Description

Anti-aging aluminium alloy coaxial-type two core cable

One, technical field:

The utility model relates to a kind of two core cables, more particularly to a kind of anti-aging aluminium alloy coaxial-type two core cable.

Two, background technique:

In three-phase power Transmission system, it is desirable that using multi-core power cables such as two cores, three cores, four cores, as the street in city Road lighting system, industry and civil buildings etc. need to use the field of single-phase loop power supply, all be two core aluminium alloy conductor coaxial powers The potential market of cable.Existing multi-core power cable is chiefly used in open air, and cable long-time service is exposed to the sun plus high temperature, tortoise occurs Split, aging the case where, fire can be caused when serious, the smog of generation influences the health and environmental pollution of people.

Three, the content of utility model:

The technical problem to be solved by the utility model is to overcoming the deficiencies of the prior art and provide a kind of anti-aging aluminium conjunction The case where golden coaxial-type two core cable, aging caused by avoiding the sun from being exposed to the sun, cracking, the service life of cable is extended, improved The heat resistance of cable outdoor laying and can be used for indoor location, and the safety effectively avoided in power supply process is hidden Suffer from.

The utility model is adopted the technical scheme that in order to solve the technical problem:

A kind of anti-aging aluminium alloy coaxial-type two core cable successively includes center conductor, insulating layer, same spindle guide from inside to outside Body, shielded layer and oversheath；The center conductor is that rare earth aluminium alloy bar wire drawing process forms using 8000, and the insulating layer is adopted It is formed with crosslinked polyethylene processing of high molecular material, the coaxial conductor is process using 8000 line aluminium alloys, the shielding Layer is formed using aluminium-plastic tape is wrapped, and the oversheath is process using cross-linking polyethylene materials and carbon black materials.

The coaxial conductor is made of several conductor thread cores, and several conductor thread cores are uniformly looped around the insulating layer Outside, the shielded layer is around the outside of several conductor thread cores.

The parts by weight of the carbon black materials are the 2.5% of cross-linking polyethylene materials parts by weight.

The utility model is being guaranteed cable under normal use, is being prolonged using novel structure design and material application The service life for having grown cable improves the heat resistance of cable, outdoor laying and can be used for indoor location, effectively keep away The security risk in power supply process is exempted from.

For the utility model compared with common cable, key technology innovation is embodied in the following:

1. center conductor: it is rare earth aluminium alloy using 8000, is formed by wire drawing, annealing, twisted, annealing operation process, Have many advantages, such as high conductivity, controlled tensile strength, flexibility, elongation, makes cable within the long period overloaded and overheated Has stability.

2. insulating layer: it is formed using one-step method crosslinked polyethylene processing of high molecular material, improves the heat resistance of cable, To the harm very little of environment when burning, meet the requirement of modern fire low smoke and non-toxic, is the insulating materials of environment-friendly cable first choice.

3. coaxial conductor: using 8000 line aluminium alloys, there is good flexibility and bendability, the minimum bend half of cable Diameter (7D) is better than copper core (10~20D) cable, facilitates installation and construction, and can be reduced installation cost.

4. shielded layer: being formed using one layer of aluminium-plastic tape is wrapped, coaxial conductor can be tightened, be allowed to not loosely convenient for crowded Outer jacket out, and can make the field distribution of coaxial conductor uniformly and the interference of external electromagnetic field can be shielded, guarantee transmission of electricity stability.

5. oversheath: using one-step method make somebody a mere figurehead crosslinked polyethylene plastic add 2.5% or more carbon black materials processing and At, have the characteristics that shield sun solar radiation, it is therefore prevented that the crack phenomenon occurred when common cable normal use improves electricity The service life of cable, cable can outdoor laying and indoor location use, improve the utilization rate of cable.

Four, Detailed description of the invention:

Fig. 1 is the structural schematic diagram of the utility model.

Five, specific embodiment:

The utility model is made further explanation in the following with reference to the drawings and specific embodiments:

Embodiment: referring to Fig. 1, a kind of anti-aging aluminium alloy coaxial-type two core cable is successively led including center from inside to outside Body 1, insulating layer 2, coaxial conductor 3, shielded layer 4 and oversheath 5；Center conductor 1 is that rare earth aluminium alloy bar wire drawing twists using 8000 It makes, insulating layer 2 is formed using crosslinked polyethylene processing of high molecular material, and coaxial conductor 3 is processed using 8000 line aluminium alloys Form, shielded layer 4 is formed using aluminium-plastic tape is wrapped, oversheath 5 using cross-linking polyethylene materials and carbon black materials processing and At.

Wherein: coaxial conductor 3 is made of several conductor thread cores, and several conductor thread cores are uniformly looped around the insulating layer 2 outside, shielded layer 4 is around the outside of several conductor thread cores；The parts by weight of carbon black materials are cross-linking polyethylene materials weight The 2.5% of part.

The utility model is guaranteeing cable under normal use, extends the service life of cable, improves cable Heat resistance, outdoor laying and indoor location can be used for, effectively avoid the security risk in power supply process, have Good social utility's value, it is easy to spread.
