Why Aluminum Rectangular?

  • ~40% lighter than copper — reduces core weight
  • Excellent cost efficiency for large windings
  • Grade 2 insulation ensures high dielectric reliability
  • Better thermal dissipation in rectangular form
  • High space factor for transformers & reactors

Rectangular Advantage

Rectangular wires maximize copper/aluminum fill factor in confined slot spaces, reducing winding losses. Our EIWL series is specifically designed for large power transformers, traction motors, and high-current inductors.

Standard grade 2 build provides robust insulation for voltages up to several kV.


Aluminum vs. Copper — Strategic Choice

Aluminum magnet wire offers significant weight savings (approximately 40% lighter than copper for the same ampacity) and lower material cost, making it ideal for large-scale transformers, wind turbine generators, and industrial motors. With proper design (larger cross-section), aluminum windings perform reliably at 180°C thermal class. CHINGCUNG's advanced coating ensures excellent adhesion and uniform insulation even on rectangular profiles.
