Enameled wire is a wire material that is wound by an insulated coil and covered with an enameled insulation layer. The coating adhesion of enameled wire refers to the degree of adhesion between the insulating layer of the enameled wire and the metal conductor, which is crucial to ensure the performance and safety of the wire.

Cladding adhesion testing is a series of tests to evaluate the adhesion strength between the insulation layer of the enameled wire and the conductor. The following is a detailed description of a common cladding adhesion testing method:

Sample preparation: Peel off a small section of the enameled wire to be tested to expose the metal wire and ensure that the length of the sample is sufficient for testing.

Test equipment preparation: Prepare a tensile testing machine that can measure the changes in the sample when the force is applied. Ensure equipment is calibrated and meets test requirements.

Clamp the sample: Clamp both ends of the enameled wire sample into the clamps of the tensile testing machine respectively, ensuring that the clamps can firmly clamp the sample to prevent the sample from sliding or falling off during the test.

Applying force: Set a fixed pulling force speed on the tensile testing machine and start applying the pulling force. The amount of pulling force depends on the required testing requirements and standards.

Record test data: During the test process, the tensile tester records the tensile force exerted on the sample. At the same time, any abnormal conditions, such as sample slipping or breakage, should also be recorded.

Analysis results: After completing the test, the cladding adhesion of the enameled wire can be evaluated based on the test data. Typically, adhesion is evaluated based on the magnitude of the tensile force applied and the behavior of the specimen. If the adhesion between the insulation layer of the sample and the wire is strong, the sample will slide or break under higher tensile force.

This is a common cladding adhesion testing method and the actual test steps and parameters may vary due to different standards and requirements. Before conducting any testing, ensure that applicable standards and safe operating procedures are followed.
