Polymer insulators are a special insulated control product, and can play an important role in the overhead transmission lines.

Polymer insulators advantages and properties:
Special shed profiles for all contamination categories
Good hydrophobic performance, Good antipollution performance, High density material, High electrical strength
Acid resistant core rod; End fittings Galvanized; Double sealing silicone housing
Modular system with slide-on assembly
Suitable for the middle and above contamination areas, particularly in the heavy contamination areas
Manufactured according to IEC61109, 62217 and IEC 60120

Polymer insulators types can be classified into composite transmission and distribution line insulator and composite station post insulator according to the position of use.
