In order to achieve the above purpose, the present utility model adopts the following technical scheme: a fire-resistant cable, comprising: the copper core strip, the surface cover of copper core strip is fit and is connected with the insulating cover, be equipped with the mica filling strip around the insulating cover, the surface cover of insulating cover and mica filling strip is equipped with the fire prevention adhesive tape.

As a preferred embodiment, the fireproof adhesive tape is in glued connection with the insulating sleeve and the mica filling strip, and the outer surface of the fireproof adhesive tape is sleeved with the PVC adhesive sleeve.

As a preferable implementation mode, the outer surface of the PVC rubber sleeve is sleeved and connected with a thin aluminum pipe.

As a preferred embodiment, the outer surface of the thin aluminum tube is sleeved with a fireproof mud heat insulation layer.

As a preferred embodiment, the fire clay insulating layer is bonded to the thin aluminum tube.

As a preferable implementation mode, the fireproof rubber is sleeved on the outer surface of the fireproof mud heat insulation layer.

Compared with the prior art, the utility model has the advantages and positive effects that:

according to the utility model, the insulation sleeve is sleeved on the outer surface of the copper core strip, so that the current of the copper core strip cannot be transmitted to the outside, the insulation sleeve can protect the copper core strip, the reduction of the service life of the copper core strip caused by direct contact of external substances and the copper core strip is prevented, the failure rate of the copper core strip can be reduced, the fireproof adhesive tape is arranged, the connection of the copper core strip, the insulation sleeve and the mica filling strip is more compact, the cylindrical shape of the copper core strip, the insulation sleeve and the mica filling strip can be better kept, and the fireproof rubber is arranged on the basis of good but performance, has good flame retardant and high temperature resistance, has corrosion resistance, and has a stable and continuous survival state whether deeply buried or exposed outside.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

As shown in fig. 1 and 3, the present utility model provides a technical solution: the outer surface of fireproof adhesive tape 4 is sleeved and connected with PVC gum cover 5, the outer surface of PVC gum cover 5 is sleeved and connected with thin aluminum pipe 6, the outer surface of thin aluminum pipe 6 is sleeved and connected with fireproof mud insulating layer 7, fireproof mud insulating layer 7 is connected with thin aluminum pipe 6 veneer, and the outer surface of fireproof mud insulating layer 7 is sleeved and connected with fireproof rubber 8.

In this embodiment, through setting up fire prevention rubber 8 for this type fireproof cable has good form wherever to use, and based on its corrosion-resistant and high temperature resistant characteristic, install fire prevention rubber 8 additional in the outside, alright keep this type cable stability of use, in addition, fire prevention rubber 8 and fire prevention mud insulating layer 7's cooperation is used, can be better separate external fire, and fire prevention mud insulating layer 7's thermal-insulated performance, can guarantee the security of inside copper core strip 1 transmission in certain time, and set up PVC gum cover 5 and thin aluminum pipe 6, further strengthen in corrosion-resistant, the easy plasticity's characteristic, and thin aluminum pipe 6 can not lead to the difficulty of fire prevention cable laying because of the hardness of cable is too big again on the basis of guaranteeing plasticity.
