Drawings
Fig. 1 is a schematic structural view of an environment-friendly cable.
In the figure: 1. a copper core; 2. a mica refractory layer; 3. a mica winding layer; 4. a double co-extrusion layer; 41. a waterproof layer; 42. an insulating protective layer; 5. an insulating gel layer; 6. fireproof soft ceramic chip.
Detailed Description
The present utility model will be described in further detail with reference to the accompanying drawings.
The environment-friendly cable with the copper core 1 and the polyethylene mica wound flame retardant comprises the copper core 1, wherein the section of the copper core 1 is circular, and a layer of mica fireproof layer 2 is arranged outside the copper core 1.
A mica fire-resistant layer 3 is wound on the outer side of the mica fire-resistant layer 2, and the ring diameters of the mica fire-resistant layer 3 are filled and connected through an insulating colloid layer 5, so that fire resistance and insulating performance of the mica fire-resistant layer 3 are improved.
Wherein, mica winding layer 3 divide into the multistage, is provided with a slice fire prevention soft porcelain piece 6 between the multistage mica winding layer 3, and fire prevention soft porcelain piece 6 can effectively delay the burning rate of cable, and the preferential interval 20cm sets up a slice. Meanwhile, the spacing arrangement can be carried out according to the radius of the whole cable, namely, when the cable is thicker, the spacing distance is properly prolonged. When the cable is thin, the corresponding interval is shortened.
Outside the mica winding layer 3, a double-layer co-extrusion layer 4 is arranged, wherein one layer on the inner side is a waterproof layer 41, and the other layer on the outer side is an insulating protective layer 42. The waterproof layer 41 and the insulating protective layer 42 are made of a conventional material.
The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.
