Problems solved by technology

In wire and cable, the maximum allowable working temperature of the wire core is 70°C, and it is often made of soft materials such as polyvinyl chloride plastic. However, the strength and wear resistance of these materials are generally low, and the added reinforcing filler materials are not very good. Ground and main material cross-linking, which further affects the use of wire and cable, has become a bottleneck restricting the development of the wire and cable industry
