What is a Polymer Insulator?

Polymer Insulator Definition

The Polymer Insulator consists of two parts, one is a glass fiber reinforced epoxy resin rod-like core, and the other is a windproof canopy made of silicone rubber.

Polymer Insulator Advantages

• Very lightweight

• As the composite insulator is flexible the chance of breakage becomes minimum.

• Lighter in weigh

• Smaller in size

• Performance is better

Polymer Insulator Disadvantages

• Moisture may enter in the core if there is any unwanted gap between core and weather sheds. This may cause the electrical failure of the insulator.

  
  

• Over crimping in end fittings may result in cracks in the core which leads to mechanical failure of polymer insulator.
