ANSI 56-2 pin type porcelain insulators are designed according to ANSI C29.6.
the product used for high voltage distributions lines.
insulator can be grey or brown against different specifications.
normally those products will be with zinc thimble thread or porcelain thread , steel head or lead head spindles are all suitable for use with those insulators .
the pin type insulator top are with semi-conductive glaze, it is radio-free type.
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's requirement.
below sample test items will be conducted before delivery on each batch of insulators:
1: Visual and dimensional test
2: Porosity test
3: Cantilever strength test
4: Pinhole gaging test
5: Puncture test
Applications:
The ANSI 56-2 pin type porcelain insulator is used for high voltage distributions lines.
normally the pin type insulators will be used together with lead head or steel head spindles .
Metal or wooden cross arm all applicable .
Competitive Advantage:
The HIVOLT pin type insulator ANSI 56-2 are made of high strength porcelain C-120 , which have excellent mechanical and electrical performance. we have advanced our design to decrease the unit weight , which is more suitable for transportation or live line assembly .
before delivery , we will conduct routine tested and sample test on insulators ,
in this case , we can guarantee our product are in reliable quality .
we offer 3 years quality guarantee .
OEM product avaiable for customers.
