Photoelectric hybrid cable

Abstract

The invention discloses a photoelectric hybrid cable, which comprises at least three optical fiber cables, at least six power cables and a temperature measuring optical cable, wherein the optical fiber cables abut on one another two by two; each optical fiber cable comprises a plastic armor pipe with a plurality of pore channels; optical fibers are arranged in the pore channels of each plastic armor pipe; a first wrapping layer surrounds the outside of the optical fiber cables and is tightly connected with the optical fiber cables; the power cables adjacently surround the outside of the first wrapping layer; each power cable comprises a plurality of conductors; each conductor is surrounded by an insulating layer; a second wrapping layer surrounds the outside of the power cables and is tightly connected with the power cables; and the temperature measuring optical cable is arranged at the center of a hollow cavity enclosed by the optical fiber cables. According to the photoelectric hybrid cable, high-speed and safe transmission of power and information can be simultaneously achieved; the photoelectric hybrid cable is easy to lay; the material and labor cost is low; and the service lifetime is long.

Description

technical field [0001] The technical field of optical cables of the present invention, in particular, relates to a photoelectric hybrid cable capable of simultaneously transmitting optical signals and electrical signals. Background technique [0002] Optical hybrid cable is a new type of access method, which integrates optical fiber and transmission line, and can solve problems such as broadband access, equipment power consumption, and signal transmission. [0003] With the rapid development of the national economy and society and the continuous improvement of people's living standards, the whole society has higher and higher requirements for safety, economy, and high-quality electricity consumption, and the pressure on the safe operation and management of power grids is increasing; at the same time, the needs of users The amount of information is increasing exponentially. The user's demand for exponentially increasing information cannot be met by traditional information tra...

Problems solved by technology

However, the outer diameter of existing optical-electrical hybrid cables is generally large

In addition, because the optical fiber itself has the characteristics of thin diameter, soft quality, and light weight, the optical fiber is easily affected by external tension and external impact force applied to the cable, which leads to poor information transmission.
