Problems solved by technology

[0002] At present, cables are used as signal connection lines between various electrical appliances, instruments and automatic devices. In important economic fields such as industrial and mining enterprises, transportation, etc., the existing cables are often immersed in oil stains during use, and the tensile strength and crack resistance are significantly reduced, resulting in a short service life of the existing cable cores.
