thermoplastic polyurethane (TPU) sheath. The result is a cable that delivers 10–45× greater abrasion resistance, significantly higher tensile strength, and reliable flexibility down to –30°C — without the toxic smoke burden of halogenated materials.
Built to AS/NZS 2802:2000, ICEA S-75-381, and IEC 60502, this cable is engineered for draglines, continuous miners, shuttle cars, and every mining application where standard jackets fall short. Every production run is tested for Taber abrasion, trouser tear, tensile strength, and flame retardancy to guarantee the performance your operation demands.
At SORIVO, we specialise in custom-engineered cable solutions for the mining and heavy industrial sectors. Our TPU trailing cables are manufactured in strict compliance with international standards and are produced in facilities with extensive cable manufacturing expertise. Learn more about SORIVO →
Key Features
Superior Abrasion Resistance
10–45× better abrasion resistance than CPE, nitrile, and PVC jackets, proven by Taber abrasion testing. Drastically reduces jacket wear in dragline and trailing applications.
TPU Construction
Thermoplastic polyurethane sheath delivers 36–47 MPa tensile strength and 540–600% elongation, outperforming traditional jacket materials by a wide margin.
Halogen-Free FR
Flame retardant TPU meets AS/NZS 1802 with low smoke emission — critical for underground mine safety where toxic fumes from halogenated cables are a life-threatening hazard.
Extreme Cold Flexibility
Reels and flexes reliably at –30°C without cracking or jacket splitting. TPU maintains its elasticity where neoprene and PVC become brittle.
EPR Insulation System
Superior electrical properties with high insulation resistance and low dielectric losses. EPR delivers long service life under continuous 90°C conductor temperature.
Robust Mechanical Design
5.5 mm thick TPU jacket provides exceptional cut-through and notch resistance. Built to withstand the physical punishment of mining operations.
Oil & Chemical Resistant
Excellent resistance to mining oils, hydraulic fluids, diesel, and chemicals. TPU does not swell or degrade when exposed to aggressive mining contaminants.
Custom Core Configurations
Available in 3-power, 3+earth, 3+earth+auxiliary, and multi-core signal combinations. Tailored to your equipment's exact power and control requirements.
