Von Roll - Enameled Rectangular Wires
Von Roll produces a complete range of enameled rectangular copper wires according to IEC 60317-0-2 and NEMA dimension ranges, with Grade 1 or Grade 2, according to IEC or Quad, Heavy builds according to NEMA. Duroflex® / FormvarEnameled wire with a coating featuring outstanding mechanical properties, mainly for windings in oil transformers and electrical counters.
Thermex® / HPAM / HDT-3000High-temperature wires with temperature indices up to 240°C. Chemistries are modified polyesterimide, polyamide-imide and aromatic polyimide (original Pyre-ML). The improved bonding resulting from nickel plating on the copper core significantly enhances their resilience when subjected to high temperature and radiation.
Thermibond®Self-bonding wires mean that motor or generator manufacturers do not need to use impregnation varnishes, thus reducing manufacturing time cycles. Two grades with different bonding strengths allow optimal fixation of the wires without damaging the enamel.
AustraShield®Corona discharge-resistant enameled wires for use in inverter driven motors. Lifetime under corona-discharge conditions for AustraShield® is 200 times higher than for standard enameled wires.
