U120BP Fog Type Porcelain Insulator
120kn Anti-Fog Disc Type Porcelain/Ceramic Insulator Disc Suspension Porcelain Insulator U120BP/146HU120BP/146H is a universal model used by IEC, corresponding to models from Chinese manufacturers such as LXHP4-120, LXHP-120, FC120P/146, etc.This type of insulator is widely used in overhead transmission lines, especially suitable for coastal areas, heavy industrial areas, areas with severe air pollution or high humidity such as foggy and dusty areas, as well as high altitude and high voltage level lines. When selecting, it is necessary to determine the required creepage distance and umbrella skirt structure based on the pollution level of the specific line
