<p>The circular rim, which has the dielectric properties is attached to the insulator in a manner so that the wire which is under voltage is held approximately in the centre of the circular rim. The highest point of the circular rim bears a small plate with spikes preventing the birds from landing on what is in fact the highest point of the circular rim. The circular rim will also prevent the birds from getting into the dangerously close vicinity from the high voltage wire through stepping on the console supporting the insulators.</p> |
