Electrical performance:
Insulation resistance: The insulation resistance of 200-grade polyesterimide enameled aluminum flat wire should reach a certain value to ensure that the current does not leak to the outside, thereby ensuring the safe operation of electrical equipment.
Breakdown voltage: It has a high breakdown voltage value and can maintain stable electrical performance under high voltage load without insulation damage.
Voltage resistance: It can maintain stable electrical performance under continuous high voltage load without insulation aging or damage.
Polyesterimide paint
High heat resistance: It can maintain stable insulation performance for a long time in an environment up to 200°C, which is especially important for electrical equipment in high temperature working environments.
Enhanced mechanical strength: It can enhance the overall mechanical strength of the wire, including tensile strength, bending resistance, etc., making the wire more durable during processing and use.
Wear resistance and corrosion resistance: It has good wear resistance and corrosion resistance, can resist chemicals and mechanical wear in the external environment, and extend the service life of the wire.
Strong adhesion: The adhesion between polyester imide paint and aluminum flat wire conductor is strong, which can ensure that there is no falling off or cracking during the coating and baking process, ensuring the quality and reliability of the product.
