We developed silicone rubber pin type insulators which equivalent
to porcelain units .
the silicone rubber types have good proformance , it save much unit
weight , and easy for handling .
normally the insulators can work more than 20 years on line .
the insulator has tipe top or clamp top , which suitable for accept
bare conductors .
the insulator pin can be long or short type , which suitable for
wooden crossarm or steel crossarm .
the pin insulator core material is fiberglass rod which produced
from the highest quality materials. Strands are aligned for maximum
cantilever strength. The rod is more than 50 percent glass fibers
in cross section.
End fittings are cast steel.the fittings surface are hot dip
galvanized , or aluminum alloy .
which provide same mechanical performance.
the silicone rubber are HTV type ,which come from Dow Corning .
Interface between silicone rubber and fiberglass rod are well
treated with sealant .
This feature prevents intrusion of moisture and contaminating
elements.
Applications:
The 15 kV silicone rubber pin type insulators are used on
distrbution lines . These insulators are commonly installed
vertically on metal cross arm to support the conductor .
Competitive Advantage:
. The pin type insulator has excellent mechanical and electrical
performance.
• Eliminate or Reduce Maintenance and is compatible with existing
plant
• Safety (light weight for handling and installation)
• Long service Life (consistent performance over its service life)
