we sell big quantity of ANSI 52-3 disc insulators to USA , and many South American countries and Caribbeans .because our product have very good performances .
For example :
1 the insulator mechanical strength are more than 30% higher than rated value .
2 the insulator surface covered a layer of hard shinning glaze . it will lead to good self-cleaning performance , it is also very easy for cleaning by line man .
Applications:
insulator 52-3 are very suitable for tension string or suspension string in electrical lines from 11kV up to 132kV. in some substations , you can also find it .
Competitive Advantage:
HIVOLT 52-3 insulators have a very reliable electrical & machincal character .
the failure rate is lower than 1 per 100000 .
We can design insulators based on customer’s requirement or special technical specifications.
