[0002] Jing Technology

[0003] A cable is a device for transmitting electrical energy or signals. It is usually composed of several or several groups of wires. Each group of wires is insulated from each other and often twisted around a central wire. The entire outer layer is covered with a highly insulating covering. Cables include power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, and aluminum alloy cables.

[0004] Most existing cables have poor flame retardant properties. When the cable core is short-circuited or due to other high temperature reasons, the cable catches fire from the inside and cannot effectively prevent the spread of fire.
