High temperature ultra-flexible electric cable and production method

Abstract

The invention discloses a manufacturing method of a high temperature cable with super flexibility. The method comprises the following steps: (1), an insulating layer with polytetrafluoroethylene material is extruded and formed on a conductor, and line conductors are formed; (2), the line conductors are centralized and intertwisted, and a cable core is formed; (3), a mica tape is used to wrap the cable core, and a mica belting layer is formed; (4), copper mesh is braided at the periphery of the mica belting layer, and a copper mesh braid ply is formed; (5), fluororubber is used to extrude and form a fluororubber layer outside the copper mesh braid ply, and an embryo covering is formed; and (6), by using an electron accelerator, the embryo covering is processed to an irradiation crosslinking fluororubber covering. The cable manufactured through the method is provided with the copper mesh braid ply, the mica belting layer and the irradiation crosslinking fluororubber covering, so that the cable has the advantages of good tensile strength, small resilience and permanent deformation, ozone resistance, ultraviolet radiation resistance, oil resistance, various chemical corrosion resistance, and good high temperature resistance and flexibility.

Description

technical field [0001] The invention relates to a cable, in particular to a high-temperature super-flexible cable with good physical and chemical properties and a manufacturing method. Background technique [0002] The application of wire and cable is mainly divided into three categories: power system, information transmission system and engineering equipment, and instrumentation system. The wire and cable products used in the power system mainly include overhead bare wires, bus bars (bus bars), power cables, rubber sheathed cables, overhead insulated cables, branch cables (replacing part of the bus bars), electromagnetic wires, and electrical equipment wires and cables for power equipment, etc. . The wires and cables used in the information transmission system mainly include local telephone cables, TV cables, electronic cables, radio frequency cables, optical fiber cables, data cables, electromagnetic wires, power communication or other composite cables, etc. Except for o...

Problems solved by technology

[0004] Generally, when the wires and cables on the market are used in the above-mentioned special fields, because the wires and cables are exposed outdoors or in some harsh environments, such as strong corrosive media and strong oxidants, ozone, ultraviolet radiation, high temperature and oily and various Under the harsh environment of chemical corrosion, on the one hand, the above-mentioned wires and cables may be damaged in a short period of time and the wires and cables need to be replaced in advance, which will increase the cost of the enterprise and shorten the normal life of the wires and cables; at the same time, exposed to outdoor The wires and cables are often subject to ultraviolet erosion and chemical reactions under the action of rain and wind, making the shielding effect of the wires and cables worse and worse as the wires and cables are damaged, affecting the quality and reliability of signal transmission and shortening the length of the wires and cables. At the same time, wires and cables are repeatedly bent in the industry, but with the passage of time, more and more deformation occurs, and the resilience is poor, which accelerates the premature failure of wires and cables and increases the impact on wires and cables. Increased environmental pollution due to usage

On the other hand, the components or electronic and electrical equipment connected to the wire and cable are damaged
