Tyco Electronics’ Transmission Line Arresters (TLA) reduce the number of non-scheduled outages and improve system reliability by protecting the transimission line from damaging voltage transients.

Features• HV arrester suspended from a transmission line giving enhanced transmission line performance.• Increasing system line voltage on standard insulated transmission line.• Provides an earthing disconnect with a strain relief system.

Benefits• Minimizing circuit breaker operation with possible system outage resulting from back flashover on the transmis- sion line.• Switching overvoltages are absorbed over the length of the line reducing the severity of surge 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.• Eliminates the need to increase standard insulation level for conventional system upgrades.

ApplicationsTransmission Line Surge Arrester up •

to 230 kV.Utilized on towers with either vertical •

or horizontal conductor configurations.
