The theory behind PROTECTA*LITE® systems is state of the art. It consists of a special metaloxide surge arrester in parallel with line insulation.

During a surge, the metal-oxide arrester limits the voltage across the insulation to a value below the insulator flashover voltage. Therefore, the lightning surge current is diverted to ground in a controlled manner and the insulation is left intact. The system works for direct lightning strokes to phase conductors and for backflash attributed to poor grounding and capacitive coupling.

PROTECTA*LITE systems utilize, only the highest quality Metal-Oxide Varistors (MOV) combined with durable, time proven polymer housings.

Since 1988, PROTECTA*LITE systems have reduced interruptions at system voltages from 2.4 to 400 kV. Higher voltage PROTECTA*LITE systems are available.

PROTECTA*LITE systems are available as an assemblies of polymer insulators and arresters, or as an arrester alone. Construction with a PROTECTA*LITE assembly brings with it many advantages and configurations.
