Insulator Washing

Hot Line Insulator Washing – Hot Line Washing is basically a procedure where insulators on electrical lines are cleaned with water while the electricity is energized (on).  If the insulators are not cleaned, a flashover may occur causing brownouts, blackouts and damaged equipment. The Waterous CPT-4 pump is an ideal solution for hot line insulator washing. With pressures up to 800 PSI (55 bar), the insulators can be cleaned while power is still supplied to customers.
