The Fenarro DFW-12 Outdoor Ring Main Unit (RMU) is a cornerstone of modern, reliable 10kV cable distribution networks. Utilizing SF6 gas for insulation and arc-quenching, it provides a fully sealed, maintenance-free solution that is impervious to dust, moisture, and atmospheric contamination. Its compact, modular design allows for a variety of feeder and switching schemes, making it perfect for both loop and radial network configurations. The unit is “future-proof,” with built-in provisions for easy integration of Distribution Terminal Units (DTU), fault indicators, and communication modules, enabling swift transition to smart grid automation.
Maintenance-Free Operation: Hermetically sealed stainless steel tanks filled with SF6 gas eliminate internal condensation and corrosion.
Compact & Lightweight: Significantly smaller than air-insulated alternatives, saving valuable space.
High Safety: Live parts are completely enclosed, ensuring operator safety and public protection.
Automation Ready: Pre-equipped with voltage transformers and spaces for RTU/DTU mounting.
Durability: Powder-coated exterior withstands UV radiation and harsh environmental conditions (C4/C5 corrosion resistance).
