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 framing. Providing the primary application point for high voltage and located in close proximity to the gas stream, high voltage support insulator design must also consider the voltage applied and operating environment.
Hamon Research-Cottrell can supply your requirements for standard cylindrical support insulators, double post insulators and "bigfoot" support insulators (i.e. conically shaped insulator with a wide base for use with extremely high voltage, wide collector plate spacing, applications). Insulators are available in porcelain and various grades of alumina, based on application requirements.
In addition to our standard line of support insulators, Hamon Research-Cottrell can also supply split cylindrical insulators to positively seal penetrations associated with older double post support designs. The split insulator is an ideal solution when positive sealing is needed following process design changes that result in changes of operating pressure that adversely affect precipitator subsystems such as the insulator compartment ventilation system.
