transformer with aluminum windings

Jul 09, 2023

The coil is the circuit part of the transformer. Commonly used materials are copper and aluminum. Traditionally, the coil made of copper is called an all-copper transformer, and the coil made of aluminum is called transformer with aluminum windings. Both There are four main differences: copper has better conductivity than aluminum, and for the same current, aluminum has a larger cross-sectional area than copper, so copper transformers are smaller than aluminum transformers; copper is heavier than aluminum and has the same power , Copper transformer is heavier than aluminum transformer; the price of copper is more expensive than aluminum.

Transformer with aluminum windings usually include transformer aluminum foil and transformer insulated aluminum wire. Transformer aluminum foil generally uses 1060 aluminum strip, which contains more than 99.6% of aluminum, has good elongation and tensile strength, and can fully meet the conventional processing requirements (stamping , Stretching) has high formability, is industrial pure aluminum, has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, and is easy to withstand various pressure processing, drawing and bending. Insulated aluminum wire usually includes enameled aluminum wire, glass-fiber coated aluminum wire, paper-coated aluminum wire, etc. Enameled wire can be divided into polyester enameled wire, polyesterimide enameled wire, polyamideimide enameled wire, polyimide enameled wire, polyesterimide/polyamideimide enameled wire, corona resistant enameled wire, and oily enameled wire according to the insulating varnish used. Paint, acetal paint, polyurethane enameled wire, etc. Sometimes it is also classified according to the particularity of its use, such as self-adhesive enameled wire, refrigerant resistant enameled wire, etc.

Aluminium Co., Ltd. specializes in the production of various transformer aluminum foils, enameled aluminum wires, glass wire coated aluminum wires, polyimide film coated aluminum wires, etc., which are exported to Japan, Italy, Mexico, Vietnam and other countries. The quality is well received by customers.
