Pin Type Polymeric Insulator:
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
3.Small volumn,light weight,(only 1/6-1/19 of the porcelain with the same voltage level )flexible structure,convenient for transportation and installation.
4.Silicone rubber housing has great hydrophobic property to protect against inside wet,not require the monitor of preventation and clean,reduce daily maintenance.
5.Good sealing performance,strength anti-electrical erosion,the tolerance leakage degree reaches TMA 4.5 degree.They have excellent resistance against erosion,low temperature and can be applicable for ambient temperature from -40 degrees to +50degrees.
