Abstract
The utility model relates to a novel communication cable for a control cabinet. The communication cable comprises multiple wire core conductors, insulating layers and an air pipe, wherein each wire core conductor is wrapped by one insulating layer; the multiple wire core conductors are uniformly distributed around the air pipe; and the communication cable is sequentially provided with a signal shielding layer, an isolation layer, a water-blocking layer and a sheath layer from the outside of the insulating layers. The novel communication cable with the above structure meets requirements of simple structure and safe use, and also has significantly improved heat radiation performance, and thus work performance and service life of the cable are substantially improved.
Description
Technical field
The utility model relates to a kind of Novel control cabinet telecommunication cable.
Background technology
At present, control cubicle in commercial Application is because its internal structure is complicated, thermal diffusivity is poor, therefore than outside control cubicle can by the many kinds of measures such as air-conditioning or blower fan concerning telecommunication cable carry out cooling, to the cooling requirement that still can not meet control cubicle circuit far away of the ventilation of the telecommunication cable of control cubicle inside, especially under the long playing condition of control cubicle, because heat dispersion is bad, just more easily cause the excess Temperature of control cubicle circuit, thereby affect service behaviour and the useful life of telecommunication cable, even when serious, can cause fire.
Utility model content
For overcoming above the deficiencies in the prior art, the technical problems to be solved in the utility model is to provide a kind of safety simple in structure, practical, and transmittability is strong, the Novel control cabinet telecommunication cable of perfect heat-dissipating.
The technical solution of the utility model is:
A kind of Novel control cabinet telecommunication cable, comprise a plurality of core conductors and be wrapped in the insulating barrier outside each core conductor, and be located at the breather pipe between a plurality of core conductors, and a plurality of core conductors are evenly distributed on around breather pipe, this telecommunication cable is outwards also provided with signal shielding layer, separator, water blocking layer and restrictive coating successively from insulating barrier.
Above-mentioned Novel control cabinet telecommunication cable, the shape of cross section that is wherein wrapped in the insulating barrier outside each core conductor is fan ring, and the fan ring of insulating barrier inner side and breather pipe snug fit.
Above-mentioned Novel control cabinet telecommunication cable, the ratio of the internal diameter of its Center Vent tube and core conductor diameter is 2:1.
Above-mentioned Novel control cabinet telecommunication cable, is wherein provided with ventilating hole channel in restrictive coating, and the shape of cross section of ventilating hole channel is fan ring.
Above-mentioned Novel control cabinet telecommunication cable, the material of its Center Vent tube is high density polyethylene (HDPE).
The beneficial effects of the utility model are:
1, the utility model is by adopting the structures such as breather pipe, signal shielding layer, separator, water blocking layer and restrictive coating, both met simple in structure, use safe requirement, significantly improved again the heat dispersion of telecommunication cable, and then greatly improved service behaviour and the useful life of cable;
2, the utility model is by being further designed to the shape of cross section that is wrapped in the insulating barrier outside each core conductor fan ring, thereby make can fit more closely between breather pipe and insulating barrier, when by breather pipe, cable being carried out when cooling, can further improve the cooling performance of breather pipe;
3, the utility model is by be further also provided with ventilating hole channel in restrictive coating, thereby increased space and the area of heat radiation, and then further improved the heat dispersion of telecommunication cable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the cross section structure schematic diagram of telecommunication cable for Novel control cabinet;
Fig. 2 is that the cross sectional shape of insulating barrier is the telecommunication cable cross section structure schematic diagram while being provided with ventilating hole channel in fan ring and restrictive coating.
In figure: breather pipe 1, core conductor 2, insulating barrier 3, signal shielding layer 4, separator 5, water blocking layer 6, restrictive coating 7, ventilating hole channel 8.
Embodiment
As shown in Figure 1, a kind of Novel control cabinet telecommunication cable, comprise a plurality of core conductors 2 and be wrapped in the insulating barrier 3 outside core conductor 2, and be located at the breather pipe 1 between a plurality of core conductors 2, and a plurality of core conductors 2 are evenly distributed on around breather pipe 1, this telecommunication cable is outwards also provided with signal shielding layer 4, separator 5, water blocking layer 6 and restrictive coating 7 successively from insulating barrier 3.
In the selection of material, breather pipe 1 can adopt by high density polyethylene (HDPE) and extrude the tubular body forming, and has the effect of ventilation and heat; Core conductor 2 can adopt copper purity to be greater than the soft copper silk that 99.95% cathode copper processes, and its elongation at break is greater than 30%, has certain pliability; Insulating barrier 3 adopts environment-friendly polyvinyl chloride CABLE MATERIALS, reaches the effect of environmental protection; Signal shielding layer 4 adopts proof copper-wire braided layer, and adopts the braiding of annealed copper silk, and count is controlled between 80-85%, has guaranteed the laser propagation effect of signal; Separator 5 adopts low-smoke halogen-free material to extrude and forms, and has the effect of environmental protection flame retardant; Water blocking layer 6 adopts glass fiber yarn braiding to form, and has fire-resistant, wear-resisting effect; Restrictive coating 7 adopts low-smoke halogen-free polyolefin, has the effect of environmental protection, low cigarette.By adopting said structure and material, both met simple in structure, use safe requirement, significantly improved again the heat dispersion of telecommunication cable, thereby greatly improved service behaviour and the useful life of cable.
As a kind of, preferably as shown in Figure 2, for above-mentioned Novel control cabinet telecommunication cable, be wherein wrapped in the shape of cross section of the insulating barrier 3 outside core conductor 2 for fanning ring, and the fan ring of insulating barrier 3 inner side and breather pipe 1 snug fit.Like this, can make the position between core conductor 2 and insulating barrier 3 interfix, in use do not make the random changing of the relative positions of core conductor 2 or winding, and by 1 pair of telecommunication cable of breather pipe, undertaken when cooling, again because insulating barrier 3 and breather pipe 1 form and are close in large area more, thereby can further improve the cooling performance of breather pipe 1.And, in restrictive coating 7, also can be provided with shape of cross section for the ventilating hole channel 8 of fan ring, can increase like this space and the area of cable heat radiation, and then further improve the heat dispersion of telecommunication cable.
As further preferred, the ratio of the internal diameter of telecommunication cable Center Vent tube 1 and core conductor 2 diameters can be designed to 2:1, fully to guarantee that breather pipe 1 has enough ventilation spaces, thereby effectively its core conductor 2 and insulating barrier 3 is around dispelled the heat.
By reference to the accompanying drawings the preferred embodiment of the utility model and embodiment are explained in detail above, but the utility model is not limited to the above-described embodiment and examples, in the ken possessing those skilled in the art, can also make without departing from the concept of the premise utility various variations.
