Abstract
The invention discloses a cable for industrial appliance equipment. The cable comprises a conductor, a pair twist group and an insulation layer, wherein the insulation layer made of crosslinked polyethylene is wound and cladded onto the conductor for forming conducting cores, the two conducting cores are twisted into the pair twist group, a polyurethane inner cladding belt layer is wound and cladded outside the pair twist group, a silver plating copper wire shielding layer is arranged outside the inner cladding belt layer, an inner lining layer is arranged outside the shielding layer for forming cable cores, a polyurethane outer cladding belt layer is wound and cladded after the three cable cores are twisted, and a total shielding layer and a sheath layer are also sequentially arranged outside the outer cladding belt layer. The cable has the advantages that the structure is compact, the cable is provided with a sub shielding layer and a total shielding layer, the shielding layers are woven by tin plating copper wires, and the external interference can be effectively prevented. Meanwhile, the insulation layer adopts materials of crosslinked polyethylene with the insulation performance, the work capacitance can be favorably reduced, the insulation resistance can be favorably improved, and the voltage withstanding characteristic is improved.
Description
technical field
The present invention relates to compensating cable field, relate in particular to
oneplant industrial electrical equipment and establish cable in stock.
background technology
Cable is normally by the cable of several or at least two every group stranded similar ropes that form of several groups of wires, mutually insulated between every group of wire, and be often twisted into round Yi Gen center, whole outside is surrounded by the cover layer of high-insulation.Cable has power cable, control cables, compensating cable, shielded type cable, high-temperature cable, computer cable, signal cable, coaxial cable, fire-resisting cable, shipboard cable, aluminium alloy cable etc.They are all made up of sub-thread or stranded conductor and insulating barrier, are used for connecting circuit, electrical equipment etc.
At present, in the many high temperature of industry places such as oil, chemical industry, smeltings, require supporting with it various products to adapt with environment for use temperature, the long-term safety stable operation of guarantee equipment like this.The common compensating cable using in these high temperature places, can not meet the requirement of environment for use.
summary of the invention
The invention provides confession
oneplant industrial electrical equipment and establish cable in stock, solved the problem of cable due to electric spark and thermal effect initiation explosion hazard gases blast and cable selfcapacity and distributed inductance.
The following a kind of industrial electrical equipment of the solution of the present invention is established cable in stock, comprise conductor, pair twist group, insulating barrier, the insulating barrier that the wrapped crosslinked polyethylene of described conductor is made forms leads core, lead core for two and be twisted into pair twist group, belting layer in the outer wrapped polyurethane of described pair twist group, described interior belting layer arranges silver-gilt copper wire screen outward, described screen arranges inner covering outward and forms core, three outer belting layers of the stranded rear wrapped polyurethane of core, the outer belting layer of institute's art also arranges total screen, restrictive coating outward successively; Described total screen adopts tinned copper wire braiding, and described restrictive coating adopts low-smoke halide-free fireproof composite polyolefine material.
Further, described conductor adopts stranded the forming of 10-20 thigh copper wire, and described conductor cross-sectional area is 0.5-15mm
2.
Further, described screen and total shielding thickness are 0.5-15mm
2.
Compact conformation of the present invention, cable has sub-shield and total screen, and shielding adopts tinned copper wire braiding, and count reaches more than 90%, can effectively prevent external interference.Meanwhile, it is insulation that insulating barrier adopts material crosslinked polyethylene, contributes to reduce mutual capacitance, improves insulation resistance, improves voltage-resistent characteristic, also has good fire resistance simultaneously; Cable also has low electric capacity and low inductance, cable itself with electric charge to lack, be difficult for produce electric spark; Also there is anti-explosion safety performance.
brief description of the drawings
Fig. 1 is structural representation of the present invention.
embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
A kind of industrial electrical equipment is established cable in stock, comprise conductor 1, pair twist group, insulating barrier, the insulating barrier 2 that the described wrapped crosslinked polyethylene of conductor 1 is made forms leads core, lead core for two and be twisted into pair twist group, belting layer 3 in the outer wrapped polyurethane of described pair twist group, the outer silver-gilt copper wire screen 4 that arranges of described interior belting layer 3, the outer inner covering 5 that arranges of described screen 4 forms core, three outer belting layers 6 of the stranded rear wrapped polyurethane of core, outer total screen 7, the restrictive coating 8 of also arranging successively of outer belting layer 6 of institute's art; Described total screen 7 adopts tinned copper wire braiding, and described restrictive coating 8 adopts low-smoke halide-free fireproof composite polyolefine material.
Described conductor 1 adopts stranded the forming of 10-20 thigh copper wire, and described conductor 1 cross-sectional area is 0.5-15mm
2.Described screen 4 and total screen 7 thickness are 0.5-15mm
2.
Although above the specific embodiment of the present invention has been given to describe in detail and explanation; but what should indicate is; we can carry out various equivalences to above-mentioned execution mode according to conception of the present invention and change and amendment; when its function producing does not exceed spiritual that specification and accompanying drawing contain yet, all should be within protection scope of the present invention.
