Description:
1000kV silicone rubber long rod insulators with mechanical strength 300kN which have below characters :
1 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 .
2 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 .
3 insulator core are made of reinforced ERC FRP high density fiber glass .
4 the 500kV silicone rubber lond rod insulator are ball & socket connection according to IEC standard.
5 single insulator will be package with 1 carton drum .
6 the insulator shaping method is high pressure injection .
Applications:
the long rod insulator 1000kV 300kN are suitable for tension string or suspension string in EHV transmission lines . 2 pcs corona rings will be used together with long rod insulators , and assembled on both end of insulators , it can even electrical field . increase flashover voltage , protect transmission lines.
Competitive Advantage:
we offer 2 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.
