Description
Technical field
The utility model relates to enamelled wire technical field, and specifically, the utility model relates to a kind of enamelled wire with profiled cross-section.
Background technology
The raw material that enamelled wire is changed as a kind of electromagnetic energy, in commercial Application widely, be the supporting basic material industry of electrical equipment and electrical, household electrical appliances and the industry such as electronic information, communication, market demand is very large.
In recent years, the importance and functions of enamelled wire in national economy is more and more outstanding, uses field also more and more extensive.The large multiplex fine copper of traditional enamelled wire is as raw material, although copper has good electric conductivity, greatly (8.89g/cm3), the copper of same volume is more than aluminium recuperation for the density of fine copper; Internal copper resource famine simultaneously, the copper of more than 1/2 is had to need import every year, and the density of aluminium little (2.7g/cm3), lightweight, but poorly conductive, mechanical strength are low, flexibility is poor, and easily generate the pellumina with insulation property, in addition, the fire protecting performance of enamelled wire is poor, therefore those skilled in the art need badly provides a kind of enamelled wire with profiled cross-section, optimize the structure of existing enamelled wire, not only improve current-carrying performance, possess well anti-oxidation and fire protecting performance simultaneously.
Utility model content
In order to solve the problem of prior art, the utility model provides a kind of enamelled wire with profiled cross-section, optimizes the structure of existing enamelled wire, not only improves current-carrying performance, possesses well anti-oxidation and fire protecting performance simultaneously.
The utility model patent provides a kind of enamelled wire with profiled cross-section; comprise insulator and conductor; the cross section of described insulator comprises at least two annular solids; connected by transverse connection between described annular solid; for holding a conductor in each annular solid; described conductor by multiple copper core and thread core of aluminum stranded with strand form, the outside of described conductor is coated with protection against oxidation layer and fire resistant coating successively, is provided with screen in described transverse connection.
Preferably, the both sides of described screen are respectively equipped with for fire-retardant oxygen barrier layer.
Preferably, the thickness of described oxygen barrier layer is 0.2-0.5mm.
Preferably, described copper core and thread core of aluminum are spaced.
The beneficial effect that the technical scheme that the utility model provides is brought is: the enamelled wire of what the utility model provided have profiled cross-section; compare existing enamelled wire and optimize its structure; adopt compound copper-aluminium wire simultaneously; improve current-carrying performance; reduce cost; possess good anti-oxidation function by the protection against oxidation layer arranged, combustibility, retardance rapidly the spreading of fire of enamelled wire can be reduced by fire resistant coating, the fire endurance of enamelled wire can be improved.
