Abstract
The utility model discloses a 200-class polyester-imide/polyamide compound enameled round copper wire which comprises a copper conducting wire, wherein a first insulating layer is coated on the surface of the copper conducting wire, a second insulating layer is coated on the surface of the first insulating layer, the first insulating layer is polyester-imide paint with the thermal class being 200, and the second insulating layer is polyamide insulating paint. By adopting the structure, the enameled round copper wire can be applicable to higher working environmental temperature and better thermal shock resistance, simultaneously has excellent electrical insulation performance, lower friction coefficient, good thermal resistance, abrasion resistance and better electrical insulation performance and greatly improves the production efficiency. The 200-class polyester-imide/polyamide compound enameled round copper wire can be widely applied in production of enameled round copper wire coil windings with higher requirement on the thermal resistance for automobile engines, wiper motors, motorcycle motors and the like; and a lubricant is coated on the surface of the second insulating layer, thereby having good lubrication and abrasion resistance.
Description
Technical field
The utility model relates to enamelling cuprum round line, especially a kind of 200 grades of compound enamelling cuprum round line of polyester-imide/polyamide.
Background technology
Conventional polyester imines enamelling cuprum round line is usually used in common electric machine, electrical equipment, electronic instrument, the coil windings of transformer, its temperature resistant grade is 180 grades, for automobile, motorcycles etc. are gone up the motor that uses and are required temperature resistant grade higher, heat-resistant impact ability is stronger, can adapt to coiling at a high speed and reduce the wearing and tearing of coil rack enamelling cuprum round line, the requirement of increase production cost that simultaneously can not be too much, common polyester-imide enamelling cuprum round line is because the skin-friction coefficient height, wear no resistance, there is certain limitation in thermal endurance simultaneously, also do not fit into coiling at a high speed and produce, production efficiency is lower.
The utility model content
The utility model technical issues that need to address are to provide a kind of 200 grades of compound enamelling cuprum round line of polyester-imide/polyamide, this enamelling cuprum round line can be applicable to that the motor that automobile, motorcycle etc. upward use requires temperature resistant grade higher, the requirement that heat-resistant impact ability is stronger, simultaneously the surface has lower coefficient of friction, resistance to wear preferably, can adapt to the high speed needs that wind the line.
The technical solution of the utility model is: a kind of 200 grades of compound enamelling cuprum round line of polyester-imide/polyamide, comprise copper conductor, described copper conductor surface is coated with first insulating barrier, this first surface of insulating layer is coated with second insulating barrier, described first insulating barrier is the polyester-imide lacquer, its thermal level is 200 grades, and described second insulating barrier is a polyamide insulating varnish.
As preferably, described first insulating barrier and second insulating barrier are molten to be one.
As preferentially, described second surface of insulating layer also is coated with lubricant.
The beneficial effects of the utility model are: enamelling cuprum round line of the present utility model has two insulating barriers, first insulating barrier is than 180 grades of better 200 grades of polyimide varnishs of polyester-imide thermal endurance, can adapt to higher operating ambient temperature and better heat-resistant impact ability, have good electrical insulation properties simultaneously; Second insulating barrier is for being the insulating varnish of main component with the polyamide; and molten with first insulating barrier be one; have lower coefficient of friction, good thermal endurance, resistance to wear and electrical insulation properties preferably; can improve the resistance to wear of product greatly and lower coefficient of friction is provided, can adapts to high speed and wind the line; raising promotes production efficiency to the electrical insulation properties protection of enamelling cuprum round line.The utility model can be widely used in automobile engine, rain shaving electrical machine, motorcycle motor etc. has the enamelling cuprum round line coil windings of requirements at the higher level to produce to thermal endurance.And owing to better thermal endurance that it had, electrical insulation properties, littler skin-friction coefficient, also can be extensive use of other various electrical equipment and electricals; Scribble lubricant at second surface of insulating layer, make it have good lubricity and resistance to wear.
