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
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
4 the 500kV silicone rubber lond rod insulator are ball & eye
connection according to IEC standard.
5 single insulator will be package with 1 carton drum .
Suitable for tension string or suspension string in transmission
lines 500KV . 2 pcs corona rings will be offered together with long
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
the fiber glass core material is ECR FRP rod , it is special used
for high voltage product instead of normal type.
