12‑24 kV SF6‑insulated floor‑standing ring‑main‑unit, DMS‑system compatible, IAC‑AFL internal‑arc rated, tropical‑climate suitable, 50 Hz, for MEA utility underground distribution‑network projects.
This is MEA official utility procurement specification for SF6‑insulated ring‑main‑unit, targeting EPC contractors, tenderers and design‑institutes for tender response and pre‑award evaluation.
It complies with prevailing IEC switchgear standards, defines mechanical construction, safety interlock requirements, two transformer‑feeder protection schemes, DMS‑FRTU auxiliary‑system configuration, outdoor kiosk specifications, strict witness‑type‑test requirements, warehouse lot‑sampling acceptance rules and complete tender‑phase document deliverables for high‑humidity tropical urban operating environment.
Project‑oriented adaptation and FAT are supported. Contact us for compliance‑check templates and full qualification documents.
G3 maintenance-free ring main unit (RMU) for 33kV, 35kV, 40.5kV, offering eco-efficient, compact, and reliable medium-voltage distribution.
Medium voltage SF6 gas insulated ring main unit for 24kV, offering compact, reliable, and maintenance-free power distribution.
24kV SF6 insulated RMU/ring main unit: compact, reliable switchgear for power distribution. High safety, low maintenance—ideal for urban & industrial grids.
Outdoor kiosk defines minimum steel‑plate thickness, anti‑corrosion painting standard, rain‑removable roof, IP protection rating, lifting & foundation‑mounting structure and bi‑lingual warning‑plate requirements. Please contact us for outdoor‑enclosure‑spec‑guidance.
It supports DIN‑standard HRC fuse‑switch solution with fuse‑triggered opening‑mechanism, or auxiliary‑power‑free protective‑relay for circuit‑breaker bays; both shall satisfy defined protection‑logic and interlock constraints. Please contact us for protection‑scheme‑selection guidance.
Internal‑arc test shall be performed by listed internationally‑recognized high‑voltage test‑laboratories or STL‑member institutes; test shall cover both switch gas‑compartment and incoming cable‑compartment. Please contact us for test‑laboratory reference‑list.
