Other types of insulated conductors, such as glass fiber insulation copper/aluminum alloy round and flat wire with varnish, Nomex insulated copper/aluminum round flat wire, kraft paper, insulated copper/aluminum round flat wire, mica insulation copper/aluminum round flat wire , kapton insulated copper/aluminum round flat wire and polyester film insulating copper/aluminum round flat wire is widely used in various applications, such as motor, transformer and reactor, etc.
The characteristic of corrosion-resistant enamelled copper wire/enamelled aluminum wire makes them attractive in these devices because of their corrosion resistance. Enamelled aluminum and copper wires are preferred materials for circuits because they last a long time.
The mechanical, electrical and chemical properties of enamelled aluminum wires differ from copper wires due to the inherent differences in conductor materials. These differences are reflected in certain test procedures and/or performance requirements for the aluminum enamelled electromagnetic wire, such as elongation, adhesion and flexibility, thermal shock, scratch resistance, continuity and heat resistance.
Aluminum enamelled winding wire has the advantage of light weight. This product is widely used in electric tools, ballasts, automotive electronics, refrigerator and air conditioner compressor motor, TV set, electric furnace, microwave ovens, all kinds of transformer and other kinds of electronic coil motors, electrical appliances.
Enamelled aluminium wire is sometimes used in large transformers and motors, but due to its low conductivity, the cross-sectional area of the enameled aluminium wire must be 1.6 times that of copper wire to achieve comparable dc resistance. Smaller diameter electromagnetic wires usually have circular cross – sections. Thicker aluminum magnetic lines are usually square or rectangular (with rounded corners) to allow more efficient use of available winding space.
Enameled Aluminum Wire have wide applications, such as dry type transformer, stator winding grading and overall HP motor, dc field and the armature winding, motor used for sealing, hand tools, chemical industry, boiler and high torque, continuous rated, all electrical appliances machine motor, automotive electronics, coil applications – go up lacquer paint or not. Enamelled aluminium wire or sealed-grade enamelled copper wire is ideal for refrigeration and air-conditioning systems.
