Abstract

The utility model discloses a 240-stage polyesterimide enamelled round copper wire comprising a round copper wire conductor, wherein the round copper wire conductor is wrapped with an insulating layer; lubricating liquid is coated outside the insulating layer which is polyesterimide paint having the capabilities of radio resistance, overload and ultralow temperature resistance and the thermal level of 240 stage; and the round copper wire conductor is a round copper wire with high purity. The round copper wire is reasonable in structure design, the copper wire used is the electrical round copper wire with high purity, the insulating layer is polyesterimide paint having the capabilities of radio resistance, overload and ultralow temperature resistance, due to the adoption of the 240-stage polyesterimide insulating paint used in special environments, the enamelled wire has excellent thermal shock resistance, radio resistance, overload and ultralow temperature adaptive functions, and can be applicable for special industries such as aerospace, nuclear power, space satellites and the like, especially applicable for the superhigh temperature state.

Description

240 grades of polyimides enamelling cuprum round line

Technical field

The utility model relates to a kind of copper round wire.

Background technology

Common enamelled wire is usually used in the coil windings of common electric machine, electrical equipment, electronic instrument, transformer, its temperature resistant grade general all 220 grades and below, for superhigh temperature resistant, radioresistance, overburden enamelled wire that special purpose needs, the prior art level generally can only provide the highest 220 grades of thermal level enamelled wires.

The utility model content

The technical problems to be solved in the utility model provides a kind of 240 grades of polyimides enamelling cuprum round line, and this enamelled wire can use under environment such as superhigh temperature resistant, radioresistance, overburden, as high-tech areas such as nuclear reactor, Aero-Space, Aerospace Satellites.

For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of 240 grades of polyimides enamelling cuprum round line, comprise the copper round wire conductor, described copper round wire conductor is wrapped with insulating barrier, insulating barrier scribbles one deck lubricating fluid outward, described insulating barrier is the polyimide varnish with radioresistance, excess load, anti-ultralow temperature ability, and its thermal level is 240 grades, and described copper round wire conductor is highly purified copper round wire.

Compared with prior art, the beneficial effects of the utility model are: reasonable in design, the copper cash that uses is that highly purified electrician uses copper round wire, insulating barrier is the polyimide varnish with radioresistance, excess load, anti-ultralow temperature ability, owing to adopted 240 grades of polyimide insulative lacquers that are exclusively used under the particular surroundings, enamelled wire has good heat shock resistance, radioresistance, excess load, ultralow temperature adaptive functions, can be applicable to some special industries, as aspects such as Aero-Space, nuclear energy, Aerospace Satellites, particularly adapt to the superhigh temperature state.

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 240 grades of polyimides enamelling cuprum round line comprise copper round wire conductor 1.Described copper round wire conductor 1 is wrapped with insulating barrier 2, the insulating barrier 2 outer lubricating fluids 3 that scribble the special use of one deck enamelled wire.The polyimide varnish of described insulating barrier 2 for having radioresistance, excess load, anti-ultralow temperature ability, its thermal level is 240 grades.The copper round wire that described copper round wire conductor 1 is used for highly purified electrician.

The enamelling cuprum round line that adopts the foregoing description to design, have good heat shock resistance, radioresistance, excess load, ultralow temperature adaptive functions, can be applicable to some special industries,, particularly adapt to the superhigh temperature state as aspects such as Aero-Space, nuclear energy, Aerospace Satellites.
