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.
