Polymer Post Insulator

Composite post insulators are used in outdoor substations, power distribution devices and electrical equipment.


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.
