POWERSIL® silicones are high-end silicone elastomers that range from low-viscosity to ready-to-use solid rubbers. They are used to produce long-rod insulators/surge arresters and hollow insulators as well as to coat insulators, especially glass and ceramic insulators.

Benefits:

  • Good mechanical properties
  • Excellent dielectric properties
  • Ready to use
  • Two-part system
  • Extremely low-viscosity liquid rubber
  • Excellent processing in appropriate mixing and metering systems
  • High tracking and erosion resistance

Benefits of POWERSIL® in long-rod insulators:

  • Long service life due to excellent hydrophobic properties and resistance to heat, UV and ozone
  • Easy to use due to low weight
  • Excellent toughness and impact strength due to flexibility
  • High flashover resistance due to hydrophobic surface
  • Low maintenance costs due to hydrophobicity transfer

Benefits of POWERSIL® in hollow insulators:

  • Excellent process safety and flexibility due to low-pressure molding process
  • Easy handling due to low weight (80 % lighter than porcelain insulators)
  • Excellent toughness and impact strength due to flexibility
  • High flashover resistance due to hydrophobic surface

Benefits of POWERSIL® as insulator coating:

  • High operational reliability due to excellent hydrophobic properties
  • Cost efficiency due to scope for retrofitting existing installations
  • Extended service life due to silicone coating (10 years and longer)
