Composite Polymeric Insulators (11-132 kV)

Ranking among the top manufacturers of composite polymer insulators, Compaq International is a popular online portal, which manufactures medium and high voltage composite polymer 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

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

• Line Post insulators • Station post insulators • Suspension & Tension insulators
