Enameled Wire


Enameled wire varnish coats copper and aluminum round and flat wires for engines, transformers, generators and electrical measuring instruments. It cures to the wire surface at high temperatures. The primary function of the final coating is electrical insulation. Enameled wire varnish can also be called primary insulation. The coated wire is sometimes referred to as “magnetic wire.”

Enameled wire varnish coats copper and aluminum wires with up to 30 layers, providing electrical insulation and helping to avoid short circuits in the coils. Such wire enamels must also have excellent chemical and high-temperature resistance, must have excellent adhesion to copper or aluminum wires, and must also have excellent mechanical stability.

This type of enameled wire is mainly used in small transformers, timers, relays, small motors, solenoid valves, clock coils, watch coils, flyback transformers and magnetic heads.

2. Solderable Polyesterimide Enameled Wire

Weldable polyesterimide enameled wire can be widely used in relays, small transformers, small motors, contactors, ignition coils and automobile coils.

3. SEC Modified Polyester Enameled Wire

SEK modified polyester enamelled aluminum wire and copper wire have good mechanical resistance, electrical resistance, chemical resistance and heat resistance.

4. SEC Polyesterimide Enameled Wire

SEK polyesterimide enameled wire has high heat resistance, good mechanical resistance, electrical resistance and chemical resistance. This type of enameled wire is widely used in motors, refrigeration equipment, transformer coils and fluorescent lamp ballasts.

5. Polyamideimide Enameled Wire

Polyamide-imide double-coated or single-coated enameled wire, both with good mechanical properties and chemical resistance. These products are particularly suitable for coating electric motors, refrigeration equipment, transformer coils and fluorescent lamp ballasts.

6. Acetal Enameled Wire

Acetal heavy round and rectangular enameled wire. It has excellent mechanical stability, excellent copper adhesion and resistance to transformer oil, so it is mainly used in large generators and transformers. In addition to good dielectric properties, this type of enameled wire varnish also exhibits excellent chemical resistance, which makes the coated wire suitable for gas-tight applications and oil-immersed transformers in accordance with IEC60 851-4 standards.


Aluminum Foil

Eugenia Tech transformer aluminium foil can be used for variable transformer like low or high voltage transformer winding, high frequency transformer,step up or down voltage transformer etc. The alloy can be used to meet the minimum industry requirements for strip conductor, is closely controlled to assure smooth, substantially burr-free edges and strip-size avail-abilities are in capacities exactly equivalent to those of standard copper wire sizes.


Copper Foil

Eugenia Tech also provide copper foil less than 150 micrometers (µm) thick.

Copper foils strips for transformers are the electrical industry’s most versatile materials, and has important advantages for winding transformer conductors.

The majority of copper foil is used in the power electronics industry, where it is used in transformers, motors and generators for the windings.

Insulated foils are used in dry-type transformers and small transformers, where they are wound together with insulating materials.
