Product OVerview

The purpose of our TVSS is to ensure that your oilfield equipment keeps producing longer when lighting strikes. The energy of a pulse surge from lightning or switching is limited to the specified voltage of our device using Metal Oxide Varistors, (MOV’s). The MOV’s absorb the energy and dissipate it as heat into the air for our 480 V equipment and into specially engineered epoxy that remains pliable to allow expansion and contraction without cracking for all of our high voltage models.
