Product Description

The Advantages of Polymer Surge Arresters

Polymer surge arrester construction offers tangible benefits over traditional porcelain designs.

SAFETY

Polymer surge arresters are superior over porcelain with regards to improved safety under failure and fire-retardancy. Unlike porcelain, the polymer housing will not shatter or scatter pieces when damaged and they are lighter making for easier, safer installation.

DURABILITY

High impact resistance of polymer housing significantly reduces housing damage losses typically associated with porcelain housing during transport and installation at site.

COMPACT

The compact design of polymer housing arresters allows for flexibility in installation space and ease of handling during installation.

Field of application

For protection of transformers, switchgear and transmission lines against atmospheric and switching over-voltages. Selection of arresters has to be carried out according to IEC 60099-4/2004 and ANSI/IEEE C62.11/2005.
