CLASS 220 0.9MM*0.4MM RECTANGULAR ENAMELED COPPER WIRE SQUARE MAGNET WINDING WIRE
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, reduce skin effect effectively, decrease current loss, that's better to adpat high frequency transduction.
High space factor and fill in ratio, greatly reduce 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, stable good 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 high 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 application
