Description:
HIVOLT silicone rubber long rod insulators deserve your trust. firstly high quality come from high level raw materials and parts :
1 the metail fittings all come from forged steel material instead of cast steel .
there are no air , inpurity material in side , the whole metal fittings are completely free of defect . as result of this , the final insualtors will be in high level and reliable during working life .
all metal fittings are hot - dip galvanized , zinc coating thickness Min. 85um , it can change based on customer's requirement up to 127um.
2 insulator sheath & shed are made of silicone rubber , the supplier is Dow Corning.
3 silicone rubber insulator core are made of reinforced fiber glass .
Applications:
Suitable for tension string or suspension string in transmission lines 220KV , corona ring available based on different customer's requirement.
Competitive Advantage:
we offer 3 years quality guarantee period after shipment .
The silicone rubber sheds have a very good self-cleaning character . it is easy for maintenance .
the big / small sheds profile can provide high electrical performance , make insulator
more suitable for heavy pollution area.
We can design insulators based on customer’s requirement or special technical specifications.
