Linkage arresters offer all the advantages of a metal oxide distribution arrester in a lightweight, compact polymeric housing designed for both indoor and outdoor overhead applications. Compared to porcelain arresters, polymer housings resist vibration, mechanical shock, climate-related stress, and seismic impact—greatly reducing breakage risk.
These arresters also exhibit excellent transient overvoltage (TOV) behavior and superior surge protection characteristics, ensuring reliable performance in distribution networks. In the event of severe internal arc failure, porcelain housings typically explode, while polymer housings split open safely to relieve pressure.
The built-in ground lead disconnector automatically separates the arrester from the system under overcurrent conditions and provides a clear visual indication of arrester failure. Each unit includes a 22 mm² soft-stranded copper grounding lead for secure installation.
