We produce long rod silicone rubber insulators with high pressure injection shapping method .

The insulators have excellent both mechanical & electrical performance .  The silicone rubber we used are HTV type (high temperature vulcanization).

The both end metal fittings material are made of forged steel , Fiber glass rod material is ECR FRP type .  All those materials can guarantee the final product in high quality .

1)We offer high quality dead end composite insulators and long rod insulators according to ANSI standard and IEC standards .

2) The shed color 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 independent Labs.  The high quality will make you very 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 fitting’s 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 of HTV silicone rubber . The rubber component are specially designed by ourselves . It can provide high level electrical & mechanical performance .

C  Insulator core are made of reinforced ERC FRP high density fiber glass .

D The connection metal fittings can be designed as ball &  socket  , Tongue & Clevis , or Y & Ball etc. according to IEC standards.

E  Single insulator will be package in carton drum .

F  The insulator shaping method is high pressure injection .

The long rod insulators are suitable for tension string or suspension string in transmission lines or substations.  Corona rings will be used together with long rod insulators if necessary . The corona ring can even electrical field , and increase flashover voltage , protect transmission lines.

Good Advantage of HIVOLT insulators :

W 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 profile , 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.
