Coaxial bunched cable for 3G (third generation) communication

Abstract

The invention relates to a coaxial bunched cable for 3G (third generation) communication. The coaxial bunched cable comprises a physical foaming polyethylene insulating layer, an aluminum composite tape outer conductor, a tinned copper braid shielding layer and a photothermal-resistant polyethylene protective sheath which are arranged on the exterior of an inner wire of a copper-clad aluminium wire in sequence and also comprises a chemical foaming polyethylene padding core, a non-woven fabric inner protective layer, a cotton yarn tearing rope and a photothermal-resistant polyethylene outer protective sheath, wherein chemical foaming polyethylene padding cores are respectively arranged among four coaxial cables and are twisted together, the exterior of the cables are provided with the non-woven fabric inner protective layer and the photothermal-resistant polyethylene outer protective sheath, and the cotton yarn tearing rope is arranged between the non-woven fabric inner protective layer and the photothermal-resistant polyethylene outer protective sheath. The coaxial bunched cable provided by the invention has the characteristics of stable electric performance index, compact structure and simplicity and convenience in installation and construction, thus the electric performance index of the cable can be ensured not to change along with the change of installation places.

Description

technical field [0001] The patent of the invention relates to a coaxial bundled cable for 3G communication, which is widely used in 3G mobile communication, microwave measurement, aerospace, navigation and other systems. Background technique [0002] At present, there are many 5D-FB physically foamed insulated coaxial cables used in mobile communication and broadcasting construction in my country. When transmitting signals, often a single coaxial cable cannot meet the requirements of use, and coaxial cables with four cores and below are required. , It needs to be laid many times, the construction and installation are very inconvenient, the structure is not compact enough, and it takes up a lot of space. Contents of the invention [0003] In view of the deficiencies in the prior art, the invention provides a coaxial bundled cable for 3G communication. [0004] The present invention is to achieve the above objects. The technical solution adopted is: a coaxial bundled cable ...
