SynWire – Winding Wires SynWire V 155, copper wire, round, enamelled
- Solderable enamelled round cu.wire
- Insulated with polyurethane
- Class 155
SynWire V 155 is a thermal class F enamelled copper wire which can be directly soldered. The most outstanding characteristic of this wire is the possibilty of having an efficient and safe contact of the wire ends by fast and easy solderability with a solder bath temperature from 390 °C upwards without prior mechanical removal of the insulation film. This type of enamelled copper wire fulfills the requirements of modern winding technology.
State-of-the-art process technology ensures excellent formability, high elongation and good insulating properties. The chemical resistance to aggressive, fluid or gaseous media is limited; therefore, compatibility tests are recommended prior to application.
Application
transformers, relays, contactors, solenoid coils, small motors
Standards
IEC / DIN EN 60317-20
NEMA MW 79-C
UL approved
Delivery forms
Grade 1+2: 0.036 – 1.7 mm
