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 product
A solar transformer is not a distribution transformer with a different label.
An inverter feeds the transformer a non-sinusoidal current with significant harmonic content, and it does so on a duty cycle that is de-energised for roughly half the year. Both facts change the design.
Harmonic currents drive eddy-current heating in the windings that a standard design does not allow for, so conductors are transposed and the core flux density is de-rated to leave headroom. The overnight de-energised period means no-load loss dominates lifetime energy cost far more than it does on a distribution feeder — which is why the low-no-load-loss design is worth paying for here and not always elsewhere.

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.
