EmTherm CR
EmTherm CR, is a Corona Resistant enamelled copper wire, belonging in C (220°C) thermal class, able to be manufactured in the diameter range of 0.50 – 2.20 mm with three different insulation layers.
Providing thermal resistance up to 220°C, EmTherm-CR possess the feature of being winded at high speeds and is resistant against corona effect. Produced specially for inverter driven motors, it has a life time up to 10 times longer.
Fields of Use:
- Inverter driven motors
- Traction motors
- Power bridges
- Semi-hermetic compressor motors
