Description

A high temperature resistant waterproof cable

【Technical field】

The utility model relates to a cable, in particular to a high temperature resistant waterproof cable.

【Background technique】

The use of cables is very extensive. In some specific places, due to the special environment, cables need to be laid in high-temperature water, which requires the cables to have high-temperature resistance and waterproof performance. The current cable products generally only have waterproof performance or high-temperature resistance. meet specific usage needs.

【Content of utility model】

The technical problem to be solved by the utility model is to provide a high temperature resistant waterproof cable, which not only has the performance of high temperature resistance but also has the performance of waterproof.

The utility model is achieved in that:

The utility model is a high-temperature-resistant waterproof cable, which comprises from the inside to the outside in turn: a cable core formed by twisting an insulating wire core and a waterproof filling rope, and a waterproof isolation layer formed by a first waterproof belt wrapped around the cable core. The polyolefin material is used as the sheath layer; the insulated wire core includes: a conductor, a second waterproof tape wrapped around the conductor, and a fluoroplastic insulation layer from the inside to the outside.

Further, each conductor is formed by twisting multiple wires, and the gaps between the multiple wires are filled with waterproof yarn.

The utility model has the advantages of:

The conductor gap of the utility model is filled with waterproof yarn, the conductor is wrapped with a second waterproof tape, and the outer periphery of the cable core is provided with a waterproof isolation layer formed by the first waterproof tape, so the cable has a good waterproof effect;

The utility model uses fluorine plastic as the insulating layer of the insulating wire core, and uses polyolefin material as the sheath layer, so that the cable has good high temperature resistance;

The utility model is simple in structure, convenient and practical.

【Description of drawings】

The utility model will be further described below in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is the structural representation of the utility model.

【Detailed ways】

Referring to Fig. 1, the utility model embodiment is described in detail.

As shown in Figure 1, an embodiment of the utility model includes: a cable core 1 twisted with an insulated wire core 11 and a waterproof filling rope 12; The isolation layer 2 is a sheath layer 3 made of polyolefin material; the insulated core 11 includes: a conductor 111 , a second waterproof tape 112 wrapped around the conductor 111 , and a fluoroplastic insulating layer 113 . The conductor 111 is formed by twisting multiple wires, and the gaps between the multiple wires are filled with waterproof yarn (not shown).

The utility model comprises five insulated wire cores 11, the interior gap of the conductor 111 in the insulated wire core 11 is filled with waterproof yarn, the conductor 111 is wrapped with a second waterproof tape 112, and the periphery of the cable core 1 is provided with a first waterproof tape Formed waterproof isolation layer 2, so the cable has a good waterproof effect, and the utility model uses fluoroplastics as the insulating layer 113 of the insulating core 11, and uses polyolefin material as the sheath layer 3, so that the cable has good high temperature resistance .

The above is only a preferred embodiment of the utility model, so the scope of implementation of the utility model cannot be limited accordingly, that is, the equivalent changes and modifications made according to the patent scope of the utility model and the contents of the specification should still belong to this utility model. within the scope of utility models.
