CN201741454U - 200-stage polyesterimide nonmagnetic enamelled round copper wire - Google Patents

Abstract

The utility model discloses a 200-stage polyesterimide nonmagnetic enamelled round copper wire comprising a round copper wire conductor, wherein the outer surface of the round copper wire conductor is wrapped with an insulating layer which is nonmagnetic polyesterimide paint and has the thermal level of 200 stage; and the round copper wire conductor is the copper conductor having diamagnetic performance. The round copper wire is reasonable in structure design, the round copper wire conductor used is the electrical copper conductor having higher diamagnetic performance, the insulating layer is 200-stage polyesterimide insulated paint, and the round copper wire is manufactured by special process, thus ensuring the diamagnetism index quality magnetisability Xm of the enamelled wire finally produced to be superior to 0-(-6)*10-6(cm3/g), due to the adoption of the special material and processing method, the enamelled wire has higher nonmagnetic performance, and the round copper wire can be applicable for special industries having high requirement on anti-electromagnetic interference, geomagnetic field influence and the like, such as aerospace, navigation and position system, and can be better used in serious environments such as superhigh temperature, low temperature, overloading and the like.

Description

200 grades of nonmagnetic enamelling cuprum round line of polyamidoimide

Technical field

The utility model relates to a kind of enamelling cuprum round line.

Background technology

Common enamelled wire is usually used in the coil windings of common electric machine, electrical equipment, electronic instrument, transformer, because its anti-electromagnetic interference capability is weak, unstable, can't be applicable to high sensitivity electronic instrument that special industry that antagonism electromagnetic interference, earth magnetic field have high requirements uses, high accuracy navigation system, navigation system etc.Particularly under harsh and unforgiving environments such as superhigh temperature, low temperature, more can not be suitable for.

The utility model content

The technical problems to be solved in the utility model provides a kind of 200 grades of nonmagnetic enamelling cuprum round line of polyamidoimide, can be advantageously applied to have higher anti-electromagnetic interference, the high sensitivity used of the special industry of magnetic influence, high precision navigation system, navigation system etc., can in harsh and unforgiving environments such as superhigh temperature, low temperature, overburden, use well simultaneously.

For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of 200 grades of nonmagnetic enamelling cuprum round line of polyamidoimide, comprise the copper round wire conductor, the outer surface of described copper round wire conductor is enclosed with insulating barrier, this insulating barrier is nonmagnetic polyamidoimide lacquer, its thermal level is 200 grades, and described copper round wire conductor is the copper conductor with diamagnetic performance.

Compared with prior art, the beneficial effects of the utility model are: reasonable in design, the copper round wire conductor that uses is that the electrician with higher diamagnetic ability uses copper conductor, insulating barrier is 200 grades a polyamidoimide insulating varnish, its processing technology adopts special technology to make, and guarantees that the enamelled wire diamagnetism index ' s quality magnetic susceptibility Xm of final production is better than 0-(6) * 10 ^-6(cm ³/ g), owing to adopted special material and processing method, enamelled wire has higher nonmagnetic performance, can be applicable to the special industry that antagonism electromagnetic interference, earth magnetic effect etc. have high requirements, as Aero-Space, navigation, navigation system aspect, can in harsh and unforgiving environments such as superhigh temperature, low temperature, overburden, use well simultaneously.

Description of drawings

Fig. 1 is the cross-sectional view of the utility model embodiment.

Embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

As shown in Figure 1, a kind of 200 grades of nonmagnetic enamelling cuprum round line of polyamidoimide comprise copper round wire conductor 1.The outer surface of described copper round wire conductor 1 is enclosed with insulating barrier 2, and this insulating barrier 2 is nonmagnetic polyamidoimide lacquer, and its thermal level is 200 grades.The copper conductor of described copper round wire conductor 1 for having diamagnetic performance.

Adopt aforesaid way, can solve these problems of mentioning in the background technology well, owing to adopted special material and processing method, enamelled wire has higher nonmagnetic performance, can be applicable to the special industry that antagonism electromagnetic interference, earth magnetic effect etc. have high requirements, as Aero-Space, navigation, navigation system aspect, particularly in high temperature, severe cold, extra-heavy environment, has exclusive advantage.
