Special Enamelled Wire

Aluminum Enamelled Wire( Aluminum Enamelled Wire)

Although copper being the major conductor for today’s enamelled wire market, while users demanding some special requirements of function (such as: lower production-cost, lighter product-weight and the lower temperature-rising during motor operation, etc.), needing different conductor materials; like aluminum, to satisfy the various utilities in the electronic or electrical industries.

In response to the change in market demand, the Aluminum (AL) and Copper Clad Aluminum (CCA) and other special conductors become the new alternative materials for the enamelled wire.
