Advantages of Enameled Aluminum Wire

Lightweight
The density of aluminum is approximately one-third that of copper. Under the same specifications and length, enamel-coated aluminum wire is significantly lighter than copper counterparts, facilitating transportation and installation.

Cost-Effective
Aluminum is relatively lower in price compared to copper. Adopting enamel-coated aluminum wire reduces production costs, offering substantial advantages in cost-sensitive applications.

Abundant Resources
Aluminum is one of the most abundant metallic elements in the Earth's crust, with stable supply chains that support large-scale production demands

Satisfactory Electrical Performance
While aluminum's conductivity is inferior to copper, proper design optimizations and process improvements enable enamel-coated aluminum wire to meet the requirements of many electrical devices. Additionally, it exhibits excellent corrosion resistance.

Superior Insulation
The insulating enamel coating provides effective protection against short circuits and electrical leakage, ensuring the safe operation of electrical equipment.

Application of Enameled Aluminum Wire

Enameled wires are widely used in various fields such as electrical and electronic industries. The following are some of the main application scopes:

Motor Field

● Various Electric Motors: For example, three-phase asynchronous motors used in industry and single-phase motors used at home. The stator and rotor windings wound with enameled wires are key components for motors to achieve the conversion of electrical energy into mechanical energy.

● Generators: Whether it is a small wind turbine generator or a large thermal power or hydropower generator, enameled wires are required to make the windings to realize electromagnetic induction power generation.

Transformer Field

• Power Transformers: They are used for voltage transformation and electrical energy transmission in the power system. The primary and secondary windings wound with enameled wires can achieve the conversion between different voltage levels.

• Electronic Transformers: In electronic devices, such as the high-frequency transformers in switching power supplies, enameled wires are used to make the windings to achieve functions such as voltage transformation and isolation.

Electrical Instrument Field

• Relays: The coils wound with enameled wires are an important part of relays. By energizing to generate a magnetic field, they control the opening and closing of the contacts to achieve the on-off control of the circuit.

• Sensors: For some sensors, such as inductive sensors, the coils wound with enameled wires are used as sensitive elements. The change of physical quantities is measured by detecting the change of the inductance of the coils.

Electronic Equipment Field

• Audio Equipment: For example, the voice coils in speakers and headphones are wound with enameled wires. Through the force exerted on the current in the magnetic field, they drive the diaphragm to vibrate and produce sound.

• Communication Equipment: Components such as radio frequency coils and filters in communication equipment like mobile phones and base stations often use enameled wires for winding, which are used to realize functions such as signal transmission, reception and filtering.

Other Fields

• Electromagnetic Cranes: The electromagnetic coils wound with enameled wires generate a strong magnetic field to lift heavy objects such as steel, realizing the handling and loading/unloading of materials.

• Induction Cookers: The internal heating coils are wound with enameled wires. Through the alternating current, an alternating magnetic field is generated, causing eddy currents at the bottom of the cookware to generate heat.
