The 4x10: PUR polyurethane drum cable with abrasion resistance, tension resistance and torsion resistance shall be used for mining electric scraper, rock drill, trolley, electromagnetic sucker reeler, garbage grab and crane. The reel cable is retracted and expanded along with the guide of the towing axle or other similar devices. The outer sheath is imported TPU/PUR polyurethane, which has super wear resistance and can be used for dragging back and forth on the gravel ground of the mine for a long time. The bulletproof silk Kevlar braid is added in the middle, so that the cable has super tensile property. Good cable structure makes the cable also resistant to vehicle/crushed stone rolling. The overall performance is good, which can completely replace imported cables.
Cable product features:
1. High abrasion resistance: the ore wears the cable severely, and the outer sheath of the cable must be able to withstand the friction of the ore for a long time without damage.
2. High tensile strength: in ore mining, the length of cable is relatively long, and the friction force on the ground is very large, so the tension on the cable will be very large in the use of moving back and forth, which requires a strong tensile strength of the cable, and the core wire will not break in the dragging of the cable.
3. Torsion resistance: the cable needs to be dragged for a long distance in the underground roadway, and often turns in the roadway, which will inevitably cause cable torsion, which requires that the cable has a particularly strong torsion resistance, the cable will not be deformed due to torsion, and the sheath will not crack.
4. Waterproof and corrosion resistance: In underground ore mining, there may be water or corrosive liquid, which requires that the cable has sufficient waterproof and corrosion resistance.
