As horizontal line post insulator, ANSI 57-23 porcelain line post insulator is mainly exposed to pressure, bending and torsional forces during operation and have been specifically designed for this purpose.
Orient is also happy to offer our customers a customized full-service solution tailored ideally to their requirements. The economical design for our ANSI 57-23 porcelain line post insulator lasts far longer in the field. With many in operation for the last 25 years, these horizontal line post insulator products exhibit no change in their mechanical/electrical characteristics, proving to be highly reliable in the field. Our porcelain line post insulators are approved by the RUS.
