Overview
Polymer post insulator is used in dirty areas, high mechanical tensile loads, large spans and compact lines. The flashover voltage is 30%-50% higher than the same grade porcelain and glass insulators. Stable performance at -60 degrees - +200 degrees ambient temperature; non-breakdown design, no need to measure zero value during operation.
Good bending resistance performance, strong anti-fouling ability and impact resistance, vibration and anti-brittle fracture performance, small volume, light weight, convenient installation, free maintenance.
