The long rod stay insulator have below characters:
1 metal fittings are made of forged steel , without any inner defect . the cost are a little bit higher than cast steel , but it can provide much reliable performance .
the metal fitting zinc coating are Min. 86um , meet related IEC and ASTM standard .
2 the fiber glass core covered a layer of silicone rubber shealth . normally such product will use UV proof painting instead of silicone rubber . of course it can save some cost , but the product electrical performance low down much . and painting is easy removeable .
so our design will provide better service condition.
the long rod stay insulator can be used as stay insulators at the distribution line end , and also it can used as spacer for transmission lines.
Advanced design will offer longer working life , and save the utilities ' cost .
we offer 2 years up to 5 years quality insurance time .
forged steel metal fittings will never lead to failure due to material defect .
the fiber glass core material is ECR FRP rod , it is special used for high voltage product instead of normal type.
