Logistics and network
Shipping to Rwanda.
Consignments for Rwanda move Sea to Dar es Salaam, then road on the Central Corridor to Kigali, about 1,400 km; or via Mombasa on the Northern Corridor. Typical transit is 12 to 16 days to port, 7 to 10 days road; discharge at Dar es Salaam or Mombasa, then road. We quote Ex Factory or FOB Mundra / Nhava Sheva; CIF Dar es Salaam on request, with payment by LC at sight or advance, USD.
The grid runs at 50 Hz with 400/230 V low-voltage supply and 30 kV distribution as the national standard, with 15 kV in Kigali and Rwamagana; 110 kV and 220 kV transmission. Distribution is operated by Rwanda Energy Group: Energy Utility Corporation (EUCL) and Energy Development Corporation (EDCL), regulated by Rwanda Utilities Regulatory Authority (RURA). Import conformity: Rwanda Standards Board (RSB) import conformity and REG reticulation standards; IEC designs.
The power transformer line closed the last gap in the chain. Between distribution and power class we now cover 16 kVA right through to 20 MVA — a span very few regional manufacturers hold on a single site.
The standard substation build is 33/11 kV, Dyn11, ONAN, with an off-circuit tap changer at +5% to −10%. Where the network needs voltage regulation under load we fit an on-load tap changer at +5% to −15%, and where the load profile justifies forced cooling we supply ONAF with a rated output at each cooling stage.
