Excuse me, does anyone know what the general voltage resistance of enameled wire is?

General enameled wire withstand voltage is1:1000-2000 v; Secondary: 1900-3800V. The withstand voltage of enameled wire is related to specifications and paint film grade. See GB/T 6 109. 1 -2008 standard (part 1 of general terms for enamelled round winding wires) for details.

Enamelled wire consists of conductor and insulating layer. The bare wire is annealed and softened, and then painted and baked many times. Enamelled wire is the main raw material of motor, electrical appliances, household appliances and other products. Especially in recent years, the power industry has achieved sustained and rapid growth, and the rapid development of household appliances has brought more extensive applications to enamelled wires, which puts forward higher requirements for enamelled wires.

Extended data

When the enameled wire is detected, the sensor and the enameled wire do not contact in the whole process, which will not cause additional damage to the enameled wire. There are many burrs in the formed steel wire core, which may be caused by the raw material itself or the drawing process. Another reason may be uneven paint, impurities in paint, the quality of paint itself, and drying after painting.

Pinhole defect detection is based on the principle of high voltage discharge, and the electromagnetic wire is in semi-envelope contact with the concave wheel applied with high voltage. When the film thickness is insufficient or bare copper defects are serious, the instrument will record the number of specific defects. Motor manufacturers should pay special attention to this performance, because this defect can easily lead to motor failure and seriously affect the service life of the motor.

In the past, people used off-line detection methods such as voltage mercury method, Japanese brine method and low-voltage electrolyte method to detect the continuity of paint film. These methods are not suitable for on-line detection of enameled wire in production process.
