Abstract
The utility model relates to a combined communication cable for a coal mine, which relates to the technical field of cables and is characterized by comprising a plurality of conductors, wherein a polyethylene insulating layer is arranged at the outer part of each conductor, a woven shielding layer is arranged at the outer part of the polyethylene insulating layer, a belting layer is arranged at the outer part of the woven shielding layer, a steel-wire armoring layer is arranged at the outer part of the belting layer, and a jacketing layer is arranged at the outer part of the steel-wire armoring layer. The combined communication cable has the advantages of better bending softness, longer service life than that of an ordinary cable, wider use-temperature range, higher use frequency, lower attenuation, good overall-shielding performance and high reliability.
Description
Technical field
The utility model relates to the cable technology field, is specifically related to a kind of colliery and uses the combined communication cable.
Background technology
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all above 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes first in the world electric wire producing country.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.China's economic growth continuously and healthily; For cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight; Reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry lets the world regard with special esteem.Along with the continuous expansion of industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.The occasion that use with signal-transmitting cable in the colliery is more abominable, and than common cable, the requirement of strength of this type cable is very high, needs corrosion-resistant, rub resistance, acid-fast alkali-proof performance all very strong, also needs stronger stretch-proof performance.Owing to accident occurs through regular meeting in the colliery, cause the cable can't transmission signals, at this moment need develop some subsequent use performances of cable.
The utility model content
The utility model technical problem to be solved is to provide a kind of reasonable in design, and the combined communication cable is used in the colliery of economy and durability.
The utility model technical problem to be solved adopts following technical scheme to realize,
The combined communication cable is used in a kind of colliery; It is characterized in that: comprise some conductors; Every conductor outside is provided with polyethylene layer, is provided with woven shield in said polyethylene layer outside, is provided with belting layer in said woven shield outside; Be provided with the wire armoring layer in said belting layer outside, be provided with restrictive coating in said wire armoring layer outside.
Described restrictive coating is fire-retardant adjudicate two cases together ethene restrictive coating.
The beneficial effect of the utility model is: the utlity model has crooked preferably softness, than common cable long service life, the serviceability temperature scope is wideer, frequency of utilization is higher, decay is lower, the bulk shielding performance is good, reliability is high.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the combined communication cable is used in a kind of colliery, comprises some conductors 1; Every conductor 1 outside is provided with polyethylene layer 2; Be provided with woven shield 3 in polyethylene layer 2 outsides, be provided with belting layer 4, be provided with wire armoring layer 5 in belting layer 4 outsides in woven shield 3 outsides; Be provided with restrictive coating 6 in wire armoring layer 5 outside, restrictive coating 6 is fire-retardant adjudicate two cases together ethene restrictive coating.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
