[0002] Power cables mainly include conductors, insulation layers wrapped around the conductors, and flame-retardant tapes placed outside the insulation layers. Flame-retardant tapes are generally made by mixing a single flame retardant with cable materials. Large amounts of flame retardants will produce a lot of smoke and toxic gases when burned, and are easily washed away by rainwater. They are easy to change after being damp, have poor stability, and their effective fire-retardant performance is seriously affected.

[0003] When the existing flame retardant tape is used to protect the outside of the cable, since part of the cable is on the ground, when the flame retardant tape is wrapped, friction between the cable and the ground is likely to occur, which may easily cause the flame retardant tape to be damaged and reduce the flame retardant effect.
