Problems solved by technology

However, the existing hybrid cable sheath materials have weak aging resistance, tear resistance, and compression resistance. If the above functions are to be enhanced, multiple protections need to be deployed, resulting in an increase in cable diameter and cable weight. The tearing and compressive properties are good, and there is no need to lay multiple protective hybrid cable sheath materials, which needs to be solved urgently, and the internal structure of the existing photoelectric hybrid cable is not tight enough, and the stability is poor

Abstract

The invention relates to a photoelectric hybrid cable applied to the communication power industry, which comprises a first protective layer and a second protective layer arranged inside the first protective layer, wherein the inner side wall of the second protective layer is provided with a copper net shielding layer, the inner side wall of the copper net shielding layer is provided with a non-woven fabric wrapping tape, the internal part of the wrapping tape is provided with an electric assembly, two control assemblies and two optical fiber assemblies in a penetrating manner, each control assembly comprises an aluminum foil shielding layer and a twisted-pair control line arranged in the aluminum foil shielding layer in a penetrating manner, each optical fiber assembly comprises an opticalfiber and a fluoroplastic tape wound outside the optical fiber, the two control assemblies and the two optical fiber assemblies are distributed in a square mode and respectively abutted against the inner side wall of the wrapping tape, the electric assembly comprises a plurality of cables arranged in the wrapping tape, the wrapping tape is internally filled with aramid fibers, and the second protective layer is a fluoroplastic protective layer. The photoelectric hybrid cable not only is stable in structure and excellent in waterproof and heat resistant effect, but also is compact in internalstructure, flame resistant and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of photoelectric hybrid cables, in particular to photoelectric hybrid cables used in the communication power industry. Background technique [0002] With the rapid development of multimedia technology, people have put forward higher and higher requirements for multimedia transmission quality, especially for high-definition multimedia. The original multimedia that simply transmits video or audio signals cannot meet the needs of today's society. The optical hybrid cable is a cable in which an optical cable and a cable are twisted together. It adds an insulated conductor to the optical cable structure and integrates an optical fiber and a power transmission copper wire. Since optical transmission and electric power transmission belong to two different types of transmission methods, there will be no mutual interference during the transmission process, and at the same time, it can solve the problems of equipment ...
