Technical Field
The utility model relates to the technical field of cable strands, in particular to an ultra-high-strength galvanized steel strand for a long-span transmission line.
Background
The cable strand wires are high-flexibility special cables which can move back and forth along with a drag chain and are not easy to wear, the cable strand wires are called cable strand wires, the drag cables can be generally called, tank chain cables are arranged on the occasions where equipment units need to move back and forth, in order to prevent the cables from being entangled, worn, pulled off, hung and scattered, the cables are usually placed into the cable drag chain, the cables are protected, the cables can also move back and forth along with the drag chain, the most flexible conductors are selected for the cables, generally speaking, the thinner conductors are, the better the flexibility of the cables is, but the thinner conductors are, and the cable winding phenomenon can be generated. A series of long-term experiments provided an optimum diameter, length and pitch shielding combination for individual conductors, which had an optimum tensile capacity, and the insulation within the cable could not stick to each other. But the insulation also needs to support each individual strand of wire. Therefore, the reliability of the cable is only proven in the application process that high-pressure formed PVC or TPE materials can be used in millions of meters of cables of a drag chain, the shielding layer is tightly woven outside the inner sheath by using an optimized weaving angle, the loose weaving belt reduces the protection capability of EMC, and the shielding layer is also failed due to the breakage of the shielding layer. The tightly woven shielding layer has the function of torsion resistance, and the outer sheaths made of different improved materials have different functions, such as UV resistance, low temperature resistance, oil resistance and cost optimization.
Because most of the existing cable stranded wires are composed of single protection rubber rings and wires, the cables are not provided with corresponding protection and flexibility increasing devices, and the protection rubber rings can deform after being bent for a long time or the wires in the cables can displace to deform.
Therefore, it is necessary to provide an ultra-high strength galvanized stranded wire for a long-span transmission line to solve the above technical problems.
