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.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a high life environmental protection cable, including inoxidizing coating 1, second filler 7 and rubber tube 13, the inside parcel of inoxidizing coating 1 has copper-plated copper wire 2, the inside parcel of copper-plated copper wire 2 has fire-retardant oxygen layer 3 that separates, it has high temperature resistant polyester layer 4 to fire-retardant 3 inside parcels that separate the oxygen layer, the inside parcel of high temperature resistant polyester layer 4 has oxygen layer 5 that separates, it has first filler 6 to separate the inside parcel of oxygen layer 5, the outside parcel of rubber tube 13 has one deck memory wire 12, insulating layer 8 is hugged closely to 12 outside one sides of memory wire, 8 inside parcels of insulating layer have high density polyethylene cover 9, the inside parcel of high density polyethylene cover 9 has polypropylene cover 10, the inside parcel of polypropylene cover 10 has conductor 11, second filler 7 is filled in the inside space department of cable.
