Description:
500kV silicone rubber long rod insulators with mechanical strength 300kN which have below advanced 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
2 insulator sheath & 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 & eye connection according to IEC standard.
Applications:
Suitable for tension string or suspension string in transmission lines 500KV . 2 pcs corona rings will be offered together with long rod insulators
Competitive Advantage:
High reliable mechanical & electrical performance , we offer 2 years up to 5 years quality guarantee .
The insulator have a very good self-cleaning performance . it is easy for maintenance .
The insulator specially designed for heavy pollution zone.
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.
