Description
Technical field
The utility model relates to field of cables, particularly relates to a kind of industrial flexible shielding industrial cable.
Background technology
At present, along with the development of science and technology, the demand of people to cable also gets more and more, cable is a kind of common data-signal transmission equipment, there is message capacity large, the advantages such as the high and security performance of transmission stability is good, but existing cable covering uses some comparatively general polymer, not only useful life is short, and the situation of contaminated environment can be there is, and existing cable is because of the complicated variation of its operational environment, in the cable course of work, the external world there will be some stronger electromagnetic waves and disturbs it, cable is caused to occur unsure state in transmitting procedure, signal is caused externally to reveal, very large loss is brought to enterprise.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the purpose of this utility model is to provide a kind of industrial flexible shielding industrial cable.
The utility model is taked following technical scheme to realize: a kind of industrial flexible shielding industrial cable, and it comprises cable body, and described cable body comprises conductor, insulating barrier, screen and oversheath, and described cable body cross section is circular configuration; Described cable body inside is provided with some conductors; Described conductor is outer to be fixedly connected with by PVC plastic connecting rod; Outside described PVC plastic connecting rod, one deck insulating barrier is set; The gap portion of described insulating barrier and PVC plastic connecting rod is provided with water blocking layer; Described insulating barrier closely extrudes one deck screen outward; Described screen closely extrudes armour, reinforcing braid and packed layer from inside to outside successively; Some guide cores are provided with in described armour; One deck oversheath is extruded outside described packed layer.
The industrial flexible shielding industrial cable of above-mentioned one, described conductor is the core of naked copper or tin plated materials and forms as the carbon fibre material strengthening structure is stranded.
The industrial flexible shielding industrial cable of above-mentioned one, described insulating barrier, screen, Thickness Ratio between armour and reinforcing braid are 1:1:1:1.
The industrial flexible shielding industrial cable of above-mentioned one, the armour that described cable body inside is arranged is coated steel strips.
The industrial flexible shielding industrial cable of above-mentioned one, described insulating barrier is inorganic thin film, PVC coating or elastomeric material are made.
The industrial flexible shielding industrial cable of above-mentioned one, described reinforcing braid material is that polyolefine material is made.
Owing to have employed such scheme, compared with prior art, the utility model has following beneficial effect:
1, described reinforcing braid adopts the corrosion-resistant polyolefine material of low-smoke bittern-free highly fire-proof of resistance to chemical attack to make, make it have good resistance to aromatic solvent, soda acid chemicals and oil based solvent corrosive power, higher anti ageing property, less insulation dielectric loss, thus reach etch-proof performance.
2, described conductor is the core of naked copper or tin plated materials and forms as the carbon fibre material strengthening structure is stranded, not only substantially increase the operating efficiency of cable, also make its work more stable, and described conductor structure is easy to processing, making length is unrestricted, there is during use certain flexibility and bendability, facilitate the laying of workpeople.
3, described armour is coated steel strips, and described steel band is good magnetic material, has good shielding action to electromagnetic wave, can effectively prevent the high-frequency signal of cable transmission from externally revealing.
4, described screen not only increases the shielding attenuation performance of product, make the audio-video signal of transmission not by the interference of external electromagnetic ripple, prevent leakage signal, reduce the attenuation constant value of product, also make product have good service behaviour, ensure that the high-frequency transmission performance of product excellence.
