Copper magnesium (Cu-Mg), copper silver (Cu-Ag), copper chromium zirconium (Cu-Cr-Zr) alloy are current best high-strength highly-conductive materials of generally acknowledging, particularly contain the copper magnesium alloy of magnesium 0.1 ~ 1.0 quality %; The Kufil of argentiferous 1 ~ 7.0 quality %; Contain chromium 0.1 ~ 0.8 quality %, contain the Cu-Cr-Zr alloy of zirconium 0.02 ~ 0.8 quality %.Have under hot environment, material can keep high-intensity characteristics, has very high electric conductivity simultaneously, adopt the copper alloy with high strength and high conductivity wire rod as the enamelled wire conductor material, make enamelled wire have the characteristic of high-strength highly-conductive, conductor material is not softening under hot environment, be subjected to distortion and necking can occurring after hot high pressure is impacted, enamelled wire can not be elongated in electrical equipment winding technique process, guarantees the resistivity Be Controlled of enamelled wire, makes electrical equipment obtain better stability.
Summary of the invention
For overcome existing enamelled wire in the winding technique process during easily by drawing-down, instantaneous pressure short circuit hot high pressure dash and distortion and necking can occur, conductor is defective such as softening transform under hot environment, and the utility model provides a kind of modern design, scientific and reasonable high-strength highly-conductive enamel-cover copper alloy wire.
The technical solution adopted in the utility model is:
High-strength highly-conductive enamel-cover copper alloy wire comprises conductor layer and is coated on the outer insulating barrier of conductor layer, it is characterized in that: the copper alloy wire of described conductor layer for being made by copper magnesium, copper silver or copper-chromium-zirconium alloy material.
Further, content of magnesium is 0.1 ~ 0.35 quality % in the described copper magnesium alloy; Silver content is 0.6 ~ 2.0 quality % in the Kufil; Chromium content is 0.3 quality % in the Cu-Cr-Zr alloy, and zirconium content is 0.1 ~ 0.3 quality %.
The utility model is not softening under hot environment, is subjected to distortion and necking can occurring after hot high pressure is impacted, and enamelled wire can not be elongated in electrical equipment winding technique process, guarantees the resistivity Be Controlled of enamelled wire, makes electrical equipment obtain better stability.The lead winding that the utility model flows through electric current is arranged, meaningful especially as transformer, motor etc.
The beneficial effects of the utility model are embodied in:
1, adopts the copper alloy with high strength and high conductivity wire material as the enamelled wire conductor material, under hot conditions, can keep high strength, have very high electric conductivity simultaneously;
2, in the motor windings winding process, be difficult for being elongated drawing-down, guarantee the resistivity Be Controlled of enamelled wire;
3, be subjected to distortion and necking can occurring after hot high pressure is impacted, make electrical equipment obtain better stability;
4, reasonable in design, simple in structure, the intensity height, coiling is good, and is safe and reliable.
