The main properties of the magnet wire, including:

    Mechanical properties: the wire insulation should be appropriate flexibility, softness and elongation, the film should be uniform, smooth, resistant hanging around the insulation resistance drag mill, in order to ensure that the insulation of the conductors in the winding production process exposed to a variety of mechanical stress effects.

    2, the electrical properties: the coating of the insulating layer to completely winding insulation can not leak package film pinhole less, high breakdown voltage, high frequency, high voltage when the loss tangent is small, tolerance and resistivity of the wire size shall comply with the requirements of the national standard.

    3, the thermal performance: Requires an insulating layer to meet the temperature requirements for heat-resistant grade, higher softening breakdown strength, thermal aging and thermal shock performance is better.

    And chemical properties: the insulating layer should be able to acid, alkali, salt and fog, organic solvents or refrigerant chemicals such as erosion, the film should have a strong anti-benzene solvent corrosion.
