Logistics and network
Shipping to Nigeria.
Consignments for Nigeria move Sea from Nhava Sheva or Mundra to Lagos (Apapa or Tin Can Island), then road. Typical transit is 25 to 35 days; discharge at Lagos: Apapa / Tin Can Island; Onne for the Niger Delta. 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 415/240 V low-voltage supply and 11 kV and 33 kV distribution (grid code nominal levels 330, 132, 66, 33 and 11 kV). Distribution is operated by Transmission Company of Nigeria (TCN) and the eleven DisCos (Ikeja, Eko, Abuja, Kano, Port Harcourt and others), regulated by Nigerian Electricity Regulatory Commission (NERC); NEMSA for installation safety. Import conformity: SONCAP: a Product Certificate (PC) and a SONCAP Certificate (SC) issued by a SON-appointed agency before shipment, presented at the port; transformers are a stated SON testing focus.
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 Nigeria.
- Climate and site: Hot humid coast (Lagos, Port Harcourt) with heavy corrosion exposure; dry Sahel north (Kano) with dust and 45 °C ambient.
- Built to IEC 60076 for 50 Hz, with insulation levels for the 11 kV and 33 kV distribution (grid code nominal levels 330, 132, 66, 33 and 11 kV) and 415/240 V secondaries; temperature-rise limits and cooling sized for the stated ambient and altitude.
- Fittings, bushings and tap-changer ranges follow the utility specification (Transmission Company of Nigeria (TCN) and the eleven DisCos (Ikeja, Eko, Abuja, Kano, Port Harcourt and others)); 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 Nigeria requires one.
