Abstract
The invention is concerned with the grounding pole piping heating cable, relating to the field of carbon fiber heating cable with carbon fiber, carbon fiber insulation coating and outer insulation coating. The carbon fiber is inside of carbon fiber insulation coating which is in the outer insulation coating, and the outside of the latter is lubrication coating. For binding with carbon fiber heating cable or carbon fiber electric heating cable, piping will elongate for thermal expansion, and the lubricating oil film with small friction coefficient of the heating cable forms the oily sliding friction effect, and the glue of the adhesive tape cannot work with natural conglutination effect for the oil film to solve the problem of local or whole snap. This invention is with high safety factor and long service life.
Description
Technical field
The present invention relates to the technical field of carbon fiber accompanying-heat cable.
Background technology
With carbon fiber as electric heating material, outer with plastics or rubber etc. as insulating material, can produce the carbon fiber heating cable, if at carbon fiber side plain conductor arranged side by side, then can also produce the carbon fiber electrically heating tape, usually can use the adhesive tape paper of various band glue or with the strip material of glue carbon fiber heating cable or carbon fiber electrically heating tape are not tied up and applied on pipeline, this series products is widely used in comprising various plastic conduits in the anti-freezing and heat-insulating of various pipelines.Because the coefficient of thermal expansion and contraction of plastic conduit is bigger usually, and the coefficient of thermal expansion and contraction of carbon fiber heating cable or carbon fiber electrically heating tape is smaller, coefficient of thermal expansion and contraction between the two is inequality or asynchronous, so, in the process of operate as normal, plastic conduit is because the former thereby heat expansion elongation of being heated, in the time of the plastic conduit elongation, will produce pulling force to tying up the carbon fiber heating cable or the carbon fiber electrically heating tape that apply on this pipeline, when this pulling force acts on carbon fiber heating cable or carbon fiber electrically heating tape for a long time, just may cause the fatigability part to break or all break to carbon fiber or metallic conductor, thereby cause: (1) carbon fiber is broken because of the part and is caused the local electrical resistance rate to raise, can can cause fire when serious at the unusual heat spot that raises of this local formation temperature during energising; (2) conductor of the plain conductor in the carbon fiber electrically heating tape is all broken, and causes cold fault, has influenced the normal use of product.
Summary of the invention
The object of the invention provides the pipeline accompanying-heat cable of a kind of coefficient of safety height, long service life.
The present invention includes carbon fiber, carbon fiber insulating barrier, external insulation layer, carbon fiber is arranged in the carbon fiber insulating barrier, and the carbon fiber insulating barrier is arranged in the external insulation layer, the arranged outside lubricating layer of above-mentioned external insulation layer.
When carbon fiber heating cable or carbon fiber electrically heating tape are tied up when applying on pipeline, when pipeline begins to elongate owing to heat expansion, tie up carbon fiber heating cable or the carbon fiber electrically heating tape that applies and stick together with this pipeline, because there is one deck lubricating oil film on its surface, coefficient of friction is especially little, and the sliding friction effect of formation oiliness, the existence of this sea surface oil slick simultaneously, can also allow tie up and apply the adhesion effect that the adhesive on its lip-deep adhesive tape can't be brought into normal play, so, plastic conduit just can not all act on carbon fiber heating cable or carbon fiber electrically heating tape because of the elongation pulling force that heat expansion produces, thereby has solved the local problem of breaking or all breaking effectively.The present invention has realized the purpose of coefficient of safety height, long service life.
The present invention also is provided with metal dielectric layer in above-mentioned external insulation layer, metallic conductor is set in the metal dielectric layer.
Description of drawings
Fig. 1 is the structural representation of end of the present invention.
Fig. 2 is the end construction schematic diagram of user mode of the present invention.
Embodiment
As shown in Figure 1, carbon fiber 6 is arranged in the carbon fiber insulating barrier 5, and carbon fiber insulating barrier 5 is arranged in the external insulation layer 2, the arranged outside lubricating layer 1 of external insulation layer 2.
Metal dielectric layer 3 also is set in the external insulation layer 2, metallic conductor 4 is set in the metal dielectric layer 3.
As shown in Figure 2, the present invention and pipeline 7 are close together, and by the adhesive tape paper of various band glue or carbon fiber heating cable or carbon fiber electrically heating tape are not tied up and applied on pipeline with the strip material 8 of glue, at carbon fiber heating cable or carbon fiber electrically heating tape arranged outside lubricating layer 1, owing to reduced coefficient of friction greatly, and the adhesion degree when greatly reducing the adhesion of adhesive tape paper, so when in use, the influence that carbon fiber heating cable or carbon fiber electrically heating tape are expanded with heat and contract with cold by pipeline is smaller, increase the present invention's coefficient of safety in use, prolonged useful life.
Claims (2)
1, pipeline accompanying-heat cable comprises carbon fiber, carbon fiber insulating barrier, external insulation layer, and carbon fiber is arranged in the carbon fiber insulating barrier, and the carbon fiber insulating barrier is arranged in the external insulation layer, it is characterized in that the arranged outside lubricating layer of above-mentioned external insulation layer.
