Product Description
IEC Standard Semi-Conductive Porcelain Power Line Insulators
OEM customization available for all insulator models
Product Overview
Porcelain power line insulators are critical components used between transformer rectifiers and discharge electrode suspensions in electrostatic precipitators (ESP). These insulators function as both insulating and supporting elements for bus rods, effectively leading high voltage into the electric field. Available in two structural types: pure ceramic insulators and combined insulators.
