Porcelain insulators for transmission play an important role in isolating and supporting power lines and transmission towers. There is a lack of research on porcelain insulators for transmission compared to other power installations. Therefore, in this paper, the measurement and analysis of insulation strength and cement corrosion of porcelain insulators for power transmission were carried out. Domestic pollution level calculation is determined by the equivalent salt deposit density (ESDD). In this paper, insulation strength measurement and cement corrosion analysis were performed by extracting 36,000lbs porcelain insulators from 427.3m, 469.9m and 571m away from the coast. As a result, the average insulation strength of porcelain insulators, 427.3m away from the coast, was measured as 29,400MΩ. The insulation strength of porcelain insulators 571m away from the coast was measured at 2,500MΩ. The measurement results show a 11.8-fold decrease in the insulation strength in porcelain insulators that are relatively far from the coast and closer to the mountainous region than the insulation strength of porcelain insulators near the coast. As a result of cement corrosion measurement of the sample, hydrogen ion concentration(pH) was measured to estimate degradation. Cement corrosion of porcelain insulators that are extracted from the research was measured at pH 13 of porcelain insulators, 427.3m from the coast. The pH of porcelain insulators at 469.9m away was measured at 11, and the pH of porcelain insulators 571m away from the coast and close to the mountainous area was measured at 7. Stress accumulation of cement with humidity is considered to be more important factors for reducing the insulation strength of porcelain insulators to determine cement corrosion than salt in coastal areas.
