Specially modified high-strength elastomer insulation material meets strict electrical performance requirements, has excellent insulation effects, and can effectively prevent electrical faults such as leakage and short circuits.
Optimized short-pitch, torque-free stranding, central/interstitial filler tensile elements such as aramid fibers or galvanized soft steel wire ropes enhance the overall tensile performance of the cable and prevent damage to the internal structure under force during use.
Inner Sheath
Made of specially modified high-strength nitrile/PUR materials, using a low-viscosity high-strength extrusion design, it can protect the internal structure of the cable from damage by oil, water, or chemicals, while providing the cable with some cushioning and support.
Strengthening Layer
Typically uses an aramid braided strengthening layer; some products may use Kevlar braided anti-torsion structures to further enhance the cable's tensile and torsion resistance, preventing twisting or deformation during winding or dragging and avoiding damage to the internal conductors.
Outer Sheath
Made of highly wear-resistant and mechanically superior polyurethane (PUR) material, typically yellow or black in color. This material has properties such as wear resistance, oil resistance, acid and alkali resistance, UV resistance, tear resistance, waterproof, weather resistance, and aging resistance, effectively protecting the cable from harsh underground environments and extending cable service life.
Product performance
Electrical performance
The rated voltage is generally 0.6/1KV, and the test voltage can reach 3500V - 4000V. It can meet the power transmission requirements of a 45-kilowatt shovel loader, has good insulation performance and stable electrical performance, ensuring reliable transmission of power and signals during operation.
Mechanical properties
It has 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 of 8 to 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, and some products can operate in environments from -40°C to 100°C, remaining flexible at low temperatures and maintaining performance without deterioration or damage at high temperatures. At the same time, the cable has good weather resistance, water resistance, oil resistance, and chemical corrosion resistance, allowing it to work stably in underground environments that are humid, dusty, oily, and contain chemical substances.
Product advantages
Strong durability
Through optimized structural design and high-quality material selection, 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
Good electrical and mechanical performance ensures that cables can stably transmit power and signals during the power supply process for the 45 kW electric loader, reducing equipment downtime caused by cable faults and guaranteeing continuity of underground operations.
Good safety
The cable has features such as flame retardancy and resistance to electric leakage, which can effectively prevent fires and electric shock accidents, ensuring the safety of underground workers and equipment. At the same time, the high wear resistance and tear resistance of its outer sheath can 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
