Introduction:

Composite / Polymer insulators are used to give support to the
overhead line conductors on the poles to prevent the current
flow towards earth.
Used to insulate the utility poles and transmission towers
which are used to attach electric power distribution lines or
Transmission lines.
Support the weight of the suspended wires without allowing
the current to flow through the tower to the ground.

Advantages of Composite / Polymer Insulators Over Porcelain Insulators
  • Hydrophobic in nature, exhibits excellent pollution performance.
  • Lightweight, flame retardant, and shatter-resistant.
  • High resistance to flashovers and punctures.
  • Excellent tracking and erosion resistance.
  • Aerodynamic design offers maximum resistance.
  • High power arc resistance due to high thermal withstand ability.
  • Low leakage current and power loss due to its high surface resistivity.
  • Superior handling of mechanical shock loads.
  • Easy to handle, transport, and erect.
  • Can easily replace existing porcelain insulators without affecting pole/tower structure.
