• Provides a grounding disconnect with a strain relief system

• For use on towers with verticle or horizontal conductor configurations

• Eliminates the need to increase standard insulation level for conventional system upgrades

KEY FEATURES TE Connectivity’s (TE) Transmission Line Arresters (TLA) reduce the number of non-scheduled outages and improve system reliability by protecting the transmission line from damaging voltage transients.

Benefits• Minimizing circuit breaker operation with possible system outage

resulting from back flashover on the transmission line.

• Switching overvoltages are absorbed over the length of the line thus reducing the severity of surges at the substation.

• Transmission systems can be operated even where sub-soil gives poor tower footing resistance.

• Minimizes voltage outages for sensitive industrial processes.

• Installation of Transmission Line Arresters on a standard 3 phase voltage system at calculated intervals, provides voltage support for the transmission system.
