An insulator pressure washer is a mechanical high-pressure washer designed to remove contamination/pollution from overhead power line insulators with the power on (energized) using low conductivity water. Cleaning is necessary to prevent flashovers (high-voltage shorts to earth across the insulators), which can damage power line equipment.
The basic design consists of the following components:
Power Source (a diesel engine or a power take-off from a truck chassis)
centrifugal water pump
stainless steel water storage tank
high-pressure water hose
high-pressure dead-man type water wash gun
Electrical grounds for the wash gun and washing system
Insulator washers typically have a pump pressure of about 1000 psi and a nozzle pressure between 500 and 750 psi. They have a very high flow rate (about 60 gallons per minute), necessary to provide consistent and fast cleaning.
Insulator washers have several basic design layouts as follows:
Trailer mount for use in electricity substations
Chassis mount for mounting on a truck bed
Aerial platform mount for mounting on trucks that have aerial platforms
Helicopter mounted units
The washer must be able to access the towers to be washed. If the towers are off road in rough terrain, a 4x4, 6x4 or 6x6 truck chassis may be required.
The systems must have a robust design as they are used outdoors, often in adverse climates.
