Description

technical field

[0001] The invention relates to the related field of communication cables. More specifically, the present invention relates to a signal cable. Background technique

[0002] With the development and popularization of electronic technology products, signal cable, as a tool for transmitting signals, is a common and indispensable tool in industrial production and daily life. However, some signal cables need to be exposed to the air for a long time and are easily affected by moisture. Therefore, the signal cables need to be waterproof and moisture-proof. And if a fire occurs, the flammable signal cable will soon become a medium for spreading the fire, so the signal cable also needs to have flame-retardant and fire-resistant functions. During the laying or transmission process, the signal cable is particularly vulnerable to being squeezed and pulled. Once the core wire is broken or broken, it will cause heavy losses. Therefore, the signal cable also needs to have...
