we sell huge quantity of ANSI 52-5 disc insulators to North
Americans and South American countries due to good quality and very
competitive price .
now HIVOLT already become to a very reputable brand in those areas.
we manufacture the insulators with C-120 porcelain material, so the insulators have very good mechanical & electrical
character . after production , we will test each insulator with
below routine test :
1 tension load test with applied mechanical strength 60kN withstand
for 1 minute
2 flashover test , to sort the unqualified product out . if the
insulator punctured , that means the insulators are unqualified .
we must sort them 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.
Applications:
ANSI 52-5 class insulators can be used for tension string or
suspension string from 110kV up to 330kV electrical power lines .
Competitive Advantage:
ANSI 52-5 normal type insulators are very reliable .
the failure rate is lower than 1.1 per 100000 .
quality guarantee period is Min. 1 years after shipment.
we use special component of glaze , so the porcelain surface have
very good self-cleaning character . it makes maintenance more
convenient .
We can produce the insulator with different colors : grey , brown ,
white or green .
