Orient Power adopts high temperature vulcanized silicone rubber for
best long-term performance to ensure the highest possible
durability of sheds, as well as outstanding tracking and erosion
resistance. Using only hard-wearing HTV silicone rubber also
ensures superior performance in sandstorm areas and minimization of
damage during transportation and handling.
Over 220KV composite insulators must adopt injection for making
silicone rubber housing to protect FRP core. Both of these
composite insulator ends with grading ring. Such as 110kVcomposite suspension insulatorusually has one grading ring on the end, The end fittings assembly
way (pressure) is crimp to increase mechanical strength.
