Description

Technical Field

[0001] The utility model relates to the technical field of power cables, in particular to an environmentally friendly modified polypropylene insulated power cable. Background Art

[0002] Power cable is a cable used to transmit and distribute electrical energy. It consists of a conductor, an insulation layer, a sheath and other accessories. Power cable is widely used in power systems, construction projects, industrial equipment and other fields to transmit AC or DC power.

[0003] After searching, it was found that the publication number is CN219759266U, and the name is an environmentally friendly modified polypropylene insulated power cable. The device uses a filling layer to fill and fix the cable wires inside the cable. Although it can fix the cable wires well, after the cable service life is over, it needs to be recycled and disassembled for safety reasons. Since the filling layer makes the inside of the cable fuller, it is more difficult to recycle and cut. The position of the internal cable wires cannot be seen intuitively, and it is easy to cut the cable wires by mistake, resulting in the cable wires being cut off, affecting the selling price. A relatively simple disassembly process is required to achieve a better disassembly effect, so further improvements can be made.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0026] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] According to an embodiment of the utility model, an environmentally friendly modified polypropylene insulated power cable is provided.

[0028] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-3 As shown, according to an embodiment of the utility model, an environmentally friendly modified polypropylene insulated power cable includes a positioning skeleton 1 and a waterproof layer 13. The positioning skeleton 1 is arranged inside the waterproof layer 13. A wire placement groove 7 is opened on the positioning skeleton 1. Vertical rubber strips 8 and horizontal rubber strips 9 are fixedly installed in the wire placement groove 7 respectively. A modified polypropylene insulation layer 6 is clamped in the wire placement groove 7. The interior of the modified polypropylene insulation layer 6 is wrapped with a semi-conductive polypropylene conductor shielding layer 5. The interior of the semi-conductive polypropylene conductor shielding layer 5 is wrapped with a cable 4. A positioning line 14 is fixedly installed on the surface of the waterproof layer 13.

[0029] In one embodiment, a decompression center hole 2 and a decompression side hole 3 are respectively opened in the positioning frame 1, and the decompression center hole 2 and the decompression side hole 3 save materials.

[0030] In one embodiment, the waterproof layer 13 is wrapped with the outer protective layer 12 .

[0031] In one embodiment, the outer sheath 12 is enclosed by an armor layer 11 .

[0033] In one embodiment, the inner protective layer 10 is wrapped with the positioning frame 1 , and the inner protective layer 10 can protect the cable 4 and the positioning frame 1 .

[0034] In one embodiment, a reflective sticker 15 is affixed to the surface of the waterproof layer 13. When construction is carried out at night, the reflective effect of the reflective sticker 15 can facilitate observation of the cables, thereby preventing workers and passers-by from tripping over the cables due to not being able to see them clearly.

[0035] Working principle: a positioning skeleton 1 and positioning lines 14 are adopted, and the cable line 4, the semi-conductive polypropylene conductor shielding layer 5, and the modified polypropylene insulating layer 6 are clamped and fixed through the line placement groove 7 opened on the positioning skeleton 1.
