Abstract: 

SOME CONSIDERATION IS NECESSARY FOR PRODUCING OR PERFORMANCE AN INSULATORS:
1) MATERIAL PROPERTIES
2) HIGH PERFORMANCE IN CONTAMINATED AREA.
3) COST
CERAMIC INSULATORS, ESPECIALLY PORCELAINS AND GLASSES STILL ARE ECONOMIC AND SUITABLE TYPES OF INSULATORS IN DIFFERENT CLIMATIC CONDITIONS IN IRAN. THESE INSULATORS ARE WIDELY USED IN TRANSMISSION AND DISTRIBUTION LINES. THERE ARE SEVERAL REPORTS ABOUT FAILURES OF THE INSULATORS IN HUMID AND CONTAMINATED AREAS. AN EFFECTIVE TECHNIQUE FOR IMPROVING OF THE PERFORMANCE OF INSULATORS IS: APPLYING RTV SILICON RUBBER ON INSULATOR SURFACE AS A PERIODIC MAINTENANCE. RTV COATINGS NOW HAVE MORE THAN EXPERIENCE AND DEVELOPMENT IN HIGH VOLTAGE LINES. IN MOST CONTAMINATED REGIONS, THE COATINGS MAY BE RESIST FOR A PERIOD OF 10 YEARS, WITHOUT ADDITIONAL MAINTENANCE SERVICES. IF THE PERIODIC WASHING BE NECESSARY FOR THE COATINGS, THE PERIOD IS CONSIDERABLY LONGER. THE RESULTS SHOW THAT THE PRESENCE OF RTV COATING CAN BE TEND TO IMPROVE FLASH-OVER VOLTAGE, IMPROVE IN HYDROPHOBICITY PROPERTY, AND PREVENT OF LEAKAGE CURRENT. APPLYING THE COATING ON PORCELAIN OR GLASS INSULATORS IS A BEST SOLUTION IN CONTAMINATION PROBLEM.
