The 138kV silicone rubber stay insulator have below performance:
1 end metals are made of forged steel , which are uniform ,without any inner defect .of course the related cost are higher than cast steel , but the performance are more reliable .it will be free of air ,sand, inpruity things.
the metal fitting are hot-dip galavanized , zinc thickness meet related IEC and ASTM 153 standard .
2 the fiber glass core covered a layer of silicone rubber sheath . normally such product will use UV proof painting instead of silicone rubber sheath . of course it is cheaper and easy handling , but the product electrical performance low down much . and painting is easy removeable .
so our design are more reliable.
the silicone rubber stay insulator can be used as stay insulators at the distribution line end , and also it can used as live line spacer .
Advanced design can offer longer working life, and save end user 's cost .
we offer 2 years quality insurance time after shipment .that is becuase we are full of confidence for our
product . offering better service is our goal always.
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.
