Fully dry photoelectric composite cable

Abstract

The invention discloses a fully dry photoelectric composite cable, which comprises a cable core, a sheath assembly wrapping the cable core and a water blocking layer arranged between the cable core and the sheath assembly, the cable core includes an optical cable unit, The data communication cable unit and the power line unit are provided with a metal strengthening member in the cable core, and the optical cable unit, the data communication cable unit and the power line unit are surrounded by the metal strengthening member. In the present invention, several cable units for transmitting signals are placed together, which can simultaneously transmit optical signals and electrical signals, and can effectively save pipeline space and reduce production and installation costs; Expandable water-blocking yarn and water-blocking tape replace traditional ointment, which is not only clean and environmentally friendly, but also convenient for construction.

Description

technical field [0001] The invention relates to cables, in particular to an all-dry photoelectric composite cable. Background technique [0002] With the rapid development of my country's information industry, especially the use and mass promotion of 3G communication, the application and technological innovation of optical fiber and cable have been paid more and more attention by the industry. At present, in the communication construction of cities and enterprises, since optical cables and communication cables are products of two different transmission methods, the two products can only be laid separately, and the design cost, purchase cost, installation connection and maintenance are relatively high; in addition, In order to prevent water from seeping into the cable, traditional optical cables and cables are generally filled with ointment or mixed with dry water-blocking materials. Due to the shortcomings of the ointment, which is not easy to clean and has poor low-temperat...

Problems solved by technology

At present, in the communication construction of cities and enterprises, since optical cables and communication cables are products of two different transmission methods, the two products can only be laid separately, and the design cost, purchase cost, installation connection and maintenance are relatively high; in addition, In order to prevent water from seeping into the cable, traditional optical cables and cables generally use ointment filling or ointment mixed with dry water-blocking materials. Due to the shortcomings of ointment that is not easy to clean and poor low temperature performance, the construction is more complicated
