EmTherm CRPLUS
EmTherm CRPLUS is an advanced Corona Resistans enamelled copper wire coated with polyamide enamel over new generation corona, belonging to C (220°C) thermal class, with diameters between 0.20 and 3.60 mm.
Providing thermal resistance up to 220°C, EmThermCRPLUS, possess the feature being winded at high speeds and longer lifetime up to 50 times due to new generation nano-particle corona enamel produced through nanotechnology.
Fields of Use:
Inverter driven motors
Power transformers
Semi-hermetic compressor motors
Power bridges
