¡ñConductor resistance. Measured with a conductor resistance tester, and then changed to the value at 20¡ãC for comparison.
¡ñ Dielectric breakdown voltage. Twist two enameled wires, apply voltage between their conductors, and judge by the breakdown voltage of the paint film. The performance is analyzed and judged by two tests of normal state and cold state breakdown voltage.
¡ñContinuity of paint film (pinhole). Check the paint film pores with a certain length of test material. This item is tested by the high pressure paint film continuity tester.
¡ñFlexibility (flexibility). When winding or elongating, judge whether the paint film is cracked or whether pinholes are generated.
