ANSI standard pin type insulator technical performance listed below :
| ||Technical Specification||Unit||Value|
|2||Max. Shed Diameter||mm||350|
|5||Low Frequency Puncture Voltage||KV||225|
35kV pin type insulators are designed according to BS standard .the
product are very popular in UK ,
and many African countries . there is a zinc thimble insert inside
the insulators , which can accept
BS standard large steel head spindles . the spindle dimensions
comply to BS 3288 standard .
we can produce the insulator in brown glaze or grey glaze .
insulator top groove area can be made of semi-conductive glaze
which is radio-free type ,
or normal type (without semi-conductive glaze)
when we finished production , we will conduct routine test and
samples test based on BS standard.
test items including :
1 visual inspection and dimensional check
2 temperature cycle test
3 cantilever strength test
4 porosity test
5 puncture test
only in case the batch of product passed related test , we will
pack and deliver the insulators out .
The 36kV BS standard pin type insulator is used for high voltage distributions lines as insulation parts.
this kind of product with very high creepage distance , so it can
be used in heavy pollution area .
of course , if customer required suitable spindle for insulator
assembly , we will offer accordingly .
we choose high class raw materials for production , such as clay ,
feldspar , silicate etc.
during production , we contol production procedure very strictly .
we know high quality final products depends on every qualified
if customer have interests on our proudct , we will offer samples
for evaluation free of charge .
because we are full of confidence on it .
hope we can set up long term cooperation relationship.
