Abstract
A power cable, whose sheath is covered with a plastic conductive layer, comprises a conductor (1), a shielding layer of the conductor (2), an insulating layer (3), a shielding layer of the insulating layer (4), a semi-conductive resisting water expansion layer (5), a metal sheath and anti-corrosion layer (6), a plastic sheath (7), from the cable center to the outside in turn, a plastic conductive layer (8) doped with carbon black which is sheathed outside of the sheath (7) to form a firm adhesion between the plastic conductive layer and the sheath. The conductive layer without dust pollution, desquamation and environment pollution, whose surface is smooth, level, uniform and continuous, exhibits high mechanical strength, excellent wear resistance, and reliable performance as well as low worker's labor intensity and high production efficiency.
Description
The utility model relates to the improvement of power cable structure, is the improvement that high pressure, superhigh pressure are failed the power cable structure of using in the modified line road specifically.
At present, the power cable that uses in high pressure, the defeated modified line road of superhigh pressure generally adopts following structure: power cable, from cable center outwards be successively, conductor, conductor shield, insulating barrier, insulation screen, the semiconductive water-proof and expanding layer, metallic sheath and anticorrosive coat, plastic sheath and graphite powder conductive layer, under 170 ℃ of conditions of high temperature of graphite powder conductive layer employing when extruding polyvinyl chloride or vinyon sheath, make with artificial one deck semiconductive graphite powder that applies.This graphite powder conductive layer, and the adhesion property between the sheath is poor, comes off easily, and the easy contaminated environment of graphite powder adopts artificial the coating in addition, and the surface is uneven, and labor strength is big.Before the utility model design is finished, not seeing the power cable identical with the utility model structure as yet uses in actual life, not seeing the power cable identical with the utility model structure has sale, and it is on the books in the literature also not see the power cable identical with the utility model structure.
The purpose of this utility model is to provide a kind of sheath to be coated with the power cable of plastics conductive layer, the adhesion-tight between plastics conductive layer and sheath, this conductive layer no dust pollution, do not come off, free from environmental pollution, adopt the extruder expressing technique to make, conductive layer surface is smooth, and is smooth, evenly, continuously, the mechanical strength height, anti-wear performance is good, dependable performance, and labor strength is low, the production efficiency height.
For achieving the above object, the utility model adopts following technical proposals:
Sheath is coated with the power cable of plastics conductive layer, from cable center outwards is conductor, conductor shield successively, insulating barrier, insulation screen, semiconductive water-proof and expanding layer, metallic sheath and anticorrosive coat, plastic sheath is coated with the plastics conductive layer that one deck is mixed with carbon black at sheath.
The plastics of said plastics conductive layer can be polyethylene or polyvinyl chloride.
The thickness of said plastics conductive layer can be 0.1 millimeter to 2.0 millimeters.
The outer plastics conductive layer of sheath adopts the extruder expressing technique to make, and plastics conductive layer and sheath are extruded simultaneously.
The utility model has more following effects and good effect:
Because the power cable that the utility model provides a kind of sheath to be coated with the plastics conductive layer forms firm adhering to, this conductive layer no dust pollution between plastics conductive layer and sheath, do not come off, free from environmental pollution, conductive layer surface is smooth, smooth, evenly, continuously, the mechanical strength height, anti-wear performance is good, dependable performance, and labor strength is low, the production efficiency height.
Below in conjunction with accompanying drawing structure of the present utility model is described in further detail:
Fig. 1 is a structure cross sectional representation of the present utility model.
In the drawings,
The 1st, conductor, the 2nd, conductor shield, the 3rd, insulating barrier, the 4th, insulation screen, the 5th, semiconductive water-proof and expanding layer, the 6th, metallic sheath and anticorrosive coat, the 7th, sheath, the 8th, plastics conductive layer.
Sheath is coated with the power cable of plastics conductive layer, from cable center outwards is conductor 1, conductor shield 2 successively, insulating barrier 3, insulation screen 4, semiconductive water-proof and expanding layer 5, metallic sheath and anticorrosive coat 6, plastic sheath 7 is coated with the plastics conductive layer 8 that one deck is mixed with carbon black at sheath 7.
The plastics of said plastics conductive layer 8 can be polyethylene or polyvinyl chloride.
The thickness of said plastics conductive layer 8 can be 0.1 millimeter to 2.0 millimeters.
Claims (3)
1. a sheath is coated with the power cable of plastics conductive layer, from cable center outwards be successively, conductor (1), conductor shield (2), insulating barrier (3), insulation screen (4), semiconductive water-proof and expanding layer (5), metallic sheath and anticorrosive coat (6), plastic sheath (7) is characterized in that being coated with the plastics conductive layer (8) that one deck is mixed with carbon black at sheath (7).
