Description:
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.
Applications:
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.
Competitive Advantage:
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.
