Abstract
The utility model provides a nanometer frequency-conversion self-lubricating refrigerant-resistant enameled aluminum wire, in which the surface of an aluminum core conductor is successively coated with a first insulating layer, a second insulating layer and a third insulating layer from inside to outside. The first insulating layer includes polyester-imide insulating varnish; the second insulating layer is a nanometer quantum frequency-conversion resin layer which is formed by adding silica, alumina or other metal oxide fine power particles into polyamide-imide through a nanometer technology, wherein the thickness of the second insulating layer is 40% of that of the total insulating layers, and the second insulating layer has excellent corona resistance; and the third insulating layer includes modified self-lubricating polyamide-imide insulating varnish which enables good refrigerant resistance, good wearing resistance and lower friction coefficient of the enameled wire when being used as the surface coating. According to the utility model, the corona resistance, the refrigerant resistance, the oil resistance, wearing resistance, scratch resistance and heat resistance of the enameled wire are improved, and the nanometer frequency-conversion self-lubricating refrigerant-resistant enameled aluminum wire can be widely applied to frequency-conversion motors, motors of refrigeration compressors, high-voltage motors and high-frequency transformers.
