Referring to fig. 1 and 2, an environment-friendly low temperature-resistant cable (simply referred to as a "cable") is provided, the cable includes a wire 10, a temperature-resistant layer 20 and a protective layer 30, wherein: the wire 10 includes a core wire 11 and a sheath 12 covering the periphery of the core wire 11. In this example, the core wire is copper wire or tin-plated copper wire. Taking a tinned copper wire as an example, the tinned copper wire (namely 'copper wire tinning') can prevent adhesion with the insulating sheath, so that the core wire is prevented from blackening and becoming brittle, and the weldability is improved; it can also prevent oxidation-reduction reaction and generate copper green, and can increase heat dissipation and improve conductivity and wire performance. The sheath 12 is an insulating sheath formed by copolymerizing tetrafluoroethylene and hexafluoropropylene (referred to as "FEP") and is extruded by an extruder to form a coated core wire. The FEP crystallization melting point was 304℃and the density was 2.15g/CC (g/CC). FEP can be applied to soft plastics, which have lower tensile strength, abrasion resistance, creep resistance than many engineering plastics. It is chemically inert and has a low dielectric constant over a wide temperature and frequency range. In this example, the extruder (also referred to as an "extruder") is a wire and cable device mainly used for extruding core wires of wires and cables such as power wires, cables, coaxial cables, communication cables, transmission cables, and rubber-covered cables. The working flow of the extruder comprises the following steps: ① Copper wires are released from the pay-off rack and pass through the extruder head, and meanwhile, sizing materials are sucked into the extruder head through the material sucking machine for heating; ② Encapsulating the copper wire by a host; ③ Traction is carried out through a traction machine; ④ Winding and coiling by a winding machine; the heat-resistant layer (commonly called as 'wrapping tape') 20 is a ribbon like paper formed by cotton materials, and is wrapped on the periphery of a plurality of wires in a binding mode, at least one group (two adjacent wires are indicated) of the wires is wrapped on the periphery by adopting aluminum foil (a), and the aluminum foil mainly plays roles of shielding a net wire and assisting product stabilization; the protective layer (commonly called as an outer coating) 30 is made of polyvinyl chloride material, and is processed and coated on the outer periphery of the temperature resistant layer through an automatic machine (similar to an extruder) so as to complete the environment-friendly low-temperature resistant cable process. The polyvinyl chloride, english PVC (Polyvinyl chloride) for short, is a polymer formed by polymerizing vinyl chloride monomer (vinyl chloride monomer, VCM for short) under the action of initiator such as peroxide and azo compound or light and heat according to free radical polymerization reaction mechanism. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.
In the foregoing embodiments, the descriptions of the embodiments are focused on, and the parts of a certain embodiment that are not described or depicted in detail may be referred to in the related descriptions of other embodiments.
It should be noted that the above embodiments can be freely combined as needed. The foregoing is merely a preferred embodiment of the present utility model and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the present utility model, which are intended to be comprehended within the scope of the present utility model.
