Shanghai Suoqi Cable Co., Ltd. has been deeply engaged in the field of special flexible cables. Below is a professional interpretation of reel cables from three dimensions: material structure, performance advantages, and application scenarios.
1. Materials and Structural Parameters
Special cable for 37 kW electric LHD (Load-Haul-Dump) machines (reel cable). Product structure: it adopts multi-strand finely stranded bare oxygen-free fine copper wires, complying with VDE 0295 CLASS 5 standard, with good conductivity and flexibility, able to withstand frequent bending and stretching; insulation: special modified high-strength elastomer insulation material, meeting strict electrical performance requirements, effectively preventing leakage and ensuring the safety of equipment and personnel; stranding: optimized short-pitch non-torsion stranding with central/interstitial tensile elements such as aramid fiber and galvanized soft steel wire rope, enhancing the cable's tensile performance; inner sheath: special modified high-strength NBR/PUR material is selected to protect the internal structure of the cable from oil, water, chemicals, etc.; reinforcement layer: usually aramid braid reinforcement or Kevlar braid anti-torsion structure, improving the cable's tensile and torsion resistance and preventing twisting and deformation during use; outer sheath: highly abrasion-resistant polyurethane (PUR) material with better mechanical properties, generally yellow or black, featuring wear resistance, oil resistance, acid and alkali resistance, UV resistance, tear resistance, etc., able to adapt to the harsh underground working environment. Product performance - Electrical performance: the rated voltage is generally 0.6/1kV, meeting the power transmission needs of the 37 kW electric LHD machine; the test voltage can reach 4000V, with good insulation performance, ensuring that no leakage, short circuit or other electrical faults occur during operation; mechanical performance: high tensile strength, able to withstand the tensile force applied to the cable during LHD operation; good torsion resistance, able to resist the torsional stress generated by equipment movement; excellent bending performance, with a minimum bending radius of 6-8 times the cable diameter, adapting to the frequent movement and bending of the LHD machine; environmental adaptability: the working temperature range is generally -30℃ to +90℃; it remains soft in low-temperature environments and does not suffer performance degradation or damage in high-temperature environments. Meanwhile, the cable has good weather resistance, water resistance, oil resistance and chemical corrosion resistance, and can work stably in underground environments that are humid, dusty, oily and chemically contaminated. Product advantages - Strong durability: through optimized structural design and high-quality material selection, the cable can withstand long-term winding, dragging, stretching, torsion and bending, and is not prone to cracking, breakage, aging and other problems, with a long service life; high stability: good electrical and mechanical performance ensures that the cable can stably transmit power and signals while supplying power to the 37 kW electric LHD machine, reducing equipment downtime caused by cable faults and improving production efficiency.
Good safety: the cable has flame-retardant and tracking-resistant properties, which can effectively prevent fire and electric shock accidents and ensure the safety of underground operations.
Application scenarios: it is mainly used for the 37 kW electric LHD machine in underground mining operations, providing power transmission and control connections. It can also be used for other similar mining machinery and equipment, such as drill jumbos and roadheading machines, playing an important role in occasions requiring frequent mobile power supply.
2. Performance and Technical Indicators
