Description

A kind of heat modification softness PVC cables

Technical field

The utility model is related to a kind of cable, specifically a kind of heat modification softness PVC cables.

Background technology

Cable is a kind of power Transmission equipment, can carry out remote power transmission, and the Working Life for giving people brings Great convenience, with continuing to develop for China's economy, the electric automatization degree of equipment more and more higher, at this time Need to use substantial amounts of cable.

The exterior material of cable be typically all by PVC support, occur fire when produce it is substantial amounts of have severe toxicity, have corruption The HCL gases of corrosion, can also produce substantial amounts of hypertoxic dense smoke, cause great life and property loss, and cause to rescue work Very big difficulty, while the cable core of cable is typically provided with protective case, protective case is typically by rubber and plastics organic polymer Form, and typically all one layer, the protection to cable core in some environment is inadequate, is especially extruded by the external world, Often it is damaged to cable core.

Therefore, for the problem proposed in above-mentioned background technology, those skilled in the art propose a kind of new PVC electricity Cable.

Utility model content

The purpose of this utility model is to provide a kind of heat modification softness PVC cables, to solve to be carried in above-mentioned background technology The problem for going out.

To achieve the above object, the utility model provides following technical scheme：

A kind of heat modification softness PVC cables, including support frame, shell, pointed raised and connecting portion, support frame as described above include Support ring, supporting plate and support bar, support ring, supporting plate and support bar are made by elastomeric material, the periphery setting of support bar There is support ring, the cross section of support bar is circle, and three supporting plates are provided between support bar and support ring, and supporting plate is uniformly divided Cloth is on the excircle of support bar；Support ring is divided into three cavitys by the supporting plate, and metal is provided with each cavity Conductor, metallic conductor is formed by many copper wires are stranded；Support frame as described above outer wrap has screen layer, and screen layer is metal net layer； The screen layer outside is enclosed with non-woven fabrics belting layer, and non-woven fabrics belting layer outside is enclosed with a TPV thermoplastic elastomers, First TPV thermoplastic elastomers outside is enclosed with armor, and armor 5 is that zinc-coated wire braiding is formed, armor outside bag It is wrapped with the 2nd TPV thermoplastic elastomers；The 2nd TPV thermoplastic elastomers outside is enclosed with waterproof layer, waterproof layer bag Shell is wrapped with, shell is made up of the crosslinked halogen-free material that high temperature resistant is irradiated；It is provided with the excircle of the shell multiple pointed Projection, is fixedly connected with connecting portion on the excircle of shell, screwed hole, the screwed hole internal thread of connecting portion are offered on connecting portion Threaded rod is connected with, the bottom of threaded rod is taper.

Further, the heat modification softness PVC cables.

Further, mineral matter fire proofing is filled with the space between cavity and metallic conductor.

Further, diameter of the length of the threaded rod more than shell.

Compared with prior art, the utility model passes through a TPV thermoplastic elastomers and the 2nd TPV thermoplastic elastics Body layer shows resilient property at normal temperatures, plasticizing forming at high temperature, not only possesses that traditional rubber is ageing-resistant, spy with strong elasticity Point, it is easy to process but also with common plasticses, while metallic conductor is arranged in flexible supporting frames, can effectively exclude the external world Pressure, improves the anti-pressure ability of cable, at the same be filled with space between cavity and metallic conductor mineral matter fire proofing and The non-woven fabrics belting layer of setting can improve the refractory ability of cable, and shell is made up of the crosslinked halogen-free material that high temperature resistant is irradiated, Even if burning will not also produce the toxic gas with halogen, while the waterproof ability of cable is very strong, can also conveniently be consolidated It is fixed.
