Electric traction ropes are ropes used in the fields of electric power, telecommunications, railways, and communications to release wires, cables, and optical cables. For the first time, it is called the first-level traction rope, and the first-level traction rope is called the second-level traction rope.
Electric traction rope can be divided into the following categories: mechanically braided steel wire anti-twist traction rope, Dyneema traction rope, Dupont wire traction rope, nylon traction rope.
Our commonly used electric traction lines mainly include mechanically braided steel wire anti-twist traction ropes and Dyneema traction ropes.
Mechanically braided steel wire anti-twist traction rope: when subjected to tension in a free state, the rotation angle of the anti-twist wire rope is zero, and the synthetic torque is zero, which is suitable for various fields that require the wire rope not to rotate; the rope has good flexibility and can be released It does not twist or shrink after tension, and has a long service life, and can use different structures of strands according to the working conditions; the anti-twist steel wire rope can be plugged to make the practical length up to any length without any additional connectors. The local damage during use can also be repaired by plugging, without reducing the breaking force and flexibility of the whole rope; the raw material of the anti-twist steel wire rope is galvanized aviation steel wire, which has the characteristics of high strength and corrosion resistance.
Dyneema traction rope: light weight and high strength (with the same diameter and the same strength, its weight is less than 1/7 of that of the steel cable), making the operation more convenient and fast; the twelve-strand braided anti-twist structure. Low elongation makes the operation faster and safer; anti-bending fatigue, anti-corrosion, anti-ultraviolet performance, not affected by salt water and non-absorbent are all its advantages, improving the durability of the rope; the rope is treated with resin, And adding sheath protection, not only facilitates repair and maintenance, but also improves the service life and makes the investment more effective; the withstand voltage insulation brings more convenience to the construction without power failure, and is currently the most ideal product for live spanning.
Electric traction ropes are mainly used for power transmission and transformation and telecommunication aerial line release and traction transition under various complex terrain conditions; load-carrying cables for live spanning; balance hanging line anchor lines; hanging insulators; first traction rope for bridge building (helicopter line) etc.
