Abstract
The invention discloses an insulated control cable. The structure comprises a plurality of stranded wire cores, wherein a copper strand wire is arranged in each stranded wire core, and an aluminum strand wire is arranged outside each copper strand wire; a hot dip galvanized layer is arranged on the surface of each copper strand wire, a passivation layer is arranged on the surface of each hot dip galvanized layer, an epoxy resin coating is arranged on the outer side of the stranded wire cores, the outer side of the stranded wire cores is further sleeved with an insulation sleeve, and the insulation sleeve comprises an insulation layer and a heat insulation layer. The insulated control cable disclosed by the invention can overcome the deficiencies in the prior art; by adding galvanized steel cores and the epoxy resin coating, as well as the insulation sleeve, the strength, the wear resistance and the corrosion resistance of the aluminum strand wires are improved, and the service life of the aluminum strand wires is prolonged.
Description
Technical field
The present invention relates to a kind of cable, especially a kind of insulation control 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 insulation control 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 insulation control cable, and structure comprises some twisted wire cores, and the inside of every root twisted wire core is copper stranded conductor, and the outside of copper stranded conductor is aluminium stranded conductor; Copper stranded conductor surface is provided with hot galvanized layer, and hot galvanized 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 copper stranded conductor is 200g/m
3.
As preferably, described insulating barrier is that multilayer Mica tape forms.
As preferably, described insulation control 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 mineral wool layer.
The present invention adds copper stranded conductor inner core on the basis of aluminium stranded conductor, improves the tensile strength of aluminium stranded conductor.The hot galvanized layer of copper stranded conductor arranged outside and passivation layer improve the corrosion resistance of copper stranded conductor.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 insulation control cable.
