Our insulators are exposed daily to enormous tensile stress in the construction of transmission lines, because the towers used in energy transmission utilize 1300 ft to 1700 ft spans with a weight of approx. 22 tons. They must remain exposed to these forces for a duration of several decades without endangering safety or reduction in their functionality.

Environmental influences, such as

  • rain
  • storm
  • tempest

  • sunlight
  • heat
  • drought

 

as well as extreme climatic conditions around the world also place a challenge on materials and products.
