Abstract
A conductor of a soft type high-voltage EPT insulated cable with light coating of the utility model adopts a compact soft aluminum structure with high intensity and high elongation which is treated by high annealing and longtime heat preservation. The cable extrudes a conductor shielding layer, an insulating layer and an insulating shielding layer on a conductor in the way of three-layer co-squeeze. The conductor shielding layer, the insulating layer and the insulating shielding layer are made of a high grade soft type high-voltage EPT material that is cross-linked with high-temperature high-pressure nitrogen and added with a compounding agent. The insulating shielding layer is covered with a layer of high wear-resisting high anti-reared chloroprene material which is vulcanized in high pressure molten salt as a sheath. The surface of the sheath is covered with a layer of micron order ultra-smooth electric shallow layer which is solidified in infrared light. The utility model is excellent in high conductivity, long in service life, ultra-smooth in surface and good in bending property, and the model can normally run in alternating intense magnetic field.
Description
Affiliated technical field
The utility model relates to a kind of cable, especially a kind of shallow layer soft type high pressure second third insulated cable.
Background technology
At present the twisted polyethylene cable that generally uses adopts crosslinked polyetylene insulated, polyvinyl chloride or pe sheath structure.This cable bending property is poor, easily burns under the strong magnetic field action that replaces, and useful life is short,
Summary of the invention
The purpose of this utility model provides a kind of shallow layer soft type high pressure second third insulated cable that possesses excellent high conductivity, long service life, super-smooth surface, good bending property, can work under strong magnetic field action alternately.
The technical solution of the utility model is: with the three-layer co-extruded shielding of mode coating conductor, insulation, insulation shielding, and coat sheath on insulation shielding on conductor, at last at jacket surface coated with conductive shallow layer.
Conductor described in the utility model is to press soft aluminium structure through high strength, high-elongation that high annealing, long-time insulation are handled.
The conductor screen that coats in three-layer co-extruded mode described in the utility model, insulation and insulation shielding adopt in three-layer co-extruded with crosslinked high pressure resistant soft type second third material of high-quality of high temperature, high pressure nitrogen and the compounding ingredient of interpolation again and are made.
Sheath described in the utility model adopts high abrasion, the high anti-tear polychloroprene material that vulcanizes again in the high pressure fused salt when coating.
Polychloroprene material described in the utility model is made by the compounding ingredient of neoprene and interpolation.
Conduction shallow layer described in the utility model adopts the micron order that solidifies with infrared light again when applying, the electrically-conducting paint of ultra-smooth to be made.
The beneficial effects of the utility model are: because aluminium conductor uses after high annealing, long-time insulation, the intensity and the elongation of conductor are greatly improved, and have also improved the softness and the bending property of cable simultaneously.Conductor screen, insulation and insulation shielding are after high temperature, high pressure nitrogen are crosslinked, increased the ampacity of cable, improved the operate power of cable, insulation becomes space network by original linear macromolecule structure, cannot not change moltenly insoluble performance into by original fusible solubleness, this has not only improved the working temperature and the overload capacity of cable greatly, the useful life of also having improved product simultaneously.Sheath is after the sulfuration of high pressure fused salt, and same is space network by original linear macromolecule structural transformation, also cannot not change moltenly insoluble performance into by original fusible solubleness, and this has improved the working temperature and the useful life of cable equally greatly.The conduction shallow layer of cable surface through can close attachment behind the infrared curing on jacket surface and very smooth, hard, anti-wear performance is splendid.Because of this coating as thin as a wafer, reach micron order, thereby do not influence the softness and the bending property of cable.Because this coating has electric conductivity, the induced current that cable surface is produced can in time be led ground again, can guarantee that like this cable is alternately normally moving in the strong magnetic field circumstance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, conductor, 2, conductor screen, 3, insulation, 4, insulation shielding, 5, sheath, 6, the conduction shallow layer.
Embodiment
The utility model is as shown in drawings: conductor 1 adopts through high annealing, and high strength, the high-elongation of long-time insulation press soft aluminium structure.Adopt three-layer co-extruded mode to extrude conductor screen 2, insulation 3 and insulation shielding 4 successively on conductor 1 surface, conductor screen, insulation, insulation shielding are to be made with high temperature, the crosslinked compounding ingredient by high pressure resistant soft type second third material of high-quality and interpolation of high pressure nitrogen in three-layer co-extruded again.Coat one deck sheath 5 on insulation shielding 4, this sheath is that the polychloroprene material that the compounding ingredient of high abrasion, high anti-tear neoprene and the interpolation of vulcanizing with the high pressure fused salt again when coating is made is made.Coat one deck conduction shallow layer 6 on sheath 5 surfaces, this conduction shallow layer is that the micron order that solidifies with infrared light again when applying, the electric conducting material of ultra-smooth are made.
