Abstract

The invention provides a compact type two-core compound cable with control line core pairs. The compact type two-core compound cable with the control line core pairs comprises phase line cores, ground wire cores, the control line core pairs and a sheath, wherein the ground wire cores are a plurality of insulating single conductors, the ground wire cores and at least one control line core pair form an arc section and are concentrically and evenly distributed on the outer circumference of the phase line cores, and the sheath is arranged at the outermost layer in an extrusion mode. The ground wire cores and control line cores are concentrically and evenly distributed outside the phase line cores, so that the phase line cores for transmitting electricity are located at the innermost layer and play a role similar to wire armoring, the phase line cores can be well protected, and damage to the phase line cores caused by external force is effectively relieved.

Description

A kind of with controlling the right compact two core composite cables of core

Technical field

The present invention relates to power cable field, specifically a kind of with controlling the right compact two 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.

The band of prior art is controlled two core composite cables of core, and structure is that to be extruded with the circular core of insulation stranded by controlling cable core conventionally, or semicircle, segment conductor-core stranded after with to control cable core stranded.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 two 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 two 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 two 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, in order to solve the problem of prior art, provides a kind of signal to disturb little, simultaneously transferring electric power and control signal, winding displacement more rationally, closely, compact conformation, external diameter is little, and the band that is easy to processing and convenient construction is controlled the right compact two core composite cables of core.

The present invention includes phase core, core, control core to, sheath, the single conductor that described ground core is some tape insulations, with at least one pair of control core to together with, each becomes a segmental arc, is distributed on one heart on phase core excircle, outermost layer is extruded with sheath.

Described control core, to comprising two control cores that directly drag, is surrounded with metal screen layer outward at control core.

After the outer wrapped metal screen layer of described phase core, be surrounded with band, or be extruded with thin sheath.

Described metal screen layer is metal knitted screen.

Described ground core single conductor is with to control core highly identical to 3, equidistant gap arrangement or to be covered with phase core peripheral.

Beneficial effect of the present invention is:

1, simultaneously transferring electric power and control signal, and have mutually metal screen layer to shield, independent mutually, signal disturbs little;

2, phase core, core all directly drag, saved packing material and band, reduced the waste of material of stranded increase length, alleviated weight.

3, compared with prior art, winding displacement more rationally, closely, has reduced to lay space, easy construction.

4, 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 invention structural representation.

Embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

As shown in Figure 1, the present invention includes phase core 2, core 1, control core to 3, sheath 4, it is characterized in that: described ground core 1 is the single conductor of some tape insulations, control core to together with 3 with at least one pair of, each becomes a segmental arc, be distributed on one heart on phase core 2 excircles, outermost layer is extruded with sheath 4.

Described control core comprises two control cores that directly drag to 3, at control core, is surrounded with metal screen layer outward.

After the outer wrapped metal screen layer of described phase core 2, be surrounded with band, or be extruded with thin sheath.

Described metal screen layer is metal knitted screen.

Core 1 single conductor in described ground is with to control core highly identical to 3, equidistant gap arrangement or to be covered with phase core peripheral.

The present invention can for phase line core, core cross-sectional sizes equate etc. two cored structures, also can equate for phase line core cross-sectional sizes " small one and large one " structure that core cross section, ground is less.

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.
