Cleaning in case of heavy pollution
Thanks to the hydrophobicity of the silicone housing, normal pollution does not af-
fect the insulation capacity of the housing. If pollution exceeding this is present
(heavy deposit layer) the surge arrester should be cleaned.
Solvents and abrasive equipment
Damage to the silicone housing.
Do not use cleaning agents containing solvents besides isopropanol
CAUTION
Do not use abrasive equipment for cleaning.
Do not use silicone grease or silicone oil after the cleaning.
