U100 Double Shell Two Winged Glass Insulator with specifications 146, 280, 450 refers to a high voltage glass insulator characterized by:

Socket coupling diameter: 146 mm
Overall diameter: 280 mm

Creepage distance: 450 mm

ThiThis type of powerline insulator is typically used in powerline applications and is designed to resist pollution and fog effects, enhancing its insulation performance under adverse environmental conditions. The "Double Shed" or "Double Shell" design increases the creepage distance, which helps prevent electrical leakage and flashover. The "Two Winged" description likely refers to the shape or configuration of the sheds (the protruding rings) on the insulator that increase surface distance for electrical insulation.

Are there any specific applications for the U100b series electrical insulators?

  • U100b series electric insulators are specifically applied in high-voltage overhead power line systems, particularly for mechanical support and electrical insulation of conductors. Their typical applications include:
  • Use in power transmission and distribution lines where mechanical load capacity around 100 kN is required.
  • Installation as suspension or tension insulators in bare conductor lines to provide insulation and mechanical strength.
  • Suitable for polluted or high-contamination environments due to their design features such as double shell or double shed shapes that increase creepage distance and reduce leakage currents.
  • Often used in bird protection systems and dead-end strings in medium voltage networks (e.g., 15-66 kV), where they help maintain phase-earth safety distances and reduce electrocution risks.
  • Compatible with polymeric silicone coatings or covers to enhance hydrophobicity, UV resistance, and performance in saline or harsh weather conditions, extending service life beyond 20 years.
  • Employed in structural solutions for 2nd and 3rd category networks where bird perching deterrents and insulated surfaces are required to meet environmental and safety regulations.
