?
ANSI 55-4 pin type porcelain insulators are designed according to ANSI C29.5.
?the product used for low voltage or medium voltage distributions lines.
?insulator can be grey or brown against different specifications.
?normally those products will be with porcelain thread , lead head pins are recommended for use with those insulators . the cantilever strength test shall also be conducted with lead head pins .
the pin type insulator top are with semi-conductive glaze.
the insulator thread hole also covered with semi-conductive glaze . the semi-conductitive glaze can even electric field , and decrease the electricity affect for telegraph .
?we can provide lead head pins for insulator assembly based on customer& acute;s requirement.
?
Applications:
The 55-4 pin type porcelain insulator is used for low voltage or medium voltage distributions lines. These insulators are commonly installed vertically on metal or wooden structures based to support the
conductor .
?
Competitive Advantage:
The HIVOLT pin type insulator 55-4 are made of high strength?porcelain , which have excellent mechanical and electrical performance.
before delivery , we will conduct routine tested? and sample test on insulators?,
?in this case ,?we? can guarantee?our product?are well controlled.
we offer 3 years quality guarantee .
the product price are very competitive .
