Enameled Copper Clad Aluminum Wire

Production Characteristics

• 

  1. ECCA has an aluminum core with copper cladding and an insulating enamel coating. Conductor resistivity depends on copper volume fraction and material quality; DC resistance also depends on conductor area and length.

• 

  2. The copper surface can support suitable termination methods after enamel removal. Copper cladding does not make the enamel directly solderable. Use a qualified stripping and termination process; direct soldering requires a specifically qualified solderable enamel system.

• 

  3. Density, winding weight and cost depend on copper cladding ratio, conductor dimensions and the winding design. Compare alternatives at the required resistance, current capacity and temperature rise.

• 

  4. Available thermal classes: 130, 155 and 180. Thermal performance is determined by the qualified insulation system; aluminum does not automatically provide a higher thermal class than copper.

• 

  5. Flexibility and winding performance depend on conductor temper, diameter, cladding integrity, enamel flexibility and processing conditions. Validate the selected ECCA wire for the intended winding.

• 

  Insulation: ELANTAS

Main Technical Tests

Technical tests and acceptance limits depend on conductor diameter, copper cladding ratio, enamel build and insulation system and are agreed in the product specification.
