ESP insulators

ESP insulators is one of porcelain insulators used for transmission and distribution power lines, which is divided into low-voltage insulators, medium-voltage insulators and high-voltage insulators.

ESP insulators

The types of ESP insulators have
◆ Conical support insulator
◆ Cylindrical support insulator
◆ Support insulator, used in substations and power plant
◆ Pin type insulator: used on distribution overhead power lines
◆ Suspension insulator: used for distribution and transmission power lines
◆ Bus cut insulator: also called standoff insulators
◆ FRP rod insulator: as known as silicon guy strain insulator
◆ Shaft insulator for ESP: end fittings cemented on porcelain
◆ Wall through bushing: usually used with conductors

High voltage support insulators are ESP insulators that 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.

Cylindrical support insulator is one of popular ESP insulators also called split cylindrical insulators to positively seal penetrations associated with older double post support designs and can be used precipitator subsystems
