Environmentally-friendly rodent-proof low-loss RF integrated coaxial cable for ship

Abstract

The invention relates to an environmentally-friendly rodent-proof low-loss RF integrated coaxial cable for ships. The environmentally-friendly rodent-proof low-loss RF integrated coaxial cable comprises strand wire cores, a stable framework, filling materials and an outer protection layer, wherein each strand wire core comprises a metal wire core, an insulating layer, a shielding layer and a strand wire sheath layer, the stable framework for stabilizing the cable structure is arranged at a strand wire cabling center, and the special-shaped filling materials for stabilizing the cable structure are arranged among the strand wire cores and the outer protection layer; one insulating layer, one shielding layer and one strand wire sheath layer are sequentially arranged outside each metal wire core; and each outer protection layer sequentially comprises an inner protection layer, an armor layer and a rodent-proof outer protection layer from inside to outside, the inner protection layer is made of a hydrophobic material, and the armor layer is made of a rust-preventing non-magnetic metal material and is in a belt-wound form or a braided form. The environmentally-friendly rodent-proof low-loss RF integrated coaxial cable for ships has the innovative effects of electromagnetic interference resistance, low attenuation performance and certain anti-mechanical damage performance, can prevent the cable from being bitten and damaged by mice, facilitates the distributive installation and use of a plurality of sets of equipment, and improves the fidelity performance of video transmission of the RF integrated coaxial cable for ships.

Description

[0001] Technical field: [0002] The invention relates to a coaxial cable, in particular to an environment-friendly anti-mouse-biting low-loss radio frequency integrated coaxial cable for ships. [0003] Background technique: [0004] At present, most of the domestic RF coaxial cables are composed of inner conductor, outer conductor, insulation and sheath, and they are all installed and used in a single cable, without multiple integrated structure design, resulting in chaotic cable wiring and cumbersome maintenance and repair. This kind of cable does not have the performance of preventing mice from biting, and the structural stability, anti-electromagnetic interference, and low loss of the cable are poor. Due to the damage of being bitten by rats, the video signal is interrupted, causing great harm to society, personal property, especially military and national defense facilities. The use of bundled laying causes increased loss, unstable or distorted video transmission signals...

[0004] At present, most of the domestic RF coaxial cables are composed of inner conductor, outer conductor, insulation and sheath, and they are all installed and used in a single cable, without multiple integrated structure design, resulting in chaotic cable wiring and cumbersome maintenance and repair.

This kind of cable does not have the performance of preventing mice from biting, and the structural stability, anti-electromagnetic interference and low loss of the cable are poor

Due to the damage caused by rat bites, the video signal is interrupted, causing great harm to society, personal property, especially military and national defense facilities.

The use of bundled laying causes increased loss, unstable or distorted video transmission signals

In order to overcome the problem of mice biting, at home and abroad, the anti-rat-biting sheath layer containing highly toxic chemicals is mainly used to cover the cable. When the mouse bites and damages the cable, it will be poisoned and killed. The role of real cable protection
