Upgrade your high-capacity electrical engineering projects with Rational – DC Enamelled Copper Strips. Specifically designed to replace standard round wires in dense, heavy-duty machinery, these flat rectangular conductors maximize copper volume while offering superior dielectric protection. Combining an ultra-pure copper base with a high-performance dual-coat formulation, these strips provide heavy industrial equipment manufacturers with a reliable, space-saving solution that comfortably handles large current volumes without thermal breakdown.

Quality Maintain Every Time
Flat profiles present unique insulation challenges, which is why our quality monitoring focuses strictly on corner-radius film integrity. Every production batch runs through automatic inline thickness gauges to ensure the enamel depth is completely uniform around sharp corners and flat faces alike. We execute specialized heat-aging tests along with high-pressure wrap-around checks, guaranteeing that the dual-coat system maintains absolute adhesion and zero peeling when bent at acute angles during coil fabrication.
Engineered for Maximum Current Density
Pack more power into highly confined spaces. The flat, rectangular cross-section of these strips entirely eliminates the empty air gaps inherent to round wire clusters, providing an exceptionally high slot fill-factor. This geometric efficiency allows for maximum current density within the stator or core slots, significantly enhancing the magnetic flux output and overall operating efficiency of large-scale industrial generators.
Exceptional Resistance to Edge Flaking
Say goodbye to insulation tearing during heavy-duty strip forming. Our specialized curing process ensures that the dual-coat protective layer stretches perfectly over the rectangular edges without thinning out or flaking off. The tough outer polyamide skin provides a slick, abrasion-resistant barrier that can withstand the intense mechanical pressures of heavy winding jigs, pneumatic forming hammers, and automatic bending machinery.
High Thermal Dissipation in Sealed Coils
Prevent dangerous heat buildup inside tightly packed, multi-layered windings. Because flat surfaces allow for direct, face-to-face contact between individual turns, these strips dissipate heat far more effectively than round alternatives, sending thermal loads outward toward the cooling ducts. Combined with a robust dual-coat formulation, this superior heat dissipation capability safeguards the insulation layer against premature aging, degradation, and localized hot-spot burnouts.
