Product Description

  Wholesale Transformer Special Enamelled Aluminium Wire

        Enameled wire is a type of conductive metal wire with a surface coated with an insulating enamel layer. Its core function is to fulfill the dual requirements of electrical conductivity and insulation in electromagnetic equipment — it not only needs to transmit electric current to generate electromagnetic fields, but also to prevent short circuits between adjacent wires. It serves as the core "nervous system" for electromagnetic components such as electric motors, transformers, inductors, and relays.

       According to the conductor material, it can be divided into copper enameled wire, aluminum enameled wire, and composite conductor enameled wire.

Copper Enameled Wire

The most commonly used type, with conductors made of pure copper (electrolytic copper). It has excellent conductivity (high electrical conductivity), good mechanical strength, and strong corrosion resistance, suitable for most scenarios (such as motors, transformers, precision coils). According to hardness, it can be divided into hard state (for shaped windings) and soft state (for flexible winding).

Aluminum Enameled Wire

 The conductor is aluminum, whose cost is significantly lower than that of copper (about 1/3 of copper). However, its conductivity is relatively low (about 60% of copper), and surface treatment is required to improve weldability. It is mostly used in low-cost, low-power equipment (such as small fan motors, economical transformers).

Composite conductor enameled wire

Combining the advantages of different metals, such as copper-clad aluminum (aluminum core + copper outer layer, balancing low cost and conductivity) and copper-clad steel (steel core + copper outer layer, enhancing tensile strength), it is suitable for specific scenarios such as high-frequency coils and lead wires.

According to the shape of the conductor, it can be divided into round enameled wire and flat enameled wire.

Round enameled wire

The conductor has a circular cross-section, with a simple winding process and low cost. Its space utilization rate (fill factor) is approximately 70%. It is a general-purpose choice and is widely used in small motors, inductors, relays, etc.

Flat enameled wire

The conductor has a rectangular (flat) cross-section, with high space utilization (the duty cycle can reach more than 90%), better heat dissipation and mechanical strength. It is suitable for high-voltage motors, large transformers, reactors and other equipment with high requirements for space and performance.
