Problems solved by technology

Both of these methods have the problems of slow cable manufacturing and low efficiency. Therefore, there is an urgent need for alternative methods to make shielding layers in the industry.
[0006] Semiconductor shielding materials, because they can be realized by extrusion, and the shielding effect can meet the design requirements, therefore, more and more attention has been paid by the industry. Although various researches and explorations have been carried out on semiconductor shielding materials at home and abroad, but , the applicant feels that the existing semiconductor shielding materials that can be used for cables are not very ideal, for this reason, the applicant has improved

Abstract

The invention belongs to the technical field of cables, and particularly relates to a photoelectric composite cable for a high-voltage network.The photoelectric composite cable comprises a cable core, a semiconductor outer shielding layer (4) wrapping the cable core and a sheath layer (5) wrapping the semiconductor outer shielding layer in an extrusion molding mode.The cable core is composed of three insulating wires and three loose tubes (8) containing light-guide fibers (7) inside, and gaps of the cable core are filled with an insulating material (6).Each insulating wire comprises a conductor (1), a semiconductor inner shielding layer (2) wrapping the conductor and an insulating layer (3) wrapping the semiconductor inner shielding layer in an extrusion molding mode.The loose tubes are distributed between the adjacent insulating wires.The semiconductor inner shielding layer and the semiconductor outer shielding layer are made of special materials.The cable has the main advantages of being more excellent in mechanical performance, current carrying performance, shielding performance and the like, lighter, more stable in after shrinkage, higher in manufacturing speed and lower in cost.

Description

[0001] This application is a divisional application for an invention patent named: a high-voltage transmission cable, application date: July 09, 2014, application number: 201410323526.3. Technical field [0002] The invention belongs to the technical field of cables, and particularly relates to a cable for high-voltage transmission. Background technique [0003] Wire and cable, as a basic industry in the national economy, occupies an increasingly important position in the national economy. It accounts for about 5‰ of the total GDP of the country. Cable products mainly play the role of transmitting energy and information. Therefore, it has always been There is a saying that the cable industry is the "vascular" and "nervous" of the national economy. Because the technical content of wire and cable is not very high, and the required capital investment does not need to be very large, the development is very rapid. [0004] In the field of high-voltage transmission, China’s technology is...
