Bundle signal cable for anti-friction 4G communication base station

Abstract

The invention discloses a bundle signal cable for an anti-friction 4G communication base station. The cable core comprises an inner conductor layer, an insulation layer, a braided shielding layer, animmersion tin layer and an inner sheath layer, wherein the insulating layer is coated out of the inner conductor layer, the insulating layer is extruded on the surface of the inner conductor layer byusing a polytetrafluoroethylene material, a braided shielding layer covers the outside of the insulating layer and is immersed in the tin liquid, the immersion tin layer is formed on the surface of the braided shielding layer, and the outer surface of the immersion tin layer is extruded with the inner sheath layer. The outer surface of the signal cable bundle composed of a plurality of cable coresis wound with a common polyfluoroethylene propylene material wrapping layer, and the outer surface of the wrapping layer is provided with an outer sheath layer made of polyfluorinated ethylene propylene material. The bundle signal cable has the advantages of high physical and mechanical properties and strength, good flame retardancy, good high and low temperature resistance and small signal transmission attenuation with temperature.

Description

technical field [0001] The invention relates to a communication signal cable, in particular to a shielded bundled signal cable used in an anti-friction 4G communication base station. Background technique [0002] With the comprehensive and accelerated development of 4G communication technology, the construction scope and quantity of 4G base stations are also constantly expanding and expanding. While the demand for RF coaxial cables used to connect and transmit signals is increasing, the transmission performance and safety performance of cables The number of problems has also increased; for example, the bundled coaxial cables connected between the communication equipment and the antenna in the base station room need to ensure good signal transmission performance, and also need to ensure reliable environmental resistance and fire resistance. However, traditional signal cables use physically foamed polyethylene as the carrier of the transmission medium, and the core is complete...
