6 Maintenance
6.1 Recommended maintenance
General
The bushings are maintenance free, no regular maintenance is necessary.
DANGER!
Risk of electrocution!
Do not go near the bushing while it is energized, or ungrounded. High voltages can kill you.
Make sure that the bushing is de-energized, and grounded before you do work on it.
Cleaning of the insulator surface
If the insulator is exposed to very high pollution, it can be necessary to clean the surface. Remove the
pollution with a moist cloth, or a low pressure water jet. If necessary, put isopropyl alcohol on the cloth.
DANGER!
1,1,1 -Trichloroethane or Methyl-chloride are not recommended as detergents, because they are
dangerous to persons and the environment.
CAUTION!
Do not wash the insulators with a high pressure water jet. This can cause damage to the joints in
the insulator, and between the insulator and metal parts.
