Umzimba wokumelana wenziwe nge-stable resistance alloy. I-elementi yeribhoni ilinyazwe onqenqemeni ngendlela ye-helix, bese iphothwa kubakaki be-ceramic. Izinga lokushisa eliqhubekayo langaphezulu aweqi ku-375ºC. Uchungechunge lwe-REWR-G lungasetshenziselwa noma yiluphi uhlelo lokusebenza lwamandla e-AC noma e-DC. Amayunithi ajwayeleke kakhulu ku-VFD braking, control motor, load banks kanye ne neutral grounding nokunye. Usayizi womkhiqizo kanye nenani kungaklanywa ngokuya ngezidingo zekhasimende, noma kuhlanganiswe kube izingxenye.
