THEIC-Polyesterimide Wire Enamels (TPEI)

THEIC-polyesterimide wire enamels, which are highly heat-resistant, offer very good mechanical, electrical and chemical resistance. These wire enamels are widely used on wires in electrical motors, refrigeration equipment, transformer windings and ballasts for fluorescent lamps.

Thanks to its very good mechanical properties, a high thermal rating and good chemical resistance, Voltatex 7300 AX is used to coat wires widely used in smaller transformers, cooling aggregates and electrical ballasts.

How to protect against corona discharges?

Corona discharges can occur in high voltage applications of electrical devices, such as inverter fed motors, transformers, high voltage rectifiers, generators, ignition coils, wind generators, hybrid motors, elevators or pump motors. The Voltron® system, whose technology has been granted a worldwide patent, comprises a basecoat and a topcoat – the Voltatex 7700 and Voltatex 8500 series. Voltron can only be used under certain conditions. Please contact us for detailed information.
