Polymer arrester solution for high mechanical strength applications
In special cases with very high demands for mechanical strength, the moulded design may not provide the optimal solution (particularly at system voltages above 420 kV). Instead, what is required is a mix between the features of the standard EXLIM and the moulded PEXLIM designs.
The HS (High Strength) PEXLIM tube design provides this by offering comparable mechanical strength to EXLIM arresters, but with much less mass. The seismic and pollution performance is in line with the moulded PEXLIM arresters and thus superior to conventional porcelain designs.
