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.
IEC60273 has many requirement for high voltage IEC Ceramic station post insulator C10-1425, C12.5-1425, such as the dimensional requirement, test and inspection requirement, tolerance requirement, and so on, it also has detailed parameters for all of IEC standard station post insulator On IEC60273.
Except high voltage IEC Ceramic station post insulator C10-1425,C12.5-1425, C4-1425, C6-1050, C8-1050, C16-1050, C20-1050 are in the same types. Main parameter is as follows:
Cantilever strength: 4KN, 6KN, 8KN, 10KN, 12.5KN, 16KN, 20KN
Lightning impulse withstand voltage: 1425KV
Switch impulse withstand voltage wet: 950
Height of insulator: 3150mm
Creepage distance: 5600mm, 7800mm
