Polyethylene composite corrosion-resistant high-strength core cable

Abstract

A polyethylene composite corrosion-resistant high-strength core cable is provided with a cable core and a protecting layer. The protecting layer is arranged outside the cable core. A protecting film is arranged outside the protecting layer. The protecting film is provided with an identification part. A code and a cable type are printed on the identification part in an inkjet manner. The inside of the protecting layer is provided with a protecting housing. The protecting housing is made of an alloy. A corrosion-resistant layer is arranged below the protecting housing. The corrosion-resistant layer is internally provided with a nanometer screen. The inside of the nanometer screen is provided with a fixed layer which warps the cable core. The cable is internally provided with an interlayer. The polyethylene composite corrosion-resistant high-strength core cable has advantages of preventing mutual interference in transmission between cable cores, preventing outlet data error in cable transmission, ensuring high data transmission effect of the cable, and furthermore improving corrosion resistance of the cable through arranging the corrosion-resistant layer in the cable.

Description

technical field [0001] The invention relates to a cable, in particular to a polyethylene composite anti-corrosion strong core cable. Background technique [0002] At present, the service life of cables is relatively short, and the frequency of replacement is relatively high, which increases the cost of urban infrastructure construction and cannot be well controlled. Many cables are operated outdoors. Such an operating environment increases the probability of cables being corroded. , the outer surface of many cables is easy to peel off, causing corrosion of the inner core of the cable, interrupting the transmission of the signal, affecting the use effect of the cable, unable to guarantee the normal signal transmission of the cable, affecting the performance of the cable used, reducing the The service life, the strength of the cable is reduced, the cable is easy to break, it cannot be transmitted well, the corrosion resistance of the cable is not strong, and the service life i...
