The method is beneficial to increase the interference resistance of bundle signal cables, has the advantages such as small transmission attenuation value, superior high and low-temperature resistance performance, high transmission rate, stable and reliable transmission performance and easy installation in high and low temperature environments, and has good physical strength and environmental climate resistance, as well as extensive corrosion resistance and non-combustibility.

Description

technical field [0001] The invention relates to a communication signal cable, in particular to a method for pushing an insulation layer of a cable core. 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 completed by high-temperature melting ...
