What Inspection Is Required for The Enameled Wire


    The Enameled Wire(XINYU) is the main type of winding wire. It consists of two parts: the conductor and the insulating layer. After the bare wire is annealed and softened, it is baked and repeatedly baked. However, it is not easy to consume products that meet the requirements of the specification and satisfy the customer's request. It is affected by the original data quality, process parameters, consumer equipment, environment, etc. Therefore, the quality characteristics of various enameled wires are different, but both It has four properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

    1. Appearance inspection:

    Appearance lubricated, average color, no lacquer and white smoothing agent.

    2. Dimensional inspection:

    Including enameled wire diameter, conductor diameter, enameled wire diameter, conductor error value.

    3. Mechanical characteristics:

    Including elongation, jerk, round bar winding, thermal shock.

    4. Electrical performance:

    (1) Resistance:

    Take the enameled wire to be inspected 1m, scrape the paint film at both ends, measure the resistance of the enameled wire, the resistance measurement value should be within the range of the requested resistance of GB/T6109; the standard temperature is 20 degrees, the conversion formula: 20 degrees resistance / 234.5 + specification Temperature = practical measurement resistance / 234.5 + measurement temperature;

    (2) Salt bath test

    (3) Breakdown voltage: fold the enameled wire 0.5m in half, cut off the folded part and scrape off the four lines of patent leather, then fold it twice, and twist the folded enameled wire into a twisted state. (There are two ends at each end. The head of the wire is used to test the high pressure of the two ends of the same end with a high voltage meter.
