IEC Ceramic station post insulator C10-1425, C12.5-1425 made by BONLE INSULATORS in China is on good quality and under severe test. Station post insulator which is applied on high voltage substations need high quality since it is big and Each IEC Ceramic station post insulator C10-1425, C12.5-1425 should have done strict test under standard confirm its good quality.
IEC Ceramic station post insulator C10-1425, C12.5-1425 end fittings for high voltage use should be hot dip galvanized. After galvanizing, the station post insulator can be antirust, and have can be used for a long time. Normally the end fittings of IEC ceramic solid core insulator C10-1425, C12.5-1425 is cast iron type like other fitting assembled for line insulators. After casting, it will be tapped to make some thread in order to assemble with other parts.
