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.
Distribution transformers are the highest-volume line on the campus — around 900 jobs a month across the full IS 1180 rating ladder, from 16 kVA agricultural units to 1000 kVA industrial supply.
Standard build is Dyn11, ONAN, 11/0.433 kV or 33/0.433 kV, with off-circuit tapping. But almost nothing here is fixed: vector group, impedance, tapping range, winding material, fittings and efficiency level are all specified by the purchaser, and we build to that schedule rather than asking you to accept ours.
