1000kV 300kN Composite Long Rod Insulator / Polymer Station Post Insulators For EHV Lines

1000kV 300kN composite long rod insulator ball & socket type IEC61109 standard for EHV lines

Specifications:

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.
