Wuyuan lead source line with the limited production of Dyneema fiber are: an ultra strong polyethylene fiber, gel spinning method for the production, with the following characteristics: 1) high tensile strength Dyneema fiber is effective in improving bearing force, its low elongation can be controlled effectively sag, making it subject to such load carrying case, Fox dropped off as small as possible, to ensure that device and live power censorship clearance distances to meet safety requirements 2) Dyneema fiber has excellent insulation and moisture in live performance guarantees over security during construction personnel and equipment. 3) bag jacket strong breeze Masheng unaffected by vibration, off shares and the reduction of the intensity of this influence does not exist. 4) Dyneema fiber material light, breaking tensile strength equal conditions, Dyneema lines per meter weighs only 15% of the rope, using Dyneema lines will help reduce labor intensity and improve the effectiveness and timeliness. 5) Dyneema fiber good resistance to bending fatigue performance, wear resistance, UV and chemical resistance and other characteristics, is conducive to recycling across construction.
