We produce long rod silicone rubber insulator with high pressure rubber injection shapping mehtod .
the insulator have excellent both mechanical & electrical performance . the silicone rubber we use are HTV type (high temperature vulcanization).
the both end metal fittings material are forged steel . fiber glass rod material is ECR FRP type . all those material guarantee our product in high quality level .
1) we offer high quality dead end composite insulators and long rod insulators according to ANSI standard and IEC standard .
2) the shed colour can be light gray or red .
3) The long rod insulators can be made up to 1000 kV 500kN . and the related goods type tested in independant Lab. the high quality will make you satisfied .
HIVOLT long rod silicone rubber insulators have below characters :
A The metal fittings use high density forged steel , every piece of fitting are tested by magnetic power test .to guarantee each unit fittings have uniform structure and perfect performance
The fittings surface are hot-dip galvanized meet related international standard requirement
zinc thickness are more than 85um. according to IEC standard and ASTM153 .
B Long rod insulator shed are made with material of high temperautre silicone rubber . the rubber component are specially designed by ourself . it can provide high level both electrical & mechanical performance .
C insulator core are made of reinforced ERC FRP high density fiber glass .
D the silicone rubber lond rod insulator are ball & socket connection according to IEC standard.
E single insulator will be package with 1 carton drum .
F the insulator shaping method is high pressure injection .
the long rod insulator are suitable for tension string or suspension string in transmission lines . corona rings will be used together with long rod insulators if necessary . the corona ring can even electrical field . increase flashover voltage , protect transmission lines.
Good Advantage of HIVOLT insulators :
we offer 3 years quality guarantee period , good quality deserve your trust !
The insulator have a very good self-cleaning performance . it is easy for maintenance .
The insulator has big / small sheds profilr , which specially designed for heavy pollution zone or coastal area .
We can design insulators based on customer’s requirement or special technical specifications.
the fiber glass core material is ECR FRP rod , it is special used for high voltage product instead of normal type.
