Triple Insulated Wire, 24 AWG ETFE Reinforced Winding Wire, 155°C - 5 Spool Sizes

Triple insulated wire is a type of winding wire built around a single copper conductor with three layers of extruded insulation. Made from modified ETFE, the insulation guards the wound wire against short-circuiting, breakdown between windings, and physical damage during coil assembly. This reinforced construction achieves voltage ratings, dielectric strength, and creepage/clearance spacing that standard magnet wire cannot meet on its own. 24 AWG offers a similar balance to 22 AWG with a somewhat finer profile, suiting transformer and medical winding applications where a more compact coil is preferred. This gauge is commonly used in multi-winding transformer designs where several coils share limited bobbin space without exceeding insulation requirements. Rated for Class F service (155°C/311°F), this wire holds multiple UL/IEC/VDE compliances and insulation system approvals, suiting it to switching transformers, medical equipment, and other components with strict performance and regulatory demands.
