we sell huge quantity of ANSI 52-8 suspension insulators to North
Americans and South American countries due to good quality and very
competetive price .
now HIVOLT has become to a very famous brand in those countries .
we use porcelain material C-130 producing this type of product , so
the insulator will have very good mechanical charactor . after
production , we will test each insulator with below routine test :
1 tension load test with applied mechanical strength 80kN withstand
for 1 minute
2 flashover test , to sort the unqualified product out .
after routine test , we will also do sample test on each batch to
be sure the related batch of product are qualified . test items
including : dimensions check , thermal shock test ,zinc thickness
test on metal fittings , combined electrical & mechanical test
, puncture test etc.
ANSI 52-8 are very suitable for tension string in electrical lines
from 110kV up to 500kV electrical lines .
ANSI 52-8 insulators are very reliable .
the failure rate is lower than 1.2 per 100000 .
product quality insurance period is Min. 1 years after BL date .
we use special component of glaze , so the porcelain surface have
very good self-cleaning character . it makes maintenance more
We can produce the insulator with different colors : grey , brown ,
white or green .
