Enameled/Enamelled overcoated Round Aluminium Wire for motor rewinding
Enamelled aluminum round wire is a type of winding wire made by electric round aluminum rod which drawn by dies with special size, then over coated with enamel repetitiously.Enamelled
Round Aluminum Wire is a fundamental part of a winding in every electrical machine or apparatus. Compared to fibrous insulations, enamelled aluminium wire offers a favourable space
saving factor together with a high level of breakdown voltage. The main application of Enamelled Enamelled Aluminium wire is in winding of Motor and Transformers.

Enamelled Aluminium Wire is a wire coated with a thin layer of enamel (varnish) insulation
to prevent the wire surfaces from being in a short circuit when wound into coils. Magnetic
flux is created when current flows through the coil. Aluminum Enameled Wire is used mainly in
the construction of motors, electromagnets, transformers and inductors. For ease of manufacturing inductive components like transformers and inductors, most of these wires can be
soldered.
Enameled Aluminum Wire,also called "Magnet Wire," is widely used in various Electrical Applications due to its superior Electrical, Thermal and Mechanical Properties. Enameled Aluminium Wire is insulated by coating it with enamel of different temperature class. Enamelled Aluminum Wire are primarily used in three types of applications - in transformers to transform one kind of electrical energy into other kinds. Aluminum Enameled Wire is used in motors to transform electrical energy into mechanical energy. Enamelled Aluminium Winding Wire is also used in generators to transform mechanical energy into electrical energy.
Material :
Drawing or extruding bare (aluminum ) wire confirm to national standard, smooth surface, no defects .Good performance insulation varnish, polyester or polyester-imide insulation varnish as underlying coat, Polyamide-imide as superimposed coating.
The advantages of Enamelled round aluminum wire :
1. Compared with the copper enameled wire, enameled aluminum wire is easier to winding, also there is a solid oxide film on the surface of enameled aluminum wire, which make it has a good insulating effect, a long life.
2. Due to the good insulating effect of aluminum film layer, it's heatresistant temperature can be 20 degrees higher than the copper wire;
3. Thegreatest benefit of using aluminum is that it is 1/3 lighter than copper which significantly lower the production costs, second it can attach to the solids easily, and third it can also reduce the freight and transportation during the operation.
Features of Enameled Round Aluminum Wire :
Low density allows coil weight reduction
Rapid heat dissipation
High cut through
Excellent heat shock
Perfect breakdown voltage
High heat resistance
Good solvent resistance
