The power supply cable for the specialized drum of the winch crane is designed specifically for the working conditions of the winch and crane drum. It adopts a highly flexible conductor structure, matched with a wear-resistant PUR/NBR sheath, and contains tensile steel wire or Kevlar fiber. It has excellent resistance to torsion, bending, oil and corrosion. Support multi-core power and control signal composite transmission, with a cross-sectional coverage of 1.5-95mm; #178; Resistant to temperatures ranging from -45 ℃ to 120 ℃, suitable for indoor and outdoor heavy lifting, port gantry cranes, metallurgical workshops, and other scenarios, ensuring stable, safe, and durable power supply for equipment.
Special power cable for winch crane drum
1、 Product performance
Anti torsion and bending: Adopting a layered twisted flexible conductor structure, it can withstand high-frequency bending and twisting when the drum is retracted, with a bending life of ≥ 5 million times, meeting the requirements of accompanying movement of lifting equipment.
Tensile, wear-resistant, and weather resistant: Built in tensile steel wire or Kevlar fiber reinforcement layer, with a sheath that is wear-resistant, oil resistant, and UV resistant. It can adapt to a wide temperature range of -45 ℃~+120 ℃ and operate stably in outdoor working conditions.
Signal power composite transmission: supports the composite design of power core and control core, with interference free transmission, suitable for precise control scenarios such as lifting and amplitude adjustment of lifting equipment.
Safety protection: It has excellent insulation and voltage resistance performance, with a flame retardant rating of V0, effectively preventing short circuit and leakage risks, and complying with the safety regulations for lifting machinery.
