Abstract
The utility model discloses an improved RVV cable. The improved RVV cable comprises four main wire cables which are stranded by a plurality of copper core conductors, wherein the outer layers of the main wire cables are provided with PVC insulating layers respectively. The improved RVV cable is characterized in that the outer surfaces of the four main wire cables are connected together in a pairwise tangency manner, the improved RVV cable further comprises a PVC outer sheath arranged at the outermost layer of the cable, the inner wall of the PVC outer sheath is inwardly provided with four protruding parts used for filling peripheral gaps among the main wire cables in the circumferential direction, and the protruding parts are integrally shaped with the PVC outer sheath. As adoption of the technical solution disclosed by the utility model, the protruding parts and the PVC outer sheath of the improved RVV cable are integrally shaped, and the peripheral gaps among the main wire cables are filled tightly, thereby enabling the internal structure of the cable to be tight, being good in roundness, needing no additionally fillers, and reducing the production cost.
Description
Technical field
The utility model relates to field of cables, particularly a kind of follow-on RVV cable.
Background technology
Power cable is a traditional industry, the high strength of production safety process and high complexity, product diversification etc. propose higher requirement for the production management of the power cable of safety, strict in appearance from cable not only, requirement to cable inside is also stricter, traditional RVV cable takes wrapped formula to fill, the filler of cable inside and outer jacket are divided body formed, increased production cost.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of follow-on RVV cable that does not need outer packing just can make the cable compact internal structure, to solve the above-mentioned problem of mentioning for deficiency and the defective of existing RVV cable.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of follow-on RVV cable, comprise four by the stranded main cables that forms of some copper core conductors, described main cables skin is provided with the PVC insulating barrier, it is characterized in that, the outer surface of described four main cables is tangent linking together in twos, also comprise being arranged on the outermost PVC oversheath of cable, the inwall of described PVC oversheath circumferential interval inwardly is provided with everywhere in order to fill the protuberance in the peripheral space between described main cables, and described protuberance and described PVC oversheath are one-body molded.
Owing to having adopted above-mentioned technical scheme, protuberance of the present utility model and PVC oversheath are one-body molded, have closely filled the peripheral space between each main cables, make the cable compact internal structure, and roundness is good, need not outer packing, reduces production costs.
Description of drawings
Fig. 1 is the structural representation of a kind of follow-on RVV cable of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Figure 1, a kind of follow-on RVV cable comprises four main cables and outermost HR-70PVC restrictive coating 3, main cables is by stranded the forming of some copper core conductors 1, and the outer surface that the main cables skin is coated with 2, four main cables of JR-70PVC insulating barrier is tangent abutting against together in twos.
HR-70PVC restrictive coating 3 is coated on the outermost layer of this follow-on RVV cable by expressing technique, because employing expressing technique, integrated protuberance 4 is extruded at the circumferential interval of the inwall of HR-70PVC restrictive coating 3, protuberance 4 has intactly been filled the peripheral space between each main cables, make the cable compact internal structure, roundness is good, need not outer packing, reduces production costs.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; 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 changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
