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 .
Applications:
Suitable for distribution lines up to 24KV . The insulator can be used as vertical position, the insulator top is assembled with aluminum clamps to hold and support conductors.
Competitive Advantage:
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 technical specifications.
