Problems solved by technology

[0002] Computer cables are cables suitable for connecting electronic computers with high requirements for anti-electromagnetic interference with rated voltages of 300 / 500V and below, automatic control, instrument detection, etc. Lines require a large number of fire-resistant and flame-retardant computer cables, but the fire-resistant and mechanical properties of existing computer cables cannot meet the growing needs, which poses a great hidden danger to the safety of line equipment and personnel
