Abstract

The invention discloses a three-core composite cable with control wire core pairs. The three-core composite cable with the control wire core pairs comprises a cable core, wherein the cable core is formed by a phase wire core in the center and a wire core layer in an intertwist mode, the wire core layer is wrapped on the phase wire core, an outer sheath is wrapped on the cable core in a pressing mode, the wire core layer is composed of a plurality of neutral wire cores, a plurality of ground wire cores and at least one pair of control wire cores, and the neutral wire cores, the ground wire cores and the control wire cores are arranged outside the phase wire core in an abreast and concentric mode. According to the three-core composite cable with the control wire core pairs, signal interference is low, electric power signals and control signals can be transmitted at the same time, wire arrangement is more reasonable and more compact, the structure is compact, the outer diameter is small, processing is easy, and construction is convenient.

Description

A kind of with controlling three right core composite cables of core

Technical field

The invention belongs to electric wire field, particularly a kind of with controlling three right core composite cables of core.

Background technology

Develop rapidly along with the universal and information industry of computer technology, intelligent residential areaization has become the development trend of modern architecture, by the comprehensive wiring system that formed by composite cable etc. the communication in intelligent construction, computer and various device and facility, include under certain conditions comprehensive wiring system in, be interconnected to form complete supporting integral body, to realize highly intelligentized requirement.

Three core composite cables of the band control core of prior art, structure is stranded by controlling cable core and three circular cores that are extruded with insulation conventionally, or three segment conductor-cores are stranded rear stranded with control cable core.Three-core cable core comprises third-class core that three cross-sectional area of conductor are identical or two cross-sectional area of conductor are large, a 2+1 core that cross-sectional area of conductor is little.No matter be the stranded of which kind of form, core gap is larger, not only make cable roundness poor, and extrude and the process such as construction in easily loose, and core easily channels bit, conventionally add packing material stranded together, and skin need be tightened with band when stranded for this reason, after stranded or stranding, extrude again sheath.This structure band is controlled three core composite cables of cable core, and not only cable core poor stability, and material usage is large, has also increased cable weight and cost.As adopt three stranded segment conductor-core structures, although cable core stability improves, core is processed into sector structure, processes round core complicated, needs strict control segment angle and fan-shaped height, and easily occurs the phenomenons such as in uneven thickness, insulating barrier splits; Secondly, no matter be three core composite cables of the band control cable core of which kind of stranded form, lay configuration, increases actual core length, wastes material, increases weight, and cable cost increases; Again, this structure also makes the outside diameter of cable larger, especially large specification cable, and large external diameter has not only increased manufacture, transportation difficulty, and takies that to lay space large.Besides, the composite cable power core of structure is larger to the electromagnetic interference of control core conventionally.

Summary of the invention

The present invention overcomes the shortcoming that prior art exists, and provides a kind of signal to disturb little, transferring electric power and control signal simultaneously, winding displacement more rationally, closely, compact conformation, external diameter is little, is easy to the three right core composite cables of band control core of processing and convenient construction.

Disclosed by the inventionly a kind ofly with controlling three right core composite cables of core, comprise cable core, cable core is by phase core and wrapped stranded the forming of core layer outside phase core at center, and cable core extrudes oversheath outward; Described core layer by be arranged in one heart side by side some neutral cores outside phase core, core and at least one pair of control core to forming.

Further improve, the phase conductor that described phase core consists of some monofilament and wrapped insulating barrier in phase conductor form.

Further improve, described control core is to controlling cores, wrappedly control the metal knitted screen outside cores and the thin sheath being extruded in outside metal knitted screen forms at 2 by 2 that directly drag.

Further improve, described neutral core, the diameter of core identical or different, homonymies that both positions and control core are right or be positioned at not homonymy.

Further improve, this cable be phase core, neutral core, core cross-sectional sizes equate etc. three-core structure or equate " small one and large one " structure less with core cross section, ground for phase core, neutral core cross-sectional sizes.

Beneficial effect of the present invention is:

Of the present invention a kind of with controlling three right core composite cables of core, transferring electric power and control signal simultaneously, and have mutually metal screen layer to shield, independent mutually, signal disturbs little; Phase core, core all directly drag, saved packing material and band, reduced the waste of material of stranded increase length, alleviated weight.Compared with prior art, winding displacement more rationally, closely, has reduced to lay space, easy construction.Neutral core, core with control core to together with concentric being distributed on outside phase core; make the phase core of bearing electric power transfer be positioned at innermost layer; not only can play similar steel wire armoured effect, can play a very good protection to phase cable core, effectively alleviate and damaged by external force.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Embodiment

Below in conjunction with accompanying drawing, embodiments of the present invention are elaborated.

As shown in Figure 1, a kind ofly with controlling three right core composite cables of core, comprise cable core, cable core is by phase core 1 and wrapped stranded the forming of core layer 2 outside phase core 1 at center, and cable core extrudes oversheath 3 outward; Described core layer 1 is comprised of 64, the 4 ground cores 5 of 3 neutral cores and the 2 pairs of control cores that are arranged in one heart side by side outside phase core 1.

The phase conductor 8 that described phase core 1 consists of some monofilament 7 and wrapped insulating barrier 9 in phase conductor 8 form.

Described control core is controlled cores 10, wrappedly at 2, is controlled the metal knitted screen 11 outside cores 10 and the thin sheath 12 being extruded in outside metal knitted screen 11 forms by directly drag 26.

The concrete application approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
