Description:
HIVOLT line post insulators are made of high quality materials :
1 top clamp frame and bottom base use high density ductile iron ,every piece of metal fittings are tested before assembly with porcelain parts . the top clamps made of high density aluminum alloy which are suitable for bare AAAC or ACSR conductors.
all ductile iron metal fittings are hot dip galvanized , zinc thickness Min. 85um.
2 Porcelain are made of high aluminum porcelain C130 ,the porcelain surface covered a layer of hard and shinning glaze , brown ,grey colour available depends on customer's requirement.
3 the metal fittings and porcelain are bonded with portland cement , the finish product have very good mechanical performance and the quality more reliable .
Applications:
Suitable for transmission lines up to 35KV etc. The insulator can be used as horizontal position , the insulator base are gain base . it is suitable for wooden pole or round poles .
the top clamp are universal type , it can be used for AAAC , AAC , ACSR conductors etc.
Competitive Advantage:
we offer 3 years up to 5 years quality guarantee for our product .
The insulator finish are smooth and shinning , it has very good self-cleaning performance and easy for maintenance .
OEM design are available .
