The composite post insulator in aging

by:Mings     2020-05-18

composite post insulator is often applied to the power of our electric power industry equipment, the use of it for our electrical work has brought the very big help, and pollution resistance, corrosion resistance, anti-aging, no deformation, no fading, the characteristics of the following is by our staff to do detailed introduction for you. Electric power equipment for the work of our electricity has brought the very big help, composite post insulator is a very good power equipment, its use is very extensive, but in a perfect product also has its shortcomings, it is in use after a long period of time will appear the cause of aging, aging is the leading cause of pillar composite insulation fault, because of the damp mist or dew cause uneven voltage, led to the creeping discharge. In the night by image enhancement instrument observation of the transmission line, under the condition of damp, actual creeping discharge can occur in each line. After a long run, ultraviolet ray and cause degradation creeping discharge, etc. At the beginning of the degradation is accompanied by surface discoloration, appear opaque and crack. These changes increase the surface roughness, leading to impurity accumulation rate rise. The corona discharge and surface may produce corrosion, an umbrella group of cracking or piercings. Therefore, composite post insulator after running for a long time, will not be able to guarantee its service life. So we in the use of a period of time will need to check it found problems in a timely manner to replace, so can guarantee it bring more help for our electrical work. If you have questions, you can call our hotline contact like us.
