Logistics and network
Shipping to Ethiopia.
Consignments for Ethiopia move Sea to Djibouti (Doraleh), then road to Addis Ababa, about 900 km. Typical transit is 8 to 12 days to Djibouti, 3 to 5 days road; discharge at Djibouti (Doraleh), then road. We quote Ex Factory or FOB Mundra / Nhava Sheva; CIF Djibouti on request, with payment by LC at sight or advance, USD.
The grid runs at 50 Hz with 380/220 V low-voltage supply and 15 kV and 33 kV distribution (EEU reports over 54,000 km of 15/33 kV lines); 132 kV, 230 kV and 400 kV transmission. Distribution is operated by Ethiopian Electric Utility (EEU) for distribution and Ethiopian Electric Power (EEP) for generation and transmission, regulated by Ethiopian Petroleum and Energy Authority. Import conformity: ECAE Pre-Export Verification of Conformity: Certificate of Conformity valid six months, issued by an ECAE-authorised body; local inspection and testing for uncertified consignments.
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.

Specifying
What changes for Ethiopia.
- Climate and site: Addis Ababa and the highlands at 2,000 to 2,500 m, altitude derating of insulation and cooling; hot lowlands at Dire Dawa.
- Built to IEC 60076 for 50 Hz, with insulation levels for the 15 kV and 33 kV distribution (EEU reports over 54,000 km of 15/33 kV lines) and 380/220 V secondaries; temperature-rise limits and cooling sized for the stated ambient and altitude.
- Fittings, bushings and tap-changer ranges follow the utility specification (Ethiopian Electric Utility (EEU) for distribution and Ethiopian Electric Power (EEP) for generation and transmission); type-test certificates from CPRI or ERDA accompany the offer.
- Documentation: commercial invoice, packing list, certificate of origin, test certificates and the import conformity certificate where Ethiopia requires one.
