[0006] Preferably, the rough soft capillaries on the outer surface of the flame retardant heat insulating wrapped mica are fused inside the halogen-free coating plastic, so that the halogen-free coating plastic and the flame retardant heat insulating wrapped mica are tightly combined.

[0007] Preferably, the limit support rods are offset from each other by sixty degrees and are equidistantly inserted into the rock wool braided rope.

[0017] It should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only structures and / or processing steps closely related to the scheme according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0018] See Figure 1-Figure 3As shown, this specific embodiment adopts the following technical scheme: it includes a rock wool braided rope 1, a limiting support rod 2, a copper core of an electric wire 3, a flame retardant and heat-insulating wrapped mica 4, rough capillary soft needles 5, and a halogen-free coated plastic 6; a circle of copper core of an electric wire 3 is arranged on the outer side of the rock wool braided rope 1, and the copper core of the electric wire 3 is fixed in position by a limiting support rod 2 inserted into the inside of the rock wool braided rope 1; the outer side of the copper core of the electric wire 3 is evenly wrapped with flame retardant and heat-insulating wrapped mica 4, and a plurality of rough capillary soft needles 5 are bonded to the outer surface of the flame retardant and heat-insulating wrapped mica 4, and a halogen-free coated plastic 6 is arranged on the outer surface of the flame retardant and heat-insulating wrapped mica 4.

[0019] Among them, the rough capillary soft needles 5 on the outer surface of the flame retardant and heat-insulating wrapped mica 4 are fused inside the halogen-free coated plastic 6, so that the halogen-free coated plastic 6 is tightly combined with the flame retardant and heat-insulating wrapped mica 4; the limiting support rods 2 are staggered sixty degrees from each other and are equidistantly inserted into the interior of the rock wool braided rope 1.
