01 / ADVANCED TECHNOLOGY

Foil Winding Technology

Automated Foil Winding for Uniform Current & High Short-Circuit Strength

Graycell utilizes state-of-the-art automated LV foil-winding machines. By replacing conventional round/rectangular wire with continuous metal foil strip across the full width of the coil, uniform current distribution and high short-circuit withstand capability are achieved.

Key Benefits & Capabilities

Uniform current distribution throughout the winding length
High mechanical strength against axial short-circuit electromagnetic forces
Significant reduction of hot spots & superior thermal dissipation
Precision automated winding process eliminating human error
Improved long-term transformer reliability & extended service life
