Insulator washing

Postby Heli_Al » Thu Jun 22 2017, 22:10

Hi Team

Quick question .... who has had experience (recently) with cleaning insulators on powerlines cause I'd like to know if high pressure cleaning is necessary or is there a cleaning product that can be applied with low pressure ... so not using the water blaster technique if you get my drift ??

Like that cleaning product tv advert in NZ "spray and walk away"

Cheers

Ask the guys at either Aeropower or Meridian Helicopters. Both those specialise in insulator washing.

The water blasting technique uses demineralised water which means that the water is not conductive. This is the only method that is used (& approved by power companies) both by helicopter or ground based means (i.e. bucket trucks) on any LIVE power line. Use any other solution on an insulator that has several thousand volts running past it will contain enough particles in the liquid to complete an electrical circuit (conductive) which will result in a nice big flash of light & A LOT of %!$$#@ off people without power.
