Solderable fully insulated (FIW) zero-defect enamelled round copper wire, class 180, with a single coating based on polyurethane resin, which may be modified providing it retains its chemical identity and satisfies all the required technical specifications.
FIW is defined with many Grades specifying different insulation thicknesses. Reduction in the number of grades of FIW from 3 through 9 to 4, 6 and 8 only; – reduction of the wire diameter range from (0,040 to 1,000) mm to (0,090 to 0,900) mm for several requirements
FIW is produced in a multiple coating process, which guarantees insulation without any defects.
FIW enameled wires are a group of fully insulated wires with high puncture resistance. It belongs to the group of materials with reinforced insulation. Undoubtedly, the advantage of this insulation is its high puncture resistance. The declared value of the electric strength depends on the thickness of the insulation.
