Specially modified high-strength elastomer insulation meets stringent electrical performance requirements, offering good insulation that effectively prevents electrical faults such as leakage and short circuits.
Optimized short-lay-length torsion-free stranding with central/interstitial fill tensile elements—such as aramid fibers or galvanized flexible steel wire ropes—enhances the cable's overall tensile performance and prevents internal structural damage caused by forces during use.
Inner Sheath
Specially modified high-strength NBR/PUR material with a low-viscosity, high-pressure extrusion design protects the cable's internal structure from oil, water, chemicals, and other erosion, while providing certain buffering and support.
Reinforcement Layer
Typically an aramid braided reinforcement layer; some products use a Kevlar braid anti-twist structure to further improve tensile and torsion resistance, preventing twisting and deformation during winding and dragging and avoiding damage to internal cores.
Outer Sheath
High-abrasion polyurethane (PUR) with superior mechanical properties, generally yellow or black. It is wear-resistant, oil-resistant, acid/alkali-resistant, UV-resistant, tear-resistant, waterproof, weather-resistant, and anti-aging, effectively protecting the cable against harsh underground environments and extending service life.
Product Performance
Electrical Performance
Rated voltage is generally 0.6/1 kV with test voltage up to 3500V–4000V, meeting the power transmission needs of 45 kW LHD (load-haul-dump) machines, with good insulation and stable electrical performance for reliable power and signal transmission during operation.
Mechanical Performance
High tensile strength withstands the stretching forces of LHD operations; good torsion resistance withstands torsional stress from equipment movement; excellent bending performance with a minimum bending radius of 8–10× cable diameter, adapting to the frequent movement and bending of LHD machines.
Environmental Adaptability
Operating temperature range is generally -30℃ to +90℃, with some products working from -40℃ to +100℃, staying soft at low temperatures without performance degradation or damage at high temperatures. The cable also offers good weather resistance, water resistance, oil resistance, and chemical corrosion resistance, working stably in damp, dusty, oily underground environments with chemical exposure.
Product Advantages
Strong Durability
Through optimized structural design and premium materials, the cable endures long-term winding, dragging, stretching, twisting, and bending without cracking, breaking, or aging, delivering long service life and reducing equipment downtime from cable replacement, improving production efficiency.
High Stability
Good electrical and mechanical performance ensures stable power and signal transmission when powering 45 kW electric LHD machines, reducing downtime caused by cable failure and safeguarding underground operation continuity.
Good Safety
Flame-retardant and tracking-resistant properties effectively prevent fire and electric shock accidents, protecting underground personnel and equipment. The sheath's high abrasion and tear resistance also reduces safety hazards from cable damage.
Application Scenarios
Mainly used for 45 kW electric LHD machines in underground mining, providing power transmission and control connections. Also applicable to similar mining machinery such as roadheaders and drilling jumbos wherever frequently moved power supply is needed. Additionally, it can serve hoisting, transport, and loading/unloading machinery at waste incineration plants, waste-to-energy plants, lifting sites, large logistics sites, iron ore yards, coal yards, cement plants, aggregate plants, ports, and docks—as the connecting cable under reels/drums or similar winding spool devices.
