Quality Shielded contact box KYN61 Manufacturers china tells you that insulating materials will undergo physical phenomena such as polarization, conductance, dielectric heating, and breakdown under the action of an electric field. Quality Shielded contact box KYN61 Manufacturers china tells you that while bearing the action of the electric field, it is also affected by mechanical, chemical, and many other factors. The long-term operation will cause aging. Therefore, many failures of electrical products often occur in the insulation part.

Quality Shielded contact box KYN61 Manufacturers china tells you that the aging of the dielectric refers to the phenomenon that the electrical and mechanical properties of the dielectric gradually deteriorate with time during long-term operation. The main aging forms are electrical aging, thermal aging, and environmental aging. 1) Electrical aging. It is more common in high-voltage electrical appliances, and the main reason is that partial discharge occurs in insulating materials under high voltage.
(2) Thermal aging. Quality Shielded contact box KYN61 Manufacturers china tells you that it is more common in low-voltage electrical appliances, and its mechanism is under the action of temperature. The internal components of the insulating material are oxidized, cracked, deteriorated, and hydrolyzed with water to gradually lose their insulating properties. (3) Environmental aging. Also known as atmospheric aging, it is polluting chemical aging caused by ultraviolet rays, ozone, salt spray, acid-base, and other factors. in. UV light is the main factor. Ozone is produced by corona or partial discharge from electrical equipment.
Through the above introduction and analysis of the Quality Shielded contact box KYN61 Manufacturers china introduces the characteristics of insulating materials, hope it helps you.
