Actually, the insulating material cannot always keep its property, it can be effected by a lot of other factors. Such as environment, operating condition and so on. These important factors can affect the insulation aging and reduce the using time for insulation material. The following is a brief introduction.
The concept of insulation aging
In the course of electrical equipment operation due to long-term by various factors, the insulation material occurs a series of irreversible chemical and physical changes, resulting in electrical and mechanical properties of the deterioration, this irreversible change is often referred to as aging. Insulation aging is divided into heat aging, environmental aging and electrical aging. Factors that cause aging are heat, electricity, light, oxygen, radiation and microbes.
Due to the heat, the aging of the insulating material is called heat aging. In the heat aging process, the polymer insulation material often occurs thermal degradation, low molecular weight generation or escape. So that the insulation properties of insulating materials and mechanical properties decreased.
In electrical equipment, the insulating material in the role of the electric field, the performance of irreversible changes until the failure, the process known as electrical aging. The main reason for the aging of insulating materials is partial discharge. As the partial discharge of ozone, ozone is a strong oxidant, so that the double bond with the macromolecules from the reaction, the material ozone cracking.
Aging of the environment
Environmental aging refers to the insulating material in the light, oxygen, radiation and acid and other factors caused by the pollution of chemical reactions, in which the sun is the main factor in ultraviolet light.
But the insulation material from ZTELEC GROUP can help you to reduce worrying about insulation aging. Because all of base material we used are best and it can protect your motor or transformer in many ways.
