Anti-friction cluster signal cable for 4G communication base station

Abstract

The invention discloses an anti-friction cluster signal cable for a 4G communication base station. The cable core comprises an inner conductor layer, an insulating layer, a braided shield layer, an immersion tin layer, and an inner sheath layer; the insulating layer is coated outside the inner conductor layer, and the insulating layer is extruded and wrapped on the surface of the inner conductor layer by using a polytetrafluoroethylene material; the braided shield layer is coated outside the insulating layer, the braided shield layer is immersed in tin liquid, and the immersion tin layer is formed on the surface of the braided shield layer; the outer surface of the immersion tin layer is extruded and wrapped with the inner sheath layer; the outer surface of the signal cable cluster composed of a plurality of cable cores is wound with a common wrapping layer of an FEP material; and an outer sheath layer of the FEP material is arranged on the outer surface of the wrapping layer. The physical and mechanical property strength is high, the flame retardancy is good, the high and low temperature resistance is good, and the signal transmission attenuation is small with temperature.

Description

Technical field [0001] The invention relates to a communication signal cable, in particular to a bundled signal cable used in a friction-proof 4G communication base station. Background technique [0002] With the comprehensive acceleration of 4G communication technology, the construction scope and number of 4G base stations are also expanding and expanding. While the demand for radio frequency coaxial cables for connecting and transmitting signals is increasing, the cable transmission performance and safety performance are increasing. The problem of the problem has also increased; for example, the clustered coaxial cable connecting the communication equipment and the antenna in the base station room needs to ensure good signal transmission performance, but also need to ensure reliable resistance to environmental weather and fire resistance. However, the traditional signal cable uses physical foamed polyethylene as the transmission medium carrier, and the core is completed by the ...
