Composite vertical line post insulator with spindle performance:
Excellent electrical characteristic, high mechanical strength and extension intensity of fiberglass epoxy resin lead-out rod have 2 times stronger than general steel, 10 times higher than porcelain. So it's more safe and reliable.
Good resistance to soiling and flashover, not required to be cleaned by hand. Flashover voltage is 1.6-2 times higher than the same creepage of porcelain insulator. It is very useful for composite insulators in heavy polluted area.
Small volume, light weight (only 1/6-1/19 of the porcelain with the same voltage level) and flexible structure are convenient for transportation and installation.

Composite vertical line post insulator with spindle is often used in steel structures whose geometry varies from line to line. A combined loading test to reproduce the loading cases in such structures is in the scope of this standard and it would be very easy to specify a general test which covers the majority of geometry and loading cases.

The common types of Composite vertical line post insulator with spindle are 51-1c, 51-2c, 51-3c, 51-4c, 51-1F, 51-2F, 51-3F, 51-4F, 51-11, 51-12, 51-13, 51-14, 51-15 and 51-16. Other composite insulator line post type also can be made as per customers’ requirements.
