1.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
2.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 in heavy polluted area
