IEC ceramic station post insulator C6-850,C8-850,C10-850
IEC ceramic station post insulator C6-850, C8-850, C10-850 for high voltage made by Orient Power China is used on HV substation. The station post insulator is normally circular column type and assembled with end fittings at the both ends of the high voltage insulator. The holes on the end fittings should be co-axial, and enables the perfect assembly in the future on the substations.
The end fittings of IEC ceramic station post insulator C6-850, C8-850, C10-850 for high voltage use should be hot dip galvanized. After galvanizing, the porcelain station post insulator can be antirust, and have better lifespan when use. Normally the end fittings of IEC ceramic station post insulator C6-850, C8-850, C10-850 is cast iron. After casting, it will be tapped to make some thread according to IEC or BS standard.
IEC ceramic station post insulator C6-850, C8-850, C10-850
The main parameters of IEC ceramic station post insulator C6-850, C8-850, C10-850:
Cantilever strength: 4KN, 6KN, 8KN, 10KN, 12.5KN, 16KN, 20KN
Lightning impulse withstand voltage: 850KV
Power frequency withstand voltage wet: 360KV
Height of insulator: 1900mm
Creepage distance: 3100mm, 4400mm
Fixing diameter of end fitting hole: 127, 225, 254 ,275 or 300mm
C4-850, C12.5-850, C16-850 and C20-850 has the same parameters above, but different cantilever strength.
IEC ceramic station post insulator C6-850, C8-850, C10-850 end fittings fixing holes should equally spread, on the same circle of the end fitting in order to be easily assembled when use on the substation, Every piece is important on quality, and the inspection and test before delivery is very important. Orient Power makes tests on each batch of IEC ceramic station post insulator C6-850, C8-850, C10-850 for high voltage use.
We can also supply good quality ANSI 55-3 pin type insulator according to ANSI C29.5 or customer's drawings. Maybe you are interested in this type insulator.
