Abstract

The utility model discloses an electric wire or cable of easy identification, which is formed by a conductor and an insulating layer. The insulating layer consists of a polyethylene inner layer, a physical foaming layer and a polyethylene outer layer or consists of a polyethylene inner layer, a solid layer and a polyethylene outer layer. Luminous dyeing mother materials with thermoplastic resin are arranged on the external surface of the insulating layer. By adopting the electric wire or cable of easy identification, since the luminous dyeing mother materials are added on the external surface of the insulating layer and the mother materials can emit light with different colors in dark places or at night, the construction worker can easily identify different cores and the work efficiency is improved.

Description

A kind of electric wire that is used to identify

Technical field

The utility model relates to a kind of electric wire, specially refers to a kind of electric wire that utilizes the iridescent masterbatch to identify.

Background technology

Existing cable insulation is general to be adopted the different core of different colouring discriminations or is printed on different colour codes or numeral is distinguished on core, though play the effect of sign, but condition is limited, when very dark at light or construct at night, during repair, want the different core of distinct color, the difficulty of distinguishing is very big, be prone to the problem of core wrong, in addition, the core of this sign had both influenced efficient in the work, greatly reduced the reliability in the engineering again, at present, the compound cable of the fluorescent material that has on the market and insulation glue-line is easy to infiltrate inner but the deficiency of this cable is silver-colored light powder, and the insulating properties of cable is had a negative impact.

Summary of the invention

The technical problems to be solved in the utility model is dim or avoid the core wrong when carrying on construction work at night, and influences operating efficiency.

In order to solve the problems of the technologies described above, the utility model provides a kind of electric wire that is used to identify, constitute by conductor and insulating barrier, insulating barrier combines by polyethylene inner layer skin, physical blowing layer and polyethylene sheath layer or by polyethylene inner layer skin, solid and polyethylene sheath layer, and the extexine of insulating barrier is provided with the noctilucence color concentrate of band thermoplastic resin.

The noctilucence color concentrate is blended in the polyolefine material of cable exodermis, and once extrudes by extruder; It is painted that cable insulation employing modes two-layer or three layers are carried out noctilucence.

When in the appearance cortex of insulating barrier, adding the noctilucence color concentrate of thermoplastic resin, it is reflective to guarantee that its masterbatch color and luster can take place under dim light, this color concentrate can send different colors, the operator is very dark or construct at night at light, during repair, can recognize the core of its different colours clearly, in addition, the fluorescence developing degree of color concentrate is to measure according to contained painted addition in this production material, when adding the masterbatch amount, carry out according to specification, reach as much as possible in a small amount, avoid the insulating properties of wire cable insulating layer is produced adverse influence.

Embodiment:

Embodiment one:

As Fig. 1,2,3,4, shown in 5 or 6, electric wire is made of conductor and insulating barrier, wherein insulating barrier is by polyethylene inner layer skin 2-1, physical blowing layer 2-2 and polyethylene sheath layer 2-3 or by polyethylene inner layer skin 2-1, solid and polyethylene sheath layer 2-3 combines, on the extexine 2-3 of insulating barrier, be provided with the noctilucence color concentrate 3 of band thermoplastic resin, when making the insulation three-decker, color concentrate 3 is blended in the exodermis 2-3 of insulating barrier, when producing, be provided with an extruder, this extruder is used to extrude endodermis 2-1, foaming layer 2-2 and the exodermis 2-3 that is mixed with color concentrate, in the temperature of setting thermoplastic resin noctilucence color concentrate 3 is blended in the polyolefine material of cable exodermis 2-3, and once extrude by extruder, when exodermis 2-3 adds color concentrate 3, observe its color and luster effect, mixed proportion how much determine the color and luster depth, also directly have influence on this color and luster and whether be issued to reflective effect in dim condition, in addition, the amount of adding when adding color concentrate 3 will be guaranteed as far as possible little, improves the insulating properties of its electric wire; After the completion of processing, the insulated wire strand of band look is made twisted pair wire group, star quad stranding line group, shielding star quad stranding line group is at last by user's the regulation and the cable core of the synthetic cable of standard group.

Embodiment two:

When insulating barrier did not adopt physical blowing, foaming layer was solid, adopt two-layer or three layers mode that cable insulation is carried out noctilucence is painted, other structures are identical with embodiment one.
