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 voltage frames.

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. Insulators can also be furnished with the surfaces glazed, or non-glazed, depending on the application or customer preference.

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, typically following process design changes that result in changes of operating pressures. These process design changes may adversely affect precipitator subsystems such as the insulator compartment pressurization system.
