2. Characteristics are as follows:
- Inner oxidized electrical contact owns excellent consistency, tiny
oxidized material particle, arc corrosion resistance and long
electricity lifespan.
- Adding nickel and thulium to AgSnO2, AgSn02In2O3, AgZn02, AgCu0,
AgCd0, improves their mechanical strength, ameliorate fusion, arc
corrosion resistance and abrasion.
- make high quality contact material with the advantage of grain thin
and organization uniformity
3. Application: (widely used in low and high voltage electrical appliance.)
- AgSnO2, AgSnO2In03 series: widely used in AC contactor (CJ20, CJ40, 3TF and more) power AC
switch (≥50kW), DC contactor, AC/DC power relay, automobile and low
voltage circuit breaker.
- AgSnO2 series: widely used in low voltage circuit breaker with rating, electricity
within 200A drive socket, protective socket, AC relay DZ5L series
breaker. Some large capacity switches also use AgZnO materials such
as ME omnipotence breaker.
4. Manufacturing and test equipment
- inner oxidized electrical contact include intermediate frequency
melting furnace,
- hot mill and precision mill machine, auto-stamping machine, ionic
contamination test system AAS/WF10,
- colored microscope from Japan.
5. Packing and delivery
Inside: vacuum plastic bag
Outside: carton
According to customers' request
Delivery: within 15 days
