Extra Fine Magnetic Copper Wire Class 180 Good Conductivity For Watch Coils

Enamelled resistance wires have found increasing use in Electrofusion fittings. The heating wires can move as the polymer in the fitting melts at the fusion points when they are energised, causing the heating effect to be distorted. This can cause the fitting to 'fail' it's fusion cycle which is monitored by the controller/power source. Some designs also require the wire to cross over a flat coil, greatly increasing the chances of shorting. Class 200 enamel provides just enough insulation for the electrofusion process without significantly affecting the heat transfer characteristics of the system.

RUIYUAN was established in 2002, located in Tianjin City,the second largest port city in China.We have been focusing on different kinds of high quality wires: enameled round copper wire, rectangular enameled copper triple insulated wire, silk covered Litz wire, bonding wire and special enameled wire for 21 years.Ruiyuan is one of the pioneers in producing micro thin enameled wires below 0.03mm in China. Our R & D team has 20 years of market experience. In 2019, our finest diameter is 0.011mm, and mass production has been achieved. All of our products are UL, RoHS certified, in line with industry standards IEC60317, JIS C 3202, NEMA, NW82.
