HIVOLT line post insulators choose high quality materials for parts
1 top clamp frame and bottom base use high density ductile iron or
malleable iron ,every pieces test qualified after magnetic powder
inspection . the top clamps made of high density cast aluminum
alloy which are suitable for bare AAAC or ACSR conductors.
all metal fittings are hot dip galvanized , zinc thickness Min.
2 Porcelain the insulation part use high aluminum porcelain C130 ,
It depends on different mechanical requirement . the porcelain
surface covered a layer of hard and shinning glaze ,
3 the metal fittings and porcelain are bonded with portland cement
, the finish product have very good mechanical performance and the
quality more reliable . our customers are very satisfied with the
Suitable for transmission lines up to 55KV etc. The insulator can
be used as horizontal position or vertical position , the insulator
base are gain base or flat base ,it depends on how to use the
insulators. it is suitable for wooden pole or round poles or cross
the top clamp are universal type , it can be used for AAAC , AAC ,
ACSR conductors etc.
the high quality porcelian insulators can work more than 50 years
on line under proper maintenance .
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 .
