Solution Enamel Aluminum Heating Problem


    Solving the Causes and Solution of Enameled Aluminum Wire Heating. Xinyu Enameled Aluminum Wire are insulated wires used to make coils or windings in electrical products. Also known as the winding wire. The enameled wire must meet the requirements of various uses and manufacturing processes. The former includes its shape, specifications, ability to work at high temperatures for short and long periods of time, and withstands strong vibrations in certain occasions and centrifugal forces at high speeds, withstands corona and breakdown at high voltages, and with chemical resistance under special atmospheres. Corrosion, the latter includes the requirements of being subjected to stretching, bending and abrasion during winding and weaving, as well as swelling and erosion during dipping and drying.

    Xinyu Enameled aluminum wire can be classified according to their basic composition, conductive core and electrical insulation. Generally, it is divided into an enameled wire, a wrapped wire, an enamel wrapped wire, and an inorganic insulated wire according to the insulating material and the manufacturing method used for the electrical insulating layer.

    In the application process, the temperature of the electromagnetic coil will gradually rise and then become hot. If the cooling measures are not taken in time, the electromagnetic coil is likely to be burnt. Let's take a look at the causes and solutions for the heating of the electromagnetic coil.

    In the case of an AC electromagnet, the enameled aluminum wire temperature rises in addition to its own resistance, and because the temperature of the core rises. If there is an induced current in the core of the alternating magnetic field, some of the electric energy will be lost, and the temperature of the iron core will rise accordingly. The induction cooker uses this principle to increase the temperature. Since the coil is wound around the iron core, its heat is reduced after it is transmitted to the coil. In order to amplify the induced current loss in the iron core, the AC electromagnet is similar to the transformer, and it is better to use the mutual component. The insulating steel sheet is used as the iron core, and the loss of the coil is enlarged, and the temperature of the coil can be lowered.
