Logistics and network
Shipping to Guinea.
Consignments for Guinea move Sea from Nhava Sheva to Conakry, then road. Typical transit is 28 to 40 days; discharge at Conakry. We quote Ex Factory or FOB Mundra / Nhava Sheva, with payment by LC at sight or advance, USD or EUR.
The grid runs at 50 Hz with 400/230 V low-voltage supply and Medium-voltage distribution to IEC practice (20 kV and 30 kV classes); 110 kV and 225 kV transmission. Distribution is operated by Electricite de Guinee (EDG), regulated by Ministry of Energy; AREE regulator. Import conformity: EDG technical specifications; IEC designs; French-language documentation.
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.
