- Jan 23, 2018 -

A test of high temperature enameled wire is more important. Its surface is smooth, its color is uniform, and it has no varnishes and white lubricant.

Quick pull: the standard is at the speed of 2 meters per second, the test film is not cracked, and the round rod is coiled: the enameled wire of different specifications is wound around ten times with the corresponding copper rod, and the paint film is not cracked.

Thermal shock: the coil is wrapped in the oven (suspended in the middle of the oven) for 0.5 hours, and the temperature of the oven is the corresponding specification of enameled wire.
