Logistics and network
Shipping to Zambia.
Consignments for Zambia move Sea to Dar es Salaam, then road on the TAZARA corridor to Lusaka, about 1,900 km; or via Beira or Durban. Typical transit is 12 to 18 days to port, 7 to 12 days road; discharge at Dar es Salaam, Beira or Durban, then road. We quote Ex Factory or FOB Mundra / Nhava Sheva, 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; 66 kV, 88 kV, 132 kV and 330 kV transmission. Distribution is operated by ZESCO; Copperbelt Energy Corporation (CEC) on the Copperbelt, regulated by Energy Regulation Board (ERB). Import conformity: Zambia Compulsory Standards Agency (ZCSA) compulsory standards for electrical products and ZABS marks (ZS 688 for cables); pre-shipment verification where applicable.
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 Zambia.
- Climate and site: Plateau at 1,000 to 1,400 m, 35 °C dry season; altitude derating applies.
- 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 (ZESCO; Copperbelt Energy Corporation (CEC) on the Copperbelt); 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 Zambia requires one.
