Composite suspension insulator is used in overhead transmission line or distribution line. And the voltage can be AC or DC. Our voltage range for composite long rod insulator is from 10kV to 800kV. Our 500kV composite suspension insulator is one step injection and has gotten the patent. This composite insulator can be used in tension tower to assembly tension string to tensile conductor or used in suspension tower to assembly suspension string to suspend conductor.
Insulator fiberglass rod is produced from the highest quality materials. Strands are aligned for maximum tensile 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 .
Zinc coating comply to IEC and ANSI such international standards .
Weathersheds are high pressure injection molded . Housings manufactured with silicone rubber , high mechanical strength, high corona resistance and low permeability to moisture.
Interface between silicone rubber and fiberglass rod are well treated.
This feature prevents intrusion of moisture and contaminating elements.
Many colors for selection, Red color, Grey color or Customer’s specifications
. The finish product have excellent mechanical and electrical performance.
• Eliminate or Reduce Maintenance and is compatible with existing plant
• Improves Power Quality (lower RI and TVI)
• Safety (light weight for handling and installation)
• Service Life (consistent performance over its service life)
