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.
A servo stabilizer holds the output voltage steady by continuously varying a motorised variac, rather than switching between fixed taps. That gives smooth correction with no waveform distortion and no switching transient — which matters when the load is a CNC machine, a medical imaging system or a process line rather than a lighting circuit.
Three-phase units are built as single-variac (all phases corrected together) or three-variac (each phase independently). Specify three-variac where the incoming supply is unbalanced, as most Indian industrial feeders are.

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.
