ESP Insulators
High Voltage Support Insulators
High voltage support insulators mechanically support and electrically isolate the discharge electrodes from the grounded ESP casing and collecting curtains. Support insulators are designed for high compressive strength to support the loads imposed by the high voltage electrodes and associated high...
Discharge Electrode Rapper Shaft Insulators
As dust accumulates on the discharge electrodes of an electrostatic precipitator, the clearance between the discharge electrodes and the grounded collecting electrodes will diminish. Rappers are used to clean of the discharge electrodes to maintain clearances.
The rapping energy is transmitted to...
Lower Alignment (Anti-Sway) Insulators
When deemed appropriate, lower alignment insulators - or "anti-sway" or "stabilizer" insulators as they are more commonly known - are provided on each high voltage guide frame to maintain the stability and the alignment of the lower extremity of each high voltage section. Lower...
Wall Bushings / Feed Through Bushings Insulators
It is inevitable that a high voltage bus (pipe or cable) must at some point pass from the clean environment of a bus duct to the dirty environment of the precipitator interior. Similarly, a high voltage bus may be required to transit between a low-pressure environment to a high-pressure environment...
Post/Stand Off Insulators
One of the most overlooked insulators on a precipitator is the stand off insulator. Stand off insulators provide points of support in long bus runs to maintain adequate clearances between the high voltage bus and grounded precipitator components. Stand off insulators are found in bus ducts to...
