ENAMELED COPPER WIRE HIGHLY HEAT RESISTANT FOR ELECTRIC MOTOR WINDING
Thick wires usually are coated with a sort of enamel that is very tough, an excellent insulator, highly heat-resistant, highly resistant to solvents, and that clings to copper even better than dirt does to children! This enamel is usually yellowish clear, so that the wire coated in it looks mostly copper-colored, but many exceptions exist. To solder the ends of these wires, it’s necessary to scrape off the enamel, using a sharp knife or similar tool. This procedure would be too difficult with a thin, fragile wire, so that these thin wires are instead covered with an enamel that has most of the same characteristics of the other one, except the heat resistance: It will melt and turn into solder flux at a temperature a common soldering iron easily achieves! This allows easily soldering these wires, without previously stripping them. But transformers using this latter kind of wire enamel cannot survive temperatures as high as those using only the former kind of wire enamel. The red wire on the right side in this photo has this kind of enamel. But be careful with colors! The clear wire on the extreme left side also has solderable enamel, while the dark violet one in the middle is of the non-melting variety!
FEATURES AND BENEFITS
1. Very good solderability that can be soldered without removal of coating.
2. Small tg δ value under high frequency electronic apparatus.
3. Easy to be dyed to different colors for identifying purpose when soldered.
APPLICATIONS
- For power generation : Coil for electromagnetic switches, solenoid coil, Coil for lighting fixtures
- Coil-micro-motor, electric fan, transformer
- Small type motor ( Electric household appliance, Toys & etc. )
- Transformer for measuring instrument
