Muhtasari wa Kiufundi
Advanced Ring Main Units & Underground Cable Distribution
Ring Main Units (RMUs) and Gas-Insulated Switchgear (GIS) provide compact, climate-independent medium-voltage switching and circuit protection. Encapsulated in hermetically sealed 304 stainless steel gas tanks or solid epoxy resin, they operate reliably in harsh, humid, or flood-prone environments.
Our range includes SF6-insulated RMUs (XH-RMU-12), SF6-free solid-insulated green RMUs (XH-SRMU-12), and outdoor cable branch tap boxes (XH-CBB-12) with integrated load switches and circuit breaker modules.
