Advantages of copper clad aluminum enameled wire and difference with copper wire

The existence of copper clad aluminum enameled wire actually greatly facilitates our lives. Copper clad aluminum enameled wire is an indispensable product when using electrical appliances. Even copper clad aluminum enameled wire has become an important equipment for power transmission lines. Technology research and development has always been valued by the industry

Advantages of copper clad aluminum enameled wire

  1. Light weight: With the same wire diameter, its density is 1/2.5 of pure copper wire, reducing the weight of the coil. Use copper clad aluminum enameled wire instead of copper wire to reduce cost and waste.
  2. DC resistivity: Copper clad aluminum enameled wire is 1.45 times that of pure copper wire in DC resistivity; so when the resistance value is the same, its weight is much lighter than pure copper wire.
  3. Good solderability: Because its surface is coated with a layer of pure copper, it has the same solderability as pure copper wire, and it does not need special treatment like aluminum wire.

The difference between copper clad aluminum wire and pure copper wire

There are some differences between copper-clad aluminum wire and pure copper wire. Compared with pure copper wire, copper-clad aluminum wire saves metal copper resources, and the demand for copper resources can be reduced correspondingly, which greatly reduces the cost of production. . At the same time, copper-clad aluminum wire is used to replace pure copper, thereby saving limited resources, so that copper-clad aluminum wire can be produced in large quantities. Copper clad aluminum wire also improves the stability and reliability of coaxial cable signal transmission. Coaxial cables often use aluminum as the outer conductor.

The expansion coefficient of copper-clad aluminum wire is closer to that of aluminum than pure copper, which reduces the connection failure caused by the mismatch of the expansion of the inner and outer conductors of the cable due to temperature changes. Fuda Electrical Technology manufacture enameled copper wire, aluminum wire and OEM solution such as copper clad aluminum enameled wire. The copper clad aluminum wire is light in weight and low in density, which is convenient for transportation and installation, and greatly reduces the labor intensity in network construction. This is the difference between the copper clad aluminum wire and the pure copper wire and the advantage reflected in the use.
