ANSI 56-5 pin type porcelain insulators are designed according to
ANSI C29.6.
the product normally used for high voltage distributions lines.
Glaze color can be grey or brown according to different customer
requirement.
the insulator assembled will be with zinc thimble thread .
the pin type insulator top are with semi-conductive glaze, it is radio-free type.
after insulator design , we will conduct design tests on
insulators , the test items shown below:
1: Low frequency dry flashover test
2: Low frequency dry flashover test
3: Critical impulse flashover test ( Positive and Negative )
4: Radio influence voltage test
5: Thermal shock test
Routine test : flashover test
Applications:
The ANSI 56-5 pin type porcelain insulator is used for high voltage distributions lines up to 69kV.
Steel head pins will be used for such big and heavy porcelain
insulators .
Now a days , less and less customer use such heavy insulators ,
they prefer to replace them with
silicone rubber insulators . because it is more lighter and easy
handle and maintenance .
Competitive Advantage:
The HIVOLT pin type insulator ANSI 56-5 are made of high aluminum
porcelain C-130 , 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 .
Competitive price will help end user save their cost .
