Types of suspension insulator strings


  1. Single suspension insulator string.

  2. Double suspension insulator string for one conductor/twin conductors.

  3. Triple suspension insulator string.

  4. Jumper insulator string.

  5. V insulator string.


Arcing horn or Corona ring for High voltage strings


  The suspension insulator strings are protected by arcing horns of galvanized steel, on the live and earthed sides. The size and shape of the horns are selected such as 

  1) To assume that the arcs will ignite between the horns

  2) To minimize the reduction of the lightning impulse, withstand the voltage of the strings.
