In modern society, computer networks and the internet have become an integral part of people's lives and works. While ethernet cable is one of the most common transmission mediums in-car networks and the internet, its importance and application breadth are self-evident.
In vehicles, it is often necessary to perform a large number of data transmissions and transmission of control signals, such as communication between devices of an in-vehicle multimedia entertainment system, a driver information display screen, various sensors, controllers, and the like, and a bus network of the vehicle, and the like. Data transmission between these devices requires a stable, high-speed, reliable and tamper-resistant communication link. Meanwhile, the environment inside the vehicle is complex, and factors such as high temperature, high humidity, high pressure, high corrosiveness and the like exist, so that a common Ethernet cable can not bear long-term use in the environment, and is easy to damage, so that the data transmission rate is reduced or fails.
In the prior art, common ethernet cable insulation materials mainly include PP (polypropylene), PE (polyethylene), LSZH (low smoke zero halogen) and the like. The physical properties and chemical properties of the materials have certain advantages and limitations, such as abrasion resistance, tensile strength, high temperature resistance, chemical corrosion resistance, flame retardance and the like.
However, these insulating materials may not perform adequately in severe environments, such as high temperature, high pressure, and high corrosion environments, where problems such as aging, degradation, deformation, and cracking of the insulating layer may occur, thereby affecting the transmission rate and transmission quality of the ethernet cable.
In addition, the insulating layers of the ethernet cable in the prior art are mostly in a single-layer structure, so that the anti-interference performance of the ethernet cable may be poor, and the ethernet cable is susceptible to external electromagnetic interference to generate transmission error codes. In addition, there have been some attempts in the prior art to improve the performance of ethernet cables in harsh environments using other materials and techniques. For example, there have been attempts to manufacture an insulation layer of an ethernet cable using a material such as fluoroplastic to improve its high temperature resistance, abrasion resistance, corrosion resistance, and the like. There have also been some attempts to co-extrude insulating layers of different materials together using a multi-layer co-extrusion technique to achieve multiple protection and protection objectives. However, due to poor adhesion between different materials, the problems of stripping or cracking of an insulating layer and the like may be caused after long-term use, thereby affecting the reliability and service life of the Ethernet cable.
