Electric power composite cable having double-layer rectangular rubber skeletons

Abstract

The invention discloses an electric power composite cable having double-layer rectangular rubber skeletons. The electric power composite cable comprises an outer rectangular rubber skeleton and an inner rectangular rubber skeleton of which the cross section is a rectangular shape, wherein the inner rectangular rubber skeleton is arranged in the outer rectangular rubber skeleton, four concave arc-shaped isolation backing plates are respectively arranged between four inner walls of the outer rectangular rubber skeleton and four outer walls of the inner rectangular rubber skeleton, the inner rectangular rubber skeleton is internally provided with a fiber cable core, and data cable cores are respectively arranged between the four concave arc-shaped isolation backing plates and the four inner walls of the outer rectangular rubber skeleton. The electric power composite cable is advantaged in that the outer rectangular rubber skeleton and the inner rectangular rubber skeleton are matched foruse, the arc-shaped isolation backing plates are added between the two, the structure is novel, design is reasonable, the internal portion of the cable is more compact, strong stability is realized, signal transmission is not mutually influenced, the cable volume is small, weight is light, and service life is long.

Description

technical field

[0001] The invention relates to the technical field of cables, in particular to an electric composite cable with a double-layer rectangular rubber skeleton. Background technique

[0002] With the continuous expansion of China's electric power industry, data communication industry, urban rail transit industry, automobile industry and shipbuilding and other industries, the demand for wire and cable will also grow rapidly, and the wire and cable industry still has huge development potential in the future.

[0003] The consumption of composite cables in all walks of life is also increasing sharply. However, according to different transmission effects, the existing optical cables and cables are screened in the market. After screening, the required optical cables and cables cannot be effectively integrated. The various functional cores of the cable affect each other, which affects the transmission efficiency and function. Contents of the invention
