Triple insulated wire 155℃ 0.1mm*250 ETFE/PTFE Copper Litz Wire For Transformer
The conductors are insulated with ETFE (ethylene tetrafluoroethylene), a high-performance polymer known for its excellent heat and chemical resistance. ETFE is rated for temperatures up to 155°C, ensuring the conductors perform effectively in a variety of harsh conditions. The thinner walls of the winding wires allow for efficient use of space, making them particularly suitable for primary applications in multi-conductor configurations.
