Abstract
The invention discloses a rubber sheathed multi-core cable with high tensile strength. The cable adopts the structure as follows: the cable includes a plurality of strand cores, a molybdenum stranded conductor is placed inside each strand core, and a copper stranded conductor is arranged outside each molybdenum stranded conductor; a hot silver coating is arranged on the surface of each molybdenum stranded conductor, and a passivation layer is arranged on the surface of the hot silver coating; an epoxy coating is arranged on the outer sides of the strand cores; an insulating sleeve is arranged on the outer sides of the strand cores in a sleeving manner; The rubber sheathed multi-core cable with high tensile strength, provided by the invention can solve the deficiencies in the prior art, improves the strength, abrasive resistance and corrosion resistance of the copper stranded conductor by adding the galvanized steel core, the epoxy coating and the insulating sleeve, and prolongs the service life of the copper stranded conductor.
Description
Technical field
The present invention relates to a kind of cable, especially a kind of high-tensile multi-core rubber sleeve cable.
Background technology
At present, for considering of cost and conductivity, cable generally adopts copper stranded conductor.But it is low that copper 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 high-tensile multi-core rubber sleeve cable, the deficiencies in the prior art can be solved, by adding copper facing steel core and epoxy coating and insulating sleeve, improve the intensity of copper stranded conductor, resistance to wear and corrosion resistance, improve the life-span of copper stranded conductor.
In order to solve the technical problems, the present invention taken by the technical scheme is as follows: a kind of high tensile elastic set of multi-core cable, stranded wire core structure includes a number of root, each core stranded wire inside to chu conductor, chu outside of the wire is copper conductor;Chu set hot silver conductor surface layer, heat setting of silver coating surface has a passivation layer, outer stranded wire core set with epoxy resin coating, lateral also set of stranded wire core is equipped with insulation casing.
Described as optimization, amount of copper coated coarse wire of 200 g/m < sup TranNum = "51" > 3 < / sup >.
As preferably, described insulating barrier is that multilayer Mica tape forms.
As preferably, described high-tensile multi-core rubber sleeve 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.
As preferably, the cold deformation of described copper stranded conductor is no more than 10%.
The invention in copper conductor on the basis of thick wire inner core, improve the tensile strength of copper stranded wire.Coarse wire of the lateral set of hot silver plating layer and the passivation layer improves the coarse corrosion resistance of the wire.The epoxy coating of copper stranded conductor arranged outside and insulating sleeve improve the corrosion resistance resistance to wear of copper stranded conductor.By choose reasonable copper facing amount, under the prerequisite ensureing corrosion resistance, decrease production cost.Twisted wire core adopts center around the arrangement mode of formula, improves the firmness of high-tensile multi-core rubber sleeve cable.
