3.46mm represents the wire diameter or gauge of enameled insulated aluminum wire. This is a dimensional indication of the cross-section of the conductor, which is used to determine the size and capacity of the wire. This enameled insulated aluminum wire uses aluminum as the conductor material, which has good electrical conductivity and is suitable for electrical transmission and applications.

Enameled insulated aluminum wire has an insulating layer, usually achieved by coating the surface of the aluminum conductor with an insulating varnish. The purpose of the insulation is to provide electrical insulation protection against short circuits or electric shocks between wires or between wires and other objects.


Enameled insulated aluminum wire is commonly used in the internal connections and windings of generators. The windings of a generator are a critical part of converting electrical energy into mechanical energy, so using the right wire is critical to the performance and efficiency of the generator; aluminum wire has a lower heat capacity compared to copper wire. Under high loads or prolonged operation, enameled insulated aluminum wire may be more susceptible to heat and may result in elevated temperatures.

Due to the lower heat capacity of aluminum wires, enameled insulated aluminum wires may be more susceptible to heat under high loads or prolonged operation. Therefore, the heat dissipation system and design of the generator needs to take into account the thermal characteristics of the aluminum wire to ensure that the wire does not overheat and maintains normal operating temperatures.

Enameled insulated aluminum wire may not be suitable for use in some special environments, especially in high humidity, corrosive environments or high temperatures. Aluminum can react chemically with certain substances, which may cause the wire to corrode or oxidize, affecting electrical performance and reliability. Therefore, when using enameled insulated aluminum wire in special environments, appropriate protective measures are required.
