Nigeria Market Focus
Factory-Direct Oil-Immersed Distribution Supply
XinHuan is a China-based power transformer manufacturer exporting directly from our Hefei facility to Nigeria via Lagos (Apapa/Tin Can Island), Port Harcourt, and Onne deep-water ports. We engineer 50Hz oil-immersed distribution transformers and cast-resin dry-type units specifically compliant with Nigerian Electricity Management Services Agency (NEMSA) technical standards, Standards Organisation of Nigeria (SONCAP) certification guidelines, and local Distribution Companies (DisCos including Eko, Ikeja, IBEDC, AEDC, and EEDC) grid requirements.
We supply 50kVA to 3150kVA distribution units across Nigeria's standard 11kV and 33kV primary distribution networks with 415V/240V (3-phase 4-wire) secondary output. Engineered for Nigeria's humid tropical environment, our transformers feature heavy-duty IP54/IP55 weather-sealed corrugated tanks, high-temperature rise margins, Dyn11 vector groups, and copper or aluminum windings designed for industrial plants, estate substations, mini-grid electrification, and oil & gas facilities in Lagos, Ogun, Port Harcourt, and Kano.

Local Market Notes
What Buyers Usually Care About in Nigeria
Nigeria enquiries often start with the incoming feeder voltage, LV output, and whether the project is for a mini-grid, estate, factory, utility, or oil and gas distribution package.
Buyers usually want clear accessory scope early, especially arrester, fuse, cable box, metering, CT/PT, and protection-panel coordination for site delivery and local approval.
Port planning matters up front because Lagos/Apapa, Onne, or Port Harcourt routing can affect packing method, inland trucking, and delivery timing.
Procurement Notes
Information That Speeds Up Approval
Prepare the single-line diagram, required HV/LV ratio, vector group, and site installation condition before requesting the final quote.
If utility review is involved, note the nameplate requirements, loss expectation, tap range, and any preferred accessory brand or layout.
Tell us whether you need skid base, wooden crate, or container loading guidance for inland delivery after port arrival.
