4. Tensile strength: The maximum tensile stress that the specimen is subjected to during the tensile test. It is the most widely used and representative test for the mechanical properties of insulating materials.
5. Combustibility: refers to the ability of an insulating material to resist burning when it contacts the flame or when it leaves the flame. As the application of insulating materials is expanding, the requirements for its resistance to combustion are more important, and various methods are used to improve and improve the flame resistance of insulating materials. The higher the resistance to combustion, the better its safety.
6. Arc resistance: The ability of an insulating material to withstand arcing along its surface under specified test conditions. During the test, an alternating current high-voltage small current is used to determine the arc resistance of the insulating material by the action of an arc generated by the high voltage between the two electrodes to form a conductive layer on the surface of the insulating material. The greater the time value, the better the arc resistance.
7. Sealing degree: It is better to seal the oil quality and water quality.
