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.
Referring to fig. 1-4, in an embodiment of the present utility model, a cable comprising a plurality of strands is characterized in that: comprises an aluminum core 1; the aluminum core 1 is provided with a plurality of aluminum cores; a plurality of aluminum cores 1 are annularly arranged around the hemp ropes 6; glass fibers are filled in the filling cavities 5 among the aluminum cores 1;
by adopting the technical scheme, when the cable is used, a plurality of aluminum cores 1 are uniformly distributed around the hemp rope 6, so that the multi-strand composition of the cable is realized, and the transmission force of the cable is higher;
an insulating layer 2 is arranged outside the aluminum core 1; the insulating layer 2 is made of high-resistance materials.
Through adopting above-mentioned technical scheme, when the equipment, pack the glass fiber in the position between aluminium core 1 and insulating layer 2 fills chamber 5, prevent that aluminium core 1 from taking place the skew condition in insulating layer 2's inside for the cable loses more energy when transmitting.
In this embodiment, the insulating layer 2 is provided with a high temperature resistant layer 3 on a side far away from the aluminum core 1; the high temperature resistant layer 3 is made of a material with high temperature resistance and high fire resistance.
By adopting the technical scheme, as the high temperature resistant layer 3 is made of materials with high temperature and fire-proof grade, the heat generated in the cable transportation process can be ensured not to melt the protective layer outside the aluminum core 1 or generate open fire due to high temperature.
The high temperature resistant layer 3 is provided with a waterproof layer 4 at one side far away from the insulating layer 2; the waterproof layer 4 is a waterproof vulcanization sleeve made of vulcanized rubber;
the insulating layer 2, the high temperature resistant layer 3 and the waterproof layer 4 are concentrically arranged.
The working principle of the utility model is as follows: when the aluminum cable is used, the aluminum cores 1 are uniformly distributed at the positions around the hemp ropes 6, and glass fibers are filled in the filling cavity 5 between the aluminum cores 1 and the insulating layer 2, so that the aluminum cores 1 are prevented from being displaced in the insulating layer 2, and more electric quantity loss is prevented;
the high temperature resistant layer 3 arranged outside the insulating layer 2 can prevent the heat generated by the cable during transmission from thermally fusing the external protective layer, prevent the condition of open fire from occurring when the temperature is too high, and greatly protect the cable;
the waterproof layer 4 is arranged outside the high temperature resistant layer 3, so that the cable can be ensured to be damaged by effectively preventing external moisture from entering the cable when the cable is used, and the aluminum core 1 is damaged.
