Logistics and network
Shipping to Tanzania.
Consignments for Tanzania move Sea from Mundra or Nhava Sheva to Dar es Salaam, then road inland. Typical transit is 12 to 16 days; discharge at Dar es Salaam. 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 11 kV and 33 kV distribution; 132 kV, 220 kV and 400 kV transmission. Distribution is operated by Tanzania Electric Supply Company (TANESCO), regulated by Energy and Water Utilities Regulatory Authority (EWURA). Import conformity: TBS Pre-Export Verification of Conformity (PVoC): consignment-based Certificate of Conformity valid three months, issued by Intertek, SGS or TUV Rheinland under the 2025-2028 contract.
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 Tanzania.
- Climate and site: Humid coast at Dar es Salaam; dry plateau inland at 1,000 to 1,500 m (Dodoma, Arusha, Mbeya).
- Built to IEC 60076 for 50 Hz, with insulation levels for the 11 kV and 33 kV distribution and 400/230 V secondaries; temperature-rise limits and cooling sized for the stated ambient and altitude.
- Fittings, bushings and tap-changer ranges follow the utility specification (Tanzania Electric Supply Company (TANESCO)); 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 Tanzania requires one.
