Abstract
The utility model belongs to the field of the electric wire and cable, particularly a high conductive coating which can be served as the outer electrode of the high-voltage test. The high conductive coating is composed of non-metal electric conducting materials, organic binding agents and organic solvents. The high conductive coating has the firm adhesive with the cable, the film-forming is uniform, and the surface resistivity is smaller than 1000 omega. The cable of the high conductive coating can satisfy the requirement that the voltage is directly applied on the protective sheath while in leaving factory and completion test.
Description
The utility model belongs to the electric wire field, relates to a kind of cable with high conductive coating specifically.
Insulation or sheath for cable require to possess that the excellent electric insulating energy is arranged, and use to guarantee cable security.For checking its integrality, use the method for spark test.It is used that this method is only applicable to the intermediate mass control in process of production of cables manufacturing factory.For sheath the extra-high-tension cable of electrical insulation capability requirement is arranged, then require to soak withstand voltage test or the external electrode of semiconducting coating as withstand voltage test is set on sheath.Because a large amount of cable water tests are very inconvenient, therefore adopt usually both the dispatched from the factory usefulness of test of semiconducting coating is set on the sheath, make the completion test after the cable laying again, to add alcohol by graphite powder formulated and now be used for semi-conductive paint on the cable cover(ing).After being applied to cable surface, coating surface is uneven, and is easy to come off as shown in Figure 1, thereby causes cable surface resistance very big, can not satisfy actual use.
The purpose of this utility model provides had a kind ofly both possessed high conduction performance, and the coating of cable cover(ing) peripheral hardware is smooth, can not come off, and surface resistivity is less than the high conductive coating cable of 1000 Ω.
For finishing the technical scheme that above-mentioned purpose is taked: the sheath appearance at cable applies high conduction and the ganoid coating of being made up of non-metallic conducting material, organic bond and organic solvent, wherein non-metallic conducting material can be selected graphite or graphite and carbon black for use, organic bond can be selected perchloro-ethylene lacquer, ethene one acrylic lacquer for use, and organic solvent can be selected ketone, cyclohexanone, oxolane, toluene, dimethylbenzene for use.
Coating of the present utility model and cable have firm adhesiveness, and film forming is even, what is more important: the cable of this coating can satisfy the requirement that directly applies voltage when factory and completion test on sheath.
The utility model embodiment is described in detail in conjunction with the accompanying drawings.
Fig. 1 is prior art constructions figure;
Fig. 2 is a structure chart of the present utility model.
According to shown in Figure 2, high conduction and ganoid coating 3 that the outer surface coated of the high polymer sheath 1 in cable metal sheath or metal armouring is made up of non-metallic conducting material, organic bond and organic solvent, this coating 3 can be made the withstand voltage test external electrode, above-mentioned non-metallic conducting material is made up of graphite and carbon black, organic bond can be selected for use by perchloro-ethylene lacquer, ethene one acrylic lacquer etc., and organic solvent can be selected acetone, cyclohexanone, oxolane for use.Toluene, dimethylbenzene.Do not come off through implementing this coating fingerprint, the cripping test coating is not split, and film forming thickness 0.1-0.2mm, sheet resistance number are less than 1000 Ω, and coating surface can bear mechanical grinding or polishing simultaneously.
Claims (4)
1, a kind of by being extruded in the coat composed high conductive coating cable of cable metal sheath or metal armouring upper jacket peripheral hardware, high conduction and smooth surface coating 3 that the outer surface coated that it is characterized in that sheath 1 is made up of non-metallic conducting material, organic bond and organic solvent.
2, high conductive coating cable according to claim 1 is characterized in that non-metallic conducting material is made up of graphite and carbon black.
