Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

As shown in fig. 1-3, an environment-friendly flame-retardant composite cable comprises a wrapping layer 1, wherein a mounting structure is arranged in the wrapping layer 1, and a protective structure is arranged on the outer side of the wrapping layer 1;

it should be noted that, the multi-strand cable is installed in the wrapping layer 1 through the installation structure, and the flame retardant, waterproof and overall strength effects of the cable are improved through the protection structure outside the wrapping layer 1.

In a specific implementation, the mounting structure comprises: the device comprises five insulating mounting tubes 2, a mounting frame 3, four fixing rods 4 and four supporting rods 5;

four insulating installation pipe 2 all place in parcel layer 1, and installation frame 3 is installed in parcel layer 1, and with four insulating installation pipe 2 among them, four dead lever 4 one ends all are connected with installation frame 3, and the other end all is connected with another insulating installation pipe 2, and four 5 one ends of bracing piece all are connected with four insulating installation pipe 2 among them, and the other end all is connected with parcel layer 1 internal face.
