Abstract
The present invention discloses a pre-branch cable. The cable comprises a cable body which has a section with a circle structure. The cable body includes a main cable, branch cables and an insulation layer coated at the outer of the main cable and the branch cables. The main cable is arranged at the center position of the cable body, the branch cables are arranged around the main cable, a plurality of long releasing grooves are arranged at the periphery of the insulation layer, and the releasing grooves are located between adjacent branch cables and are extended out of the main cable. The pre-branch cable adds releasing grooves which are located between adjacent branch cables and are extended out of the main cable, the releasing grooves are employed to separate the branch cables from the main cable, and the pre-branch cable is convenient in on-site construction and good in insulation performance, waterproof performance and fireproof performance.
Description
Technical field
The present invention relates to the technical field of electric wire, particularly relate to a kind of pre-branched cable line.
Background technology
Along with the strong growth of Chinese national economy, various capital constructions, capital construction, the speed of development of real estate adds
Hurry up, with power cable as in various buildings, facility for backbone be inevitable.Therefore, from construction unit, designing unit, hold
Found a capital unit in charge of construction seeking that more advanced, more cost effective, performance is more superior, to take the useful space less, execute
What the work cycle was shorter supplies power distribution construction technology and method.The most just under the conditions of such history environment, pre-branched cable is stepped on greatly
Step ground enters China's architectural electricity stage.
A kind of pre-branched cable method of tradition is at the scene, the oversheath on one section of leader cable of strip off, insulating barrier, then will divide
Branch cable strip off oversheath, the end of insulating barrier are connected on the conductor of leader cable.With hydraulic tongs or alternate manner, pass through conductor
Connector is attached, and finally processes with epoxy resin or other insulant encapsulatings.And the deficiencies in the prior art exist
In: for above-described component on site construction method, its difficulty is big, technology requires height, there is also dielectric strength simultaneously and is difficult to ensure that,
Reliability, concordance are poor.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of pre-branched cable line, has site operation convenience, insulation
Performance, water resistance are good, fire resistance is good.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of pre-branched cable line,
Including cable body, the cross section of described cable body is circular configuration, and described cable body includes main cable, branch's electricity
Cable and be wrapped in the insulating barrier outside main cable and branch cable, described main cable is arranged on the center of cable body
Position, described branch cable is separately positioned on the surrounding of main cable, the periphery of described insulating barrier is provided with several
The release groove of strip, described release groove is between adjacent branch cable and extends to the outside of main cable.
In a preferred embodiment of the present invention, described main cable is single, multicore or coil buckling type multicore cable.
In a preferred embodiment of the present invention, described branch cable is single-core cable.
In a preferred embodiment of the present invention, the cross section of described release groove is triangular structure.
In a preferred embodiment of the present invention, described insulating barrier uses polrvinyl chloride molding insulation.
The invention has the beneficial effects as follows: the pre-branched cable line of the present invention, being additionally arranged release groove, release groove is positioned at adjacent
Between branch cable and extend to the outside of main cable, take hands to tear off type groove and just can be separated with main cable by branch cable
Open, there are site operation convenience, insulating properties, water resistance is good, fire resistance is good.
Accompanying drawing explanation
For the technical scheme being illustrated more clearly that in the embodiment of the present invention, in embodiment being described below required for make
Accompanying drawing be briefly described, it should be apparent that, below describe in accompanying drawing be only some embodiments of the present invention, for
From the point of view of those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other according to these accompanying drawings
Accompanying drawing, wherein:
Fig. 1 is the cross section structure schematic diagram of a preferred embodiment of pre-branched cable line of the present invention；
Reference is as follows: 1, cable body, 11, main cable, 12, branch cable, 13, insulating barrier, 14, release groove.
Detailed description of the invention
Technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described enforcement
Example is only a part of embodiment of the present invention rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiments that technical staff is obtained under not making creative work premise, broadly fall into the model of present invention protection
Enclose.
As it is shown in figure 1, the embodiment of the present invention includes:
A kind of pre-branched cable line, including cable body 1, the cross section of described cable body 1 is circular configuration, described cable
Body 1 includes main cable 11, branch cable 12 and is wrapped in the insulating barrier 13 outside main cable 11 and branch cable 12,
Described main cable 11 is arranged on the center of cable body 1, and described branch cable 12 is separately positioned on main cable
The surrounding of 11, the periphery of described insulating barrier 13 is provided with the release groove 14 of several strips, described release groove 14
Between adjacent branch cable 12 and extend to the outside of main cable 11.
In above-mentioned, described main cable 11 is single, multicore or coil buckling type multicore cable；Described branch cable 12 is
Single-core cable.
Further, the cross section of described release groove is triangular structure, and taking hands to tear off type groove just can be by branch cable
Separate with main cable.
In the present embodiment, described insulating barrier 13 uses polrvinyl chloride molding insulation, and insulating properties, water resistance are good, resistance to
Fire performance is good.
In sum, the pre-branched cable line of the present invention, it is additionally arranged release groove, release groove 14 is positioned at adjacent branch cable
Between 12 and extend to the outside of main cable 11, take hands to tear off type groove and just can be separated with main cable 11 by branch cable 12
Open, there are site operation convenience, insulating properties, water resistance is good, fire resistance is good.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every present invention of utilization says
Equivalent structure or equivalence flow process that bright book content is made convert, or are directly or indirectly used in other relevant technical field, all
In like manner it is included in the scope of patent protection of the present invention.
