Abstract
The utility model discloses a copper clad aluminium insulated cable, including wire and the insulation protective layer of cladding in the wire outside who is located the center, the wire be the stranded conductor that many copper clad aluminum conductors are constituteed, many copper clad aluminum conductors are the closely knit structure of sticising each other, the many distributions of copper clad aluminum conductor on the cross section are a copper clad aluminum conductor and are located center department, and all the other copper clad aluminum conductors distribute at the periphery to it is the even number to be located peripheral copper clad aluminum conductor number. Because the inside copper clad aluminum conductor that is to be the closely knit structure of sticising, eliminated the clearance between each wire, reduced the external diameter of cable, do not influencing promptly that the cross -section reduces under the electrically conductive condition, the cable external diameter can reduce 8%, and outside protective layer NULL reduces greatly, has reduced manufacturing cost.
Description
Technical field
The utility model relates to a kind of wire, particularly a kind of copper cover aluminum insulated cable.
Background technology
Insulated cable is widely used in every profession and trade, and the existing construction of cable is the twisted wire be made up of stranded conductor in centre, and there is the insulating barrier of elastomeric material in outside, i.e. protective layer, wherein the existing copper aluminium matter that also has of wire.No matter which kind of, all exist a problem, namely each stock wire has certain gap to exist each other, and cause the global sections of insulated cable long-pending comparatively large, peripheral insulating layer material consumption increases thereupon.
Summary of the invention
The purpose of this utility model is to provide tight between a kind of compact conformation, each stock wire, reduces sectional area, transport, easy for installation, save the copper cover aluminum insulated cable of insulating material, overcome the deficiencies in the prior art.
Copper cover aluminum insulated cable of the present utility model, comprises the wire being positioned at center and the insulating protective layer be coated on outside wire, and described wire is the twisted wire of many copper cladding aluminum conductor compositions, and many copper cladding aluminum conductors press structure in closely knit mutually; The be distributed as copper cladding aluminum conductor of many copper cladding aluminum conductors on cross section is positioned at center, and all the other copper cladding aluminum conductors are distributed in periphery, and the copper cladding aluminum conductor number being positioned at periphery is even number.
Copper cover aluminum insulated cable of the present utility model, many wherein said copper cladding aluminum conductors are seven, and the circumferential distribution of the copper cladding aluminum conductor of center has six roots of sensation copper cladding aluminum conductor; The sectional area that every root is positioned at the copper cladding aluminum conductor of periphery is less than the sectional area of the copper cladding aluminum conductor of center.
Copper cover aluminum insulated cable of the present utility model, is provided with metal screen layer in wherein said protective layer, between wire and metal screen layer, is provided with insulating barrier.
Copper cover aluminum insulated cable of the present utility model; because inside is copper cladding aluminum conductor; and press structure in closely knit; gap is eliminated between each wire; reduce the external diameter of cable, namely reduce at the situation lower section not affecting conduction, outer diameter of cable can reduce 8%; exterior cover sheets material usage reduces greatly, reduces manufacturing cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of cable section in the utility model embodiment.
Embodiment
As shown in Figure 1: copper cover aluminum insulated cable of the present utility model, the wire being positioned at center and the insulating protective layer 1 be coated on outside wire is comprised.This wire is the twisted wire that many copper cladding aluminum conductors 4 form, many copper cladding aluminum conductors 4 press structure in closely knit mutually, pressing structure is adopt wire rod impacted process to be compressed by each stock copper cladding aluminum conductor, adjacent copper cladding aluminum conductor is compressed mutually, very close to each other each other, forming surface contact between adjacent copper cladding aluminum conductor, the cross sectional shape of the copper cladding aluminum conductor after compression changes, all in special-shaped state.
The many distributions of copper cladding aluminum conductor 4 on cross section are as follows: a copper cladding aluminum conductor is positioned at center, and all the other copper cladding aluminum conductors are distributed in periphery, and the copper cladding aluminum conductor number being positioned at periphery is even number.In the utility model embodiment, copper cladding aluminum conductor 4 selects seven, and the circumferential distribution of the copper cladding aluminum conductor centrally located has six roots of sensation copper cladding aluminum conductor.The sectional area that every root is positioned at the copper cladding aluminum conductor of periphery is less than the sectional area of the copper cladding aluminum conductor of center.Be provided with the screen 2 of metal wire knitted net materials in protective layer 1, between wire and metal screen layer 2, be provided with the insulating barrier 3 of elastomeric material.
Claims (3)
1. a copper cover aluminum insulated cable, comprise the wire being positioned at center and the insulating protective layer (1) be coated on outside wire, it is characterized in that: described wire is the twisted wire that many copper cladding aluminum conductors (4) form, many copper cladding aluminum conductors (4) press structure in closely knit mutually; The be distributed as copper cladding aluminum conductor of many copper cladding aluminum conductors (4) on cross section is positioned at center, and all the other copper cladding aluminum conductors are distributed in periphery, and the copper cladding aluminum conductor number being positioned at periphery is even number.
2. copper cover aluminum insulated cable according to claim 1, is characterized in that: described many copper cladding aluminum conductors (4) are seven, and the circumferential distribution of the copper cladding aluminum conductor of center has six roots of sensation copper cladding aluminum conductor; The sectional area that every root is positioned at the copper cladding aluminum conductor of periphery is less than the sectional area of the copper cladding aluminum conductor of center.
3. copper cover aluminum insulated cable according to claim 2, is characterized in that: be provided with metal screen layer (2) in described protective layer (1), be provided with insulating barrier (3) between wire and metal screen layer (2).
