4 is an exemplary cross-sectional view showing a power cable structure according to a second embodiment of the present invention.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

[First Embodiment]

Tape according to the first embodiment of the present invention is composed of "PVC or PE adhesive layer / nylon film layer / adhesive layer / aluminum layer / adhesive layer / nylon film layer / PVC or PE adhesive layer", and work in the cable manufacturing (Longitudinal taping) The tape overlapping part is adhered to, and it is extruded with PVC or PE on the outside to form a sheath layer, thereby reinforcing the insect repellent function from insects such as termites, and significantly reducing the weight per length as well as moisture. It also prevents moisture from penetrating, making it possible to extend the life of cables.

Such a tape according to the present invention completely replaces the conventional soft pea layer that constitutes the power cable.

The power cable according to the present invention protects the insulator so that the insulator coating is not easily broken or destroyed, and at the same time, the present invention tape instead of the conventional softwood layer to enhance the insect repellent function to protect from insects such as termites and to increase the insulation effect. It includes a tape layer replaced with, the structure is as follows as described above.

That is, the power cable according to the present invention, as shown in Figure 2, the conductor 10-insulator (conductor insulation 20)-filler 30-PP or non-woven tape 40-bedding layer 50- It consists of a tape layer 65 and a sheath layer 70, wherein the tape layer 65 has the same tape structure as the first embodiment shown in FIG.

More specifically, as shown in FIGS. 2 and 3, in the tape layer 65 according to the first embodiment of the present invention, a first adhesive layer 200 is formed on the bedding layer 50, and the first adhesive layer 200 is formed on the tape layer 65. The first nylon film layer 300 is formed on the first adhesive layer 200, the second adhesive layer 400 is formed on the first nylon film layer 300, and the second adhesive layer ( 400, an aluminum layer 500 is formed on the upper portion, a third adhesive layer 600 is formed on the aluminum layer 500, and a second nylon film layer 700 is formed on the third adhesive layer 600. ) Is formed, the fourth adhesive layer 800 is formed on the second nylon film layer 700, and the sheath layer 70 is formed thereon.

In addition, the tape layer 65 has a total thickness of about 0.2mm to 0.4mm, and since the tape is mostly tape-shaped, the weight (load) per length is significantly reduced compared to conventional lead.

For example, considering that the thickness of the conventional soft peas layer is about 2.5mm compared to the thickness of the tape layer 65 of the present invention, the thickness of the conventional soft peas layer is 8 to 9 times thicker than the thickness of the tape layer 65 of the present invention. It can be seen that.

In addition, the second and third adhesive layers 400 and 600 are bonding materials for configuring the tape layer 65, and it is preferable to further enhance the waterproof function by increasing watertightness through chemical treatment.

In particular, the watertight treatment is more preferably concentrated on the overlapped portion (rolled-up portion) M.

In this case, the reason why the waterproof function by the second and third adhesive layers 400 and 600 is necessary is that the first and second nylon film layers 300 and 700 of the tape layer 65 and the aluminum layer 500 are extruded. This is because waterproofing in the interlayer and end overlapping portions by the tape closing operation is essential because it is not a form but a form to be treated by an adhesive.

In addition, the first and fourth adhesive layers 200 and 800 are usually made of PVC or PE so that the adhesive force with the bedding layer 50 or the sheath layer 70 is maximized.

In addition, as described above, the first and second nylon film layers 300 and 700 are supplied in a rolled form in which a film in a tape form is wound, and in particular, nylon 6 or nylon 12 or nylon 66 is preferably used.

In this case, the first and second nylon film layers 300 and 700 are made of nylon 6 or nylon 12 or nylon 66 because they have sufficient strength and have excellent insect repellency against termites.

In addition, the aluminum layer 500 disposed between the first and second nylon film layers 300 and 700 is for enhancing the strength, waterproofing, and heat dissipation effect, and is excellent in bonding properties with nylon.

In addition, the aluminum layer 500 has a foil shape and is preferably wound in a roll shape.

In addition, since the first and second nylon film layers 300 and 700 are in the form of a film (tape), the overlapped overlapped portion may be further bonded by applying heat to the overlapped portion.

Accordingly, in the tape layer 65 of the present invention, the first nylon film layer 300 made of nylon is formed on the first adhesive layer 200, and a second adhesive layer 400 is formed thereon. The aluminum layer 500 is formed while the foil-shaped aluminum is adhered and fixed on the second adhesive layer 400, and the third adhesive layer 600 is applied and formed on the aluminum layer 500, and the third adhesive agent is formed. The second nylon film layer 700 made of a nylon material in the form of a film is formed on the layer 600, and the fourth adhesive layer 800 is formed on the second nylon film layer 700.

Thereafter, the tape layer 65 is formed on the bedding layer 50 as the end to form an overlap M, which is extruded PVC or PE thereon to overlap the terminal surface of the tape layer 65 with the overlap. The sheath layer 70 is formed while completely sealing the portion M in a circular shape, thereby completing the power cable of the present invention.

Tape layer 65 made of such a structure is equal to or more than the existing characteristics, the thickness can be further reduced, and also the weight can be significantly reduced, in particular, excellent insect repellent against termites, durability and long life, waterproof, Excellent heat dissipation effect is very effective when placed in the ground of the region such as the Middle East.

For example, in the case of a three-core × 300 mm2 cable, the lead requirement is 5,690 kg / km in the conventional structure, whereas the tape according to the present invention requires only 118 kg / km. It can be seen that.

In addition, in terms of cost, in the case of a three-core x 300 mm 2 cable, the amount of lead used is 13 times more than that of the present tape.

[Second Embodiment]

2 and 4 according to the present invention, based on the structure described above, that is, a structure having an aluminum layer between the nylon layer and the nylon layer, as shown in Figures 2 and 4, the type and number of adhesive layers are adjusted It is configured to have a different form.

In other words, the power cable according to the second embodiment of the present invention includes a conductor 10-an insulator (conductor insulation) 20-a filler 30-PP or a nonwoven tape 40-a bedding layer 50-a tape layer ( When formed in the same form as the 65) -sheath layer 70, the structure of the tape layer 65 has the form as shown in FIG.

That is, in the tape layer 65 according to the second embodiment of the present invention, the same first nylon film layer 300 as described in the first embodiment is formed on the top of the bedding layer 50.

In addition, a lower adhesive layer 400 ′ is formed on the first nylon film layer 300, an aluminum layer 500 is formed on the lower adhesive layer 400 ′, and the aluminum layer 500. The upper adhesive layer 600 'is formed on the upper part of the upper side), and the same second nylon film layer 700 as described in the first embodiment is formed on the upper adhesive layer 600'. The sheath layer 70 is bonded through the nylon adhesive layer 200 ′.
