IEC porcelain station post insulator C6-750,C8-750,C10-750
IEC porcelain station post insulator C6-750, C8-750, C10-750 made in China by Orient Power is on hot sale. Post insulator requires high quality since it is big and is applied on high voltage substations. Each IEC porcelain station post insulator C6-750, C8-750, C10-750 should be under severe inspection and test and confirm the good quality of each type.
The height of IEC porcelain station post insulator C6-750, C8-750, C10-750 is 1700, and the tolerance of it is ±2.5, it is the same tolerance as C6-650, but bigger than other small insulators, other small insulators such as C6-550, C4-250, C4-325, C6-450, the tolerance of them is ±1, IEC60273 has detailed requirement for the tolerance of the porcelain station post insulator C6-750, C8-750, C10-750.

The fixing holes of the station post insulator should equally planned on the ending fitting, they should be on the same circle of the end fitting of porcelain station post insulator C6-750, C8-750, C10-750. If not, the assembly will be hard when use on the substation, and since the assembly of the end fitting on the high voltage insulator can’t be detatched from the it, the insulator will be unqualified. It will be a big lost since the value of porcelain station post insulator C6-750, C8-750, C10-750 is costly.
Some parameters of IEC porcelain station post insulator C6-750, C8-750, C10-750, C2-750, C4-750, C12.5-750, C16-750, C20-750:
Cantilever strength: 2KN, 4KN, 6KN, 8KN, 10KN, 12.5KN, 16KN, 20KN
