Summary:

The copper clad aluminum wire is a layer of copper skin […]

The copper clad aluminum wire is a layer of copper skin outside the aluminum core, and is not an insulated wire, belonging to the bare wire type. The Enameled aluminum wire is coated with an insulating paint film on the outside of the aluminum core. It is an insulated wire and belongs to the enameled wire type. It is mainly used for motor winding coils.

Copper clad aluminum wire is outside and copper is aluminum inside.

The enameled aluminum is externally insulated and the inside is aluminum.

The enamelled aluminum wire is only made of aluminum as a conductor, and the copper clad aluminum wire has the characteristics of copper and aluminum. It combines the excellent electrical conductivity of copper and the light weight of aluminum. The conductor material mainly has the advantages of electrical conductivity. Distinguish, the following is a comparison of conductor resistivity of copper, aluminum, and copper clad aluminum:

A copper-clad aluminum wire with a length of 1 mm and a cross-section of 1 mm 2 has a resistivity of 0.02676 Ω·mm 2 /m at 20 ° C.

1 meter long aluminum wire with a cross-sectional area of 1 square millimeter, the resistivity at 20 ° C is 0.0294 Ω · mm 2 / m

A 1 m long copper wire with a cross-sectional area of 1 mm 2 has a resistivity of 0.0177 Ω·mm 2 /m at 20 ° C.
