Special cable

Abstract

The invention relates to the technical field of special cables, in particular to a special cable. The cable comprises a first cable section and a second cable section, wherein the first cable section and the second cable section are of the same structure. Through the arrangement of the transition section, the transition section, the first section of cable and the second section of cable are influenced by wind power, the cable between the two cable racks is influenced by wind power, the swing amplitude of the middle part under wind power is large, and the stretching part is made of an elastic rubber material, so the stretching part has corresponding stretching degree, and the tensile force damage to the cable caused by the tensile force can be further weakened; the diversion fins are arranged, the edges of the outer layers of the diversion fins are arranged to be sharp outer rings, when wind power passes through, the diversion fins divide airflow, and when the airflow passes through the transition section, the upper side and the lower side generate pressure on the transition section due to the shape of the transition section, so the cable can be kept in a balanced state, the pressure difference is increased by the diversion fins, and the stability of the cable can be ensured.

Description

technical field [0001] The invention relates to the technical field of special cables, in particular to a special cable. Background technique [0002] Special cable is a kind of cable used in special fields and special environments. Its characteristics can withstand high temperature, acid and alkali, termites, and wires and cables used in ships, aircraft, nuclear power plants and other occasions. As far as classification is concerned, it does not belong to the same classification method as power, control, computer cables, etc., that is, special cables are also included in the above-listed cables. General special cables need to formulate enterprise internal control standards. [0003] Among them, high-altitude cables are also part of special cables. High-altitude cables are generally installed at high altitudes. Common high-altitude special cables are installed at altitudes exceeding 100 meters, and even some cables are installed at heights exceeding several kilometers. The ...

Problems solved by technology

[0003] Among them, high-altitude cables are also part of special cables. High-altitude cables are generally installed at high altitudes. Common high-altitude special cables are installed at altitudes exceeding 100 meters, and even some cables are installed at heights exceeding several kilometers. The high-altitude environment is more complicated. The production process will increase the diameter of the cable; but there are still defects in this method. First of all, the altitude of the high-altitude cable is high, and the frequency of the harsh weather it encounters is very frequent. Simply increasing the diameter of the cable will increase the resistance of the cable. The windproof performance of the cable deteriorates. In the case of strong wind, the swing range of the cable increases, which is prone to resonance. In addition, when the diameter of the cable increases and ice forms on the cable, its weight will increase, which will increase the pressure on the cable, which will cause The length of the cable increases, which affects the life of the cable, and once the cable freezes, depending on the performance of the cable itself, the cable cannot reduce the load of the cable itself in a short period of time, so long-term maintenance of high load will cause the cable to break. risk
