CLASS 220 3.50mm * 0.40mm SUPER THIN RECTANGULAR ENAMELED COPPER
WIRE FLAT COATED COPPER WIRE FOR MOTOR WINDING
Meet design requirement of lower height, smaller size, lighter and
more power. The wire is widely used in electronics, electric
application, motor, network communication, smart home, new energy,
automobile electronic, medical electronic, military electronic,
spaceflight.
Bigger surface area than round wire at the same cross section,
recduce skin effect effectively, decrease current loss, that’s
better to adpat high frequency transduction.
High space factor and fill in ratio, greatly recduce resistance,
pass bigger current, get higher Q value that is better to adapt
high current load.
The product that use rectangular wire has such features: simple in
structures, good heat dissipation, stable performance, stablegood
consistency. Maintain stable temperature rise current and
saturation current in high frequency and high temperature
environmnet anti EMI, small vibration, low noise and install in
gigh density.
APPLICATIONS
1) 120 degree flat enameled wire for oil-immersed transformer
2) 130,155,180 degree flate enameled wire are widely used in all
kinds of magnet coil
3) 200 degree flat enameled wire works constantly in high
temperature
4) 240 degree flat enameled wire for magnet coils of
aviation,military and marine appication
