Problems solved by technology

Moreover, ordinary cables generally have requirements for corrosion resistance and oxidation resistance, but the current communication cables generally can only maintain the effect of 5-10 years, and there are relatively few guarantees for the use of more than ten years.
Although some 54-pair cables can improve signal transmission efficiency, for example, the large logarithm cable invented by Mr. Zhao with the publication number 2779565 uses 96 pairs of cables, but the cables are not evenly distributed, which is a waste of space and increases the cost.

Embodiment Construction

[0012] A method for making 54 pairs of cables according to the present invention, which includes 54 pairs of cables 1 wrapped with inner protective sheaths, and outer protective sheaths 2 on the outside of the cables. The 54 pairs of cables are evenly distributed in the outer protective sheaths, and the inner protective sheaths of the cables 3 Close to each other to save space. The inner protective sheath of the cable is made of polyethylene PE and high-quality steel after sandblasting and shot blasting pretreatment, dipping or coating, and heating and curing processes. It has good characteristics such as good insulation performance, high chemical stability, no rust, no aging, and can adapt to harsh environments. The outer protective sheath has a layer of polyimide film protective layer 4, which can prevent external electromagnetic signals from interfering with the cable signal, and can also prevent the radiation generated by the cable signal from affecting the outside world. ...

Abstract

The invention discloses 54 pairs of cables and a manufacturing method thereof. Compared with the prior art, the 54 pairs of cables and the manufacturing method thereof have the advantages that the 54 pairs of cables are used in large pair number cables, the 54 pairs of cables are evenly hinged into a protective jacket, and thus it is guaranteed that the cables have high communication traffic; the outer protective jacket of the cables is formed by a polyimide film protective layer, a high-density PVC layer and a steel tape armoring layer; the large pair number cables are large in communication traffic, the corrosion resistance can be achieved, the service life is long, and radiation is small.

Description

technical field [0001] The invention relates to a cable and a manufacturing method thereof, in particular to a 54-pair cable and a manufacturing method thereof. Background technique [0002] With the rapid development of computer technology and modern communication technology, people's use and demand for information is becoming more and more intense. This has led to the vigorous rise of cutting-edge technologies such as communication automation, office automation, and network communication around the world. Whether it is normal urban and rural electricity consumption, or telephone communication and network communication, cables are required. Ordinary cables are usually rope-like cables that are twisted with at least two wires in each group or groups of wires. Each group of wires is insulated from each other and is often twisted around a center. Highly insulating overlay. Moreover, ordinary cables generally have requirements for corrosion resistance and oxidation resistanc...
