Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cables, and in particular relates to a multi-layer shielded high-voltage coaxial cable. Background Art
[0002] High-voltage coaxial cables play a vital role in high-voltage power transmission. High-voltage power transmission often involves long distances, and power cables traverse various environments and locations during installation. Some of these locations can interfere with the power cables. Multi-layer shielded high-voltage coaxial cables, with their strong anti-interference properties, play a crucial role in high-voltage power transmission. However, existing multi-layer shielded high-voltage coaxial cables generate heat during use, causing the cable core to expand. This expansion can damage the cable core protective layer, affecting subsequent use. Utility Model Content
[0003] The purpose of this invention is to provide a multi-layer shielded high-voltage coaxial cable to solve the above-mentioned technical problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A multi-layer shielded high-voltage coaxial cable includes a cable core, a cable core protective layer, a first filling layer, a shielding layer, a second filling layer, arc-shaped reinforcing blocks, a first insulation layer, and a second insulation layer. The outer surface of the cable core is wrapped with the cable core protective layer. A first filling layer is provided outside the cable core protective layer. A shielding layer is wrapped outside the first filling layer. The shielding layer has at least two layers, which together form a shielding layer. A second filling layer is wrapped outside the shielding layer. At least two arc-shaped reinforcing blocks are provided in close contact with the second filling layer. The two arc-shaped reinforcing blocks are connected by steel wire ropes. A first insulation layer is provided outside the arc-shaped reinforcing blocks, and a second insulation layer is provided outside the first insulation layer.
[0006] Preferably, a spiral strip is wound around the surface of the first insulating layer. The spiral strip is made of the same material as the first insulating layer and is made of red material. A fluorescent strip is coated on the second insulating layer.
[0007] Preferably, the cable core is provided with multiple arc-shaped grooves, which are arranged at equal intervals along the length of the cable core.
[0008] Compared with the prior art, the present invention has the following advantages: the present invention is reasonably designed; the arc groove on the cable core can expand towards the arc groove after being heated, thereby protecting the cable core protective layer; the arc reinforcing block can deform when squeezed, thereby protecting the cable core; the spiral strip on the first insulation layer can promptly alert people after the second insulation layer is damaged; the fluorescent strip on the second insulation layer can promptly detect cable damage in a dark environment.
