Description:
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.
85um.
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
quality .
Applications:
Suitable for transmission lines up to 46KV etc. The insulator can
be used as horizontal position specially , 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:
the high quality porcelian insulators can work more than 30 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 .
