Excavator Cable Designed for High Flexibility and Durability
Tunnel boring machine (TBM) cables are special cables designed for use with TBMs and shield tunneling machines. They must meet performance requirements such as high wear resistance, high temperature resistance, tensile strength, moisture resistance, and flame retardancy under extreme working conditions. These special power cables are designed for various tunneling equipment (such as tunneling trolleys, mining machines, and TBMs) under moving, dragging, and winding conditions, and must meet the requirements of high strength, high wear resistance, and stable operation in complex environments. They utilize multi-strand oxygen-free copper wire (OCS) stranding, conforming to VDE 0295/CLASS 5 standards. The square design ensures current carrying capacity and flexibility, and resistance to fatigue fracture. The insulation layer uses high-quality mixed elastomer or special rubber, with excellent voltage resistance. Common rated voltages are 0.6/1kV, and test voltages are 3500V-4000V. A double-…
