Abstract
The utility model discloses a soft power cable having a butyronityile compound insulating layer and a butyronityile compound sheath, comprising three conductor groups parallelly arranged, wherein each of the three conductor groups is formed by twisting a plurality of conductors into a strand, the outer side of strand is sequentially coated with an insulating layer, a wrapping layer and an inner lining layer, linking belts are arranged between two inner lining layers, the two ends of each linking belt are respectively connected to the outer walls of the inner lining layers, each linking belt is a flat belt-shaped connecting rope, the outside of each of the three conductor groups each coated with an inner lining layer is coated with a sheath layer, and the cross section of the sheath layer is flat. Since the connecting ropes are arranged between the inner lining layers, the stretch-proof property of the cable is enhanced, and the compactness of the structure is increased; and the insulating layer and the sheath layer are formed by extruding polyvinyl chloride compound flame-retardant elastomers, the flexing resistance is strong, and the service life is long.
Description
Technical field:
The utility model relates to the power cable field, relates in particular to a kind of butyronitrile compound insulation and the soft power cable of sheath.
Background technology:
Power set are operated under the condition of high temperature, because the production environment temperature is high, and cable insulation easy ageing, the useful life of having reduced cable design; Improve cable and changed frequency, in the production, cable running time under the time limit of normally using according to cable design in cable useful life and the varying environment, definite according to experience; For fear of the cable accident of bursting apart, increase coefficient of safety, cable value in useful life is less; Replacement cycle is short, because power set need a large amount of power cable and control cable, it is very high to change frequency; Changing the power set cable needs great amount of manpower, thereby shortens the replacement cycle operation, has increased cable cost; Waste manpower, increased the maintenance off-time, reduced production efficiency.
Too early bending failure of conductor and fracture just took place in one month in have even less than, how to improve anti-song property level, the stretch-proof performance of such cable, and how carrying out material chosen and architecture advances is the emphasis of industry work.
The insulating barrier of the utility model, restrictive coating adopt butyronitrile polyvinyl chloride composite flame-proof elastomer to extrude and process, and anti-Qu Xingneng is stronger, long service life; Be provided with connection cord between the inner covering of cable simultaneously, strengthened the stretch-proof performance of cable, the compactedness of structure.
The utility model content:
To the prior art problem; The purpose of the utility model provides a kind of butyronitrile compound insulation and the soft power cable of sheath, is applicable to the electric power transfer that ac rated voltage 0.6/1kv and following requirement are frequently mobile, occasion oil resistant is used as power device or portable lighting.
The technical scheme of the utility model is following:
Insulation of butyronitrile compound and the soft power cable of sheath; Comprise three conductor groups, the parallel placement arranged side by side of described three conductor groups, described three conductor groups are respectively by the stranded bunchy of several conductors; The outside is enclosed with insulating barrier, belting layer, inner covering successively behind the bunchy; It is characterized in that: be provided with relatedly between the described inner covering, related two ends link to each other with the inner covering outer wall respectively, described related be the banded connection cord of flat; Three conductor groups of parcel inner covering are wrapped with restrictive coating, and described restrictive coating cross section is a pancake.
Described butyronitrile compound insulation and the soft power cable of sheath, it is characterized in that: the expressing technique of described insulating barrier, restrictive coating adopts squash type, and material is adopted as butyronitrile polyvinyl chloride composite flame-proof elastomer.
Described butyronitrile compound insulation and the soft power cable of sheath, it is characterized in that: the outer wall of described several conductors is provided with tin coating.
The utility model has the advantages that:
Be provided with connection cord between the utility model inner covering, strengthened the stretch-proof performance of cable, the compactedness of structure; Insulating barrier, restrictive coating adopt butyronitrile polyvinyl chloride composite flame-proof elastomer to extrude and process, and anti-Qu Xingneng is stronger, long service life.
Description of drawings:
Fig. 1 is the structural representation of the utility model.
Embodiment:
Insulation of butyronitrile compound and the soft power cable of sheath comprise the 1 parallel placement arranged side by side of 1, three conductor group of three conductor groups; Three conductor groups 1 are respectively by several conductor 2 stranded bunchys, and the outside is enclosed with insulating barrier 3, belting layer 4, inner covering 5 successively behind the bunchy, is provided with related 6 between the inner covering 5; Related 6 two ends link to each other with inner covering 5 outer walls respectively, and related 6 is the banded connection cord of flat, and three conductor groups of parcel inner covering 5 are wrapped with restrictive coating 7; Restrictive coating 7 cross sections are pancake; The expressing technique of insulating barrier 3, restrictive coating 7 adopts squash type, and material is adopted as butyronitrile polyvinyl chloride composite flame-proof elastomer, and the outer wall of several conductors 2 is provided with tin coating.
