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)

Design principle of a cold-shrinkable joint

Cable accessories made with POWERSIL® silicone rubber are used in high and low voltage cables. They allow for various types of field control – from high to low voltage, as well as for both push-on and cold-shrink technologies.

Benefits:

  • Outstanding dielectric properties
  • Permanent elasticity over a broad temperature range
  • Excellent hydrophobic properties and resistance to heat, UV and ozone
  • Very good tracking resistance
  • High arcing resistance

Production method:

  • Solid silicone rubber (HTV)
  • Liquid silicone rubber (LSR)
  • Extra-low-viscosity systems (POWERSIL® XLR®)
  • Room-temperature-curing systems (RTV-2)

POWERSIL® Fluids are low-viscosity silicone fluids that have been specifically optimized for the insulating systems employed in modern transformers. POWERSIL® Fluids are used here for cooling and insulating as well as for high-voltage terminations.

Benefits:

  • High heat resistance
  • Short-term thermal shock resistance
  • Very high, long-term heat resistance
  • Use at low temperatures with rated output
  • Extremely low dissipation factor
  • Minimal change in electrical properties over a wide temperature range
