Custom FTIW 0.21mm*7 155°C Polytetrafluoroethylene Membrane ETFE Teflon Litz Wire
Product Description
One of ETFE's key advantages is its high dielectric strength, enabling the insulation to withstand a breakdown voltage of up to 14,000V. This makes extruded ETFE stranded wire particularly suitable for high-voltage transformers and other critical electrical equipment, ensuring reliable performance and safety.
