Embodiment Construction
[0011] Such as figure 1 As shown, the present invention is realized by adopting the following technical solutions: a kind of UV-resistant, high-temperature-resistant and waterproof reinforced cable, which is composed of main wire core 1 and copper tape wrapping layer 4 wrapped in the outer layer of main wire core 1 in turn, ethylene-propylene insulation layer 6, shielding layer 7, anti-ultraviolet layer 8, and silicone rubber protective sleeve 9. The main wire core 1 is four groups, which are evenly extruded inside the copper tape wrapping layer 4, and the copper tape wrapping layer 4 An insulating board 2 is arranged in the center, and the four sides of the insulating board 2 are respectively tangent to the main wire core 1, and a waterproof layer 5 is provided between the copper tape wrapping layer 4 and the ethylene-propylene insulating layer 6, and the waterproof Layer 5 is composed of a number of waterproof tapes that are closely arranged and circumscribed with each other...

The invention discloses an anti-ultraviolet high-temperature-resistant waterproof reinforcing cable. The cable is composed of main line cores, a copper strip wrapping tape layer, an ethylene-propylene insulating layer, a shielding layer, an anti-ultraviolet layer and a silicon rubber protection sleeve. The main line cores are divided into four groups and are evenly arranged in the copper strip wrapping tape layer in a squeezing mode. An insulating plate is arranged at the center of the copper strip wrapping tape layer, and the four edges of the insulating plate are in tangent relation with the main line cores respectively. A waterproof layer is arranged between the copper strip wrapping tape layer and the ethylene-propylene insulating layer and is formed by tightly arraying a plurality of waterproof straps in a mutually externally tangent mode. The cable is waterproof, resistant to interference, high in broken-line-resisting performance, insulating, resistant to high temperature and mainly used in fields like power generation, metallurgy, computers, chemical industry and petroleum, the line cores are firm, and the ultraviolet shielding rate reaches 98.7%.
Description
technical field [0001] The invention belongs to the field of cables, in particular to an ultraviolet-proof, high-temperature-resistant and waterproof reinforced cable. Background technique [0002] In the fields of power generation, metallurgy, chemical petroleum, etc., for cables used in environments such as long-term sunlight or rain erosion, and strong external extrusion, traditional cables using PVC and other materials can no longer meet the actual use of cables. This puts forward higher requirements on the anti-ultraviolet performance of the cable, the firmness of the core, high temperature, electrical conductivity and anti-interference. Only by meeting the requirements can the production and use of cables be better guaranteed. Contents of the invention [0003] In order to overcome the defects of the above-mentioned prior art, the object of the present invention is to provide a UV-resistant, high-temperature-resistant, and waterproof reinforced cable with the advant...
