IEC Standard Electrical Porcelain Insulators , 27KV Pin Post
HIVOLT line post insulators choose high quality materials for parts
1 Metal Caps the cap use high density ductile iron or malleable
iron ,every pieces test qualified after magnetic powder inspection
. the top clamps made of high density cast aluminum alloy which are
suitable for conductor size 0.25” to 2.7” ..
Both cap and assembly bolt are hot galvanized , zinc thickness meet
related IEC and ASTM standard requirement
2 Porcelain the insulation part use high aluminum porcelain C120 or
C130 , It depends on different mechanical requirement . the
porcelain surface covered a layer of hard and shinning glaze ,
color can be grey , brown or white .
3 Cement excellent Portland cement make the assembled insulator
have very good mechanical performance and the quality more reliable
Suitable for transmission lines up to 138KV etc. The insulator can
be used as vertical or horizontal , the insulator top can be
porcelain tie top or with aluminum clamps .
We use high aluminum porcelain , in this case , the insulator core
diameter are smaller ,while the mechanical strength are in high
level . compare with other supplier’s product , we decrease much
the unit weight . it is more suitable for insulator assembly in
lines , and make easier maintenance.
we offer 3 years up to 5 years quality guarantee . high quality
deserve your trust !
The porcelain glaze are smooth and shinning , have a very good
self-cleaning performance . it is easy for maintenance .
We can design insulators based on customer’s requirement or special
