FIW4 3800V 0.18mm Class 180 Fully Insulated Copper Wire For Transformer Windings

Fully insulated wire (FIW) is a type of wire that has multiple layers of insulation to prevent electrical shocks or short circuits. It is often used for building switching transformers that require high voltage and high FIW has some advantages over triple insulated wire (TIW), such as lower cost, smaller size, better windability and solderability FIW is also approved by various safety standards
