Description

A kind of carbon fiber heating cable

Technical field

The utility model is related to field of cable technology, and in particular to a kind of carbon fiber heating cable.

Background technology

In modernization industry production, cable technology is widely used in numerous areas such as metallurgy, oil, chemical industry.And receive To the impact of environmental working condition, when being especially in field work, cable is easily chronically in adverse circumstances, and it can to need raising By property, particularly in field of petroleum exploitation, its operating environment mostly is field operating mode.Particularly in the oily recovery process of extremely frigid zones In, due to very cold, freezing phenomenon is universal, at this time, it may be necessary to heating to a certain extent is carried out to it, and it is general in prior art Copper core iron sheet being adopted logical heatable cable, due to the restriction of heating principle and structure itself, in not only needing outfit high-power more Frequency power transformer is meeting power demands, and cost is also higher.

Utility model content

The utility model aims to provide a kind of carbon fiber heating cable, to solve the above problems.

For achieving the above object, the technical solution of the utility model is as follows：

A kind of carbon fiber heating cable, it is characterised in that：The cable is disposed with from inside to outside core, internal layer protection Shell, outer insulation, armor and outer protective housing；The core includes copper conductor and Duo Gen carbon fiber heating wires, and many Root carbon fiber heating wire is mutually wrapped in outside copper conductor, and every carbon fiber heating wire is formed by many carbon fiber wire boundlings, and Every carbon fiber heating wire outer layer is enclosed with respectively inner insulating layer and waterproof layer；The armor is to be wrapped in outside outer insulation The silk screen in portion.

Further, it is also equipped with inner insulating layer outside the copper conductor.

Further, the inner insulating layer and outer insulation are polytetrafluoroethylene floor.

Further, the carbon fiber heating wire is specially four, and four carbon fiber heating wire cross sections are around copper conductor Coaxial array.

Further, the copper conductor cross-sectional diameter is 1.5-2 times of carbon fiber heating wire cross-sectional diameter.

Further, the internal layer containment vessel and outer protective housing uniform thickness.

Further, the armor is formed for zinc-coated wire concentric type is stranded.

The beneficial effects of the utility model are：The utility model is wrapped with armor in external insulation layer, and armor Specially zinc-coated wire concentric type is stranded forms, and it can effectively improve the tension of cable, anti-pressure ability, it is to avoid excessively heat expansion is cold Contracting causes the fracture of cable, improves its unfailing performance.

Secondly, the utility model is provided with carbon fiber heating wire, and carbon fiber heating wire is distributed using concentric arry, and Mutually winding, it is more balanced that one enables to heating, it is to avoid cable is heated everywhere inequality.Second, due to carbon fiber heating sheet The characteristic of body, be able to can use in low-frequency voltage, and transformer can not be used to be boosted, cost-effective.

Description of the drawings

Fig. 1 is the carbon fiber heating cable structural representation that the utility model is provided.

Mark in figure：1 is outer protective housing, 2 is armor, 3 is external insulation layer, 4 is internal layer containment vessel, 5 is carbon fiber Heater wire, 6 be copper conductor, 7 be inner insulating layer, 8 be waterproof layer.

Specific embodiment

Below in conjunction with the accompanying drawings the utility model is described further with specific embodiment.

As shown in figure 1, a kind of carbon fiber heating cable, the cable is disposed with from inside to outside core, internal layer containment vessel 4th, outer insulation, armor 2 and outer protective housing 1；The core includes copper conductor 6 and Duo Gen carbon fiber heating wires 5, and Many carbon fiber heating wires 5 are mutually wrapped in outside copper conductor 6, and the carbon fiber heating wire 5 is specially four, and four carbon fibers The cross section of heater wire 5 is around the coaxial array of copper conductor 6.Every carbon fiber heating wire 5 is formed by many carbon fiber wire boundlings, and every The outer layer of root carbon fiber heating wire 5 is enclosed with respectively inner insulating layer 7 and waterproof layer 8；The armor 2 is to be wrapped in outer insulation Outside silk screen.

Inner insulating layer 7 is also equipped with outside the copper conductor 6.The inner insulating layer 7 and outer insulation are polytetrafluoroethyl-ne Alkene layer.The cross-sectional diameter of the copper conductor 6 is 1.5-2 times of the cross-sectional diameter of carbon fiber heating wire 5.The internal layer containment vessel 4 With the uniform thickness of outer protective housing 1.The armor 2 is formed for zinc-coated wire concentric type is stranded.

When in use, external insulation layer 3 is wrapped with armor 2 to the utility model, and the specially zinc-coated wire of armor 2 is same Core type is stranded to be formed, and it can effectively improve the tension of cable, anti-pressure ability, it is to avoid is excessively expanded with heat and contract with cold and is caused the disconnected of cable Split, improve its unfailing performance.

Secondly, the utility model is provided with carbon fiber heating wire 5, and carbon fiber heating wire 5 is distributed using concentric arry, And mutually wind, it is more balanced that one enables to heating, it is to avoid cable is heated everywhere inequality.Second, due to carbon fiber heating The characteristic of itself, be able to can use in low-frequency voltage, and transformer can not be used to be boosted, cost-effective.

And, carbon fiber heating wire of the present utility model 5 and copper conductor 6 are provided with inner insulating layer 7 outside itself, also exist Outside is provided with external insulation layer 3, and its insulation effect is better, can form multiple protective, it is to avoid the injury thing that electric leakage is caused Therefore.

And carbon fiber heating wire 5 is additionally provided with waterproof layer 8 outside insulating barrier, cold cause because interior heat is outer after the heating After steam is piled up, steam can be prevented to penetrate into and cause inside heater wire short circuit.

Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
