Composite Polymeric Insulators (11-132 kV)

Ranking among the top manufacturers of composite polymer insulators, Compaq International is a popular company, which manufactures medium and high voltage composite polymer insulators like Composite silicone insulators , Polymer line Post Insulators.  The insulators we design include pin type composite insulators, suspension long rod silicone rubber insulators, station post polymer insulators, cross arm silicone rubber insulators, Polymer disc insulator, electrified railway polymer insulators and etc.

Product descriptions

Our Polymer Insulators are manufactured to cater to application requirements even for severe environments. They come with a polymeric housing over, which is a pultruded fiber glass rod. An aluminum end fittings or galvanized steel are attached to this glass rod. Based on customers’ needs and application requirements, Compaq International also provides them with housing materials in silicone or ethylene vinyl acetate (EVA)

Salient Features of our Plymeric Insulators

  • Lower leakage current
  • High mechanical strength
  • No need of zero value check
  • Highly resistance to breakage
  • Suitable for polluted environments
  • Excellent hydrophobic performance
  • Perfect solution  for high polluted area
  • 70-80% lighter than porcelain insulators
  • Free of economical maintenance & cleaning
  • Easy and economical for transportation and installation
  • Not brittle, and reduce the purchasing quantities for spare parts
