Class 130/155/180/200/220 enamelled coated Aluminum magnet wire
Performance comparison of enamelled wires :
The space factors of magnet wires are compared in the right figure. The space factors of enamelled wires are superior to those of other wires for winding, as are their electrical properties. However, more careful examination must be made of the following properties as compared with other wires.
(1) Heat resistance
(2) Resistance to solvents, chemicals and varnishes
(3) Resistance to hydrolytic degradation
(4) Stability when combined with insulating materials
(5) Resistance to water and moisture
(6) Ease of use
