Engineered to maximize slot fill factors and minimize core losses for Ethiopian high-performance electrical equipment.
Ethiopia is undergoing a historic shift towards industrial modernization. Centered around massive power initiatives like the Grand Ethiopian Renaissance Dam (GERD) and regional energy transmission networks, the demand for highly efficient electrical equipment is surging. Power utilities like Ethiopian Electric Power (EEP) and local private engineering hubs require premium materials to build, repair, and maintain heavy-duty transformers and industrial-grade motors.
Enameled flat copper wire (also referred to as rectangular magnet wire) is a critical raw material supporting these systems. With slot-fill properties that far exceed conventional round wires, our flat wire solutions allow manufacturing plants in Bole Lemi, Hawassa, and Adama Industrial Parks to design compact, high-efficiency equipment. Our export services are optimized for the complex logistics of East Africa, routing reliably through the Port of Djibouti to Mojo Dry Port, ensuring that local manufacturers receive raw materials on time without assembly delays.
The international power generation and industrial motor sectors are shifting rapidly toward flat wire configurations.
Traditional round wire coils leave empty gaps between wires. Rectangular design maximizes the cross-sectional area, achieving slot fill factors up to 85% for high-density power yields.
Hairpin winding technology in traction motors relies entirely on high-quality enameled flat copper wire. This global shift supports localized motor assembly and green mobility projects in East Africa.
Global motor standards like IEC IE3 and IE4 demand extremely low electrical resistance losses, driving transformer and generator manufacturers to use premium-grade flat copper wire.

Transition to 800V High-Voltage Systems: To support modern electric transportation, traction motors are upgrading from 400V to 800V architectures. This transition demands enameled wires with superior resistance to partial discharge. Our research and development center is developing next-generation polyamide-imide (PAI) and polyimide (PI) blends that can double wire lifetime under high-frequency electrical stress.
Introduction of Hybrid CCA Wires: For systems where structural weight is critical, our copper-clad aluminum (CCA) enameled wire configurations provide an optimal weight-to-conductivity balance, lowering overall component mass while matching round-wire performance metrics.
