Significant properties Directly solderable without any prior mechanical stripping of the enamel at the temperature:
- 0,050 mm at 350 - 370 °C in 1"
- 0,500 mm at 380 - 400 °C in 2"
Due to a good surface smoothness and copper softness is excellent for the wire windings requiring high filling factor.
Good thermal resistance (180 °C)
Good mechanical resistance.
Excellent resistance to sizing of epoxied and polyamide resins.
Good mechanical resistance.
High thermal resistance (180°C)
Self-solderable wire:
Ø 0,050 mm at 450 ÷ 470 °C in 2 ”
Ø 0,280 mm at 480 ÷ 500 °C in 2 ”
Low percentage of extraction with perchloroethylene and chloride solvents in general.
High resistance to solvents.
Excellent winding characteristics due to the high resistance to abrasions and to the good surface smoothness.
Excellent thermal resistance (>200° C).
Very high resistance to impregnating varnishes and to humidity.
Very low percentage of extraction with perchloroetylene with Danfoss method.
Excellent resistance to transformers oil.
Recommended applications Is especially suitable for applications requiring automated soldering systems: small trasformers, small motors, measuring equipements, impregnated and unimpregnated coils operating at a max. temperature of 180 °C Motors, transformers, electromagnetic coils and in general electrical assemblies working at high temperatures up to a maximum of 180 °C. Motors, hermetic compressors motors, oil filled transformers, ballasts and in general electric assemblies operating at very high temperature up to 200 °C
