A high-pressure, noise-resistant, flame-retardant, and high-temperature-resistant cable

Abstract

A high-pressure-resistant, noise-resistant, flame-retardant, and high-temperature-resistant cable, a cable sleeve and a cable core, and a heat-insulating buffer layer is arranged between the cable sleeve and the cable core; the heat-insulating buffer layer is provided with a number of through holes for the cable core to pass through. The heat-insulating buffer layer is composed of heat-insulating buffer materials, including 20-30 parts of silicone resin, 5-13 parts of sodium fluorosilicate, 3-10 parts of nano-silicon carbide powder, and 3-10 parts of nano-aluminum nitride , 1-8 parts of vulcanized polyisoprene, 1-10 parts of acid solvent, 1-3 parts of structural vulcanizing agent; the insulation buffer layer is filled between the cable sleeve and the cable core to play the role of filling buffer, and at the same time When the heat generated by the cable can be transferred to the thermal insulation buffer layer layer by layer, because the thermal insulation buffer layer and the cable core are wrapped, the heat of the cable can be transferred to the thermal insulation buffer layer with great efficiency, thereby reducing the cable core. In addition, because the thermal insulation buffer layer has a certain thickness, it can also isolate the external heat to a certain extent.

Description

technical field [0001] The invention relates to a 5G communication cable, in particular to a high-pressure, noise-resistant, flame-retardant, and high-temperature-resistant cable. Background technique [0002] 5G technology will make ultra-high-speed transmission the norm, and a large number of mobile terminals will receive better data support, and the world will become more connected and smarter. In 5G core facilities, communication cables are the most basic and indispensable part. Once a problem occurs, it will affect the entire network. [0003] 5G technology provides significant new capacity and data transmission speed. As an important carrier for transmitting information, communication cables need to be deployed at a higher density to support multi-port communication. It is precisely because of its high-density deployment characteristics that communication cables are prone to heat and heat dissipation problems when transmitting radio frequency signals.

Problems solved by technology

It is precisely because of its high-density deployment characteristics that communication cables are prone to heat and heat dissipation problems when transmitting radio frequency signals. This problem will directly affect the transmission parameters such as cable attenuation and delay, thus becoming a limit for transmission in 5G scenarios. The speed is an important factor, and it prevents users from getting high-speed Internet experience; in addition, cables used in industries such as energy, petrochemical, metallurgy, and electric power have many lines that work at high temperatures for a long time, so the resistance to cables High temperature performance requirements

[0004] For example, the Chinese patent application number "2011110381652.0" discloses a communication cable with high temperature resistance and high flame retardancy. Excellent flame retardancy, low smoke generation and low flame retardancy, can be used continuously in the temperature range below 200°C, and its performance does not change under the limit of 260°C; but the simple structure in the above patent It has good high temperature resistance, but still needs to be improved in terms of heat dissipation for communication cable cores
