45 kW loader cable, PUR high wear-resistant polyurethane cable
Product structure
Conductor: Made of multiple strands of finely twisted oxygen-free bare copper wire, complying with VDE 0295 CLASS 5 standards, and tin-plated wire can be provided upon request, ensuring good conductivity and flexibility, capable of withstanding frequent movement, bending, and stretching of the cable during loader operations.
Insulation: Specially modified high-strength elastomer insulation materials meet strict electrical performance requirements, offering excellent insulation and effectively preventing electrical faults such as leakage and short circuits.
Cable Formation: Optimized short-pitch torsionless twisting, with tensile components filled in the center/gap, such as aramid fiber or galvanized soft steel wire rope, to enhance the overall tensile performance of the cable and prevent internal structural damage caused by force during use.
Inner sheath: Made of specially modified high-strength nitrile / PUR material, featuring a low-viscosity strong extrusion design, which protects the cable's internal structure from corrosion by oil, water, chemicals, etc., while also providing some buffering and support for the cable.
Reinforcement layer: usually uses aramid braided reinforcement layers; some products may adopt Kevlar braided torsional structures to further enhance the cable's tensile and torsional resistance, prevent twisting and deformation during winding and dragging, and avoid damage to the internal core wires.
Outer sheath: Made of highly wear-resistant and mechanically superior polyurethane (PUR) material, usually yellow or black. This material has characteristics such as wear resistance, oil resistance, acid and alkali resistance, UV resistance, tear resistance, waterproofing, weather resistance, and aging resistance, effectively protecting cables against corrosion from harsh underground environments and extending cable service life.
Product performance
Electrical performance: The rated voltage is generally 0.6/1KV, with test voltages reaching 3500V - 4000V, meeting the power transmission needs of 45 kW loaders. It has good insulation and stable electrical performance to ensure reliable power and signal transmission during operation.
Mechanical properties: High tensile strength, able to withstand the tensile forces exerted on cables during loader operation; Good torsional resistance, able to withstand torsional stress generated by equipment movement; Excellent bending performance, with a minimum bending radius reaching 8-10 times the cable diameter, suitable for frequent movement and bending of loaders.
Environmental adaptability: The operating temperature range is generally -30°C to 90°C. Some products can operate in environments from -40°C to 100°C, maintaining softness in low temperatures and not experiencing performance degradation or damage in high-temperature environments. At the same time, cables have excellent weather resistance, water resistance, oil resistance, and chemical corrosion resistance, enabling stable operation in humid and dusty underground environments with oil stains and chemicals.
Product advantages
Strong durability: Through optimized structural design and the selection of high-quality materials, the cable can withstand long-term winding, dragging, stretching, twisting, and bending, and is not prone to cracking, breaking, or aging. It has a long service life, which can reduce equipment downtime caused by cable replacement and improve production efficiency.
High stability: Excellent electrical and mechanical properties ensure that cables can steadily transmit power and signals during power supply to the 45 kW electric loader, reducing equipment downtime caused by cable faults and guaranteeing continuity of underground operations.
Good safety: The cables have flame-retardant and leakage resistance, effectively preventing fires and electric shock accidents, ensuring the safety of underground workers and equipment. Additionally, the high wear resistance and tear resistance of the outer sheath also reduce safety hazards caused by cable damage.
Application scenarios
Mainly used in underground mining operations, the 45-kilowatt electric loader provides power transmission and control connections. At the same time, it can also be used in other similar mining machinery such as tunneling machines and rock drilling carts, playing an important role in situations requiring frequent mobile power supply. Additionally, it can be applied to related lifting, transportation, and loading/unloading machinery in waste incineration plants, waste-to-energy plants, lifting and hoisting sites, large logistics sites, iron mines, coal yards, cement plants, sand and gravel plants, port and terminal sites, serving as connecting cables under reels/reels or similar winding and dragging shaft devices
