Wialan has successfully designed a hermetically sealed electrical box for Mexico’s Comision Federal de Electricidad (CFE) in response to a request from our Mexican partner DESARROLLO GLOBAL EN TELECOMUNICACIONES DGT S.A. DE C.V (DGT). The box features an aluminum base that connects the isolators and holds the grounding copper bar. Our smaller box includes four ports for grounding up to four transformers, while the larger box has eight ports for grounding up to seven devices using the copper bar.
