Abstract
The invention discloses a crosslinking insulation power cable. The crosslinking insulation power cable structurally comprises a plurality of stranded wire cores, wherein a steel stranded wire is arranged in each stranded wire core and is wrapped with an aluminum stranded wire; a thermal silver-plating layer is arranged on the surface of each steel stranded wire, a passivation layer is arranged on the surface of each thermal silver-plating layer, an epoxy resin coating is arranged outside the stranded wire cores which are sleeved with an insulation sleeve, and the insulation sleeve comprises an insulation layer and a thermal insulation layer. The crosslinking insulation power cable can eliminate defects in the prior art; the strength, the abrasion resistance and the corrosion resistance of the aluminum stranded wires are improved and the service life of the aluminum stranded wires are prolonged due to additional arrangement of galvanized steel cores, the epoxy resin coating and the insulation sleeve.
Description
Technical field
The present invention relates to a kind of cable, especially a kind of cross linked insulation power cable.
Background technology
At present, for considering of cost and conductivity, cable generally adopts aluminium stranded conductor.But it is low that aluminium stranded conductor exists tensile strength, the shortcoming of resistance to wear and corrosion-resistant, the life-span is generally on the low side.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cross linked insulation power cable, the deficiencies in the prior art can be solved, by adding zinc-plated steel core and epoxy coating and insulating sleeve, improve the intensity of aluminium stranded conductor, resistance to wear and corrosion resistance, improve the life-span of aluminium stranded conductor.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of cross linked insulation power cable, and structure comprises some twisted wire cores, and the inside of every root twisted wire core is steel strand wire, and the outside of steel strand wire is aluminium stranded conductor; Steel strand surface is provided with hot dip silver layer, and hot dip silver layer surface is provided with passivation layer, and twisted wire core arranged outside has epoxy coating, is also arranged with insulating sleeve outside twisted wire core, and described insulating sleeve has insulating barrier and thermal insulation layer to form.
As preferably, the zinc-plated amount of described steel strand wire is 200g/m
3.
As preferably, described insulating barrier is asbestos layer.
As preferably, described cross linked insulation power cable is made up of 19 twisted wire cores, and a twisted wire core is positioned at center, and the twisted wire core at all the other 18 twisted wire Xin Yi centers is that the center of circle is evenly distributed.
As preferably, described thermal insulation layer is aluminium oxide.
The present invention adds steel strand wire inner core on the basis of aluminium stranded conductor, improves the tensile strength of aluminium stranded conductor.The hot dip silver layer of steel strand wire arranged outside and passivation layer improve the corrosion resistance of steel strand wire.The epoxy coating of aluminium stranded conductor arranged outside and insulating sleeve improve the corrosion resistance resistance to wear of aluminium stranded conductor.By the zinc-plated amount of choose reasonable, under the prerequisite ensureing corrosion resistance, decrease production cost.Twisted wire core adopts center around the arrangement mode of formula, improves the firmness of cross linked insulation power cable.
