Logistics and network
Shipping to Kenya.
Consignments for Kenya move Sea from Mundra or Nhava Sheva to Mombasa, then road or rail (SGR) to Nairobi. Typical transit is 10 to 14 days; discharge at Mombasa. We quote Ex Factory or FOB Mundra / Nhava Sheva; CIF Mombasa on request, 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; 66 kV and 132 kV sub-transmission. Distribution is operated by Kenya Power (KPLC) and KETRACO for transmission, regulated by Energy and Petroleum Regulatory Authority (EPRA). Import conformity: KEBS Pre-Export Verification of Conformity (PVoC): Certificate of Conformity before shipment (Route A, B or C); destination inspection at Mombasa otherwise.
The product
A solar transformer is not a distribution transformer with a different label.
An inverter feeds the transformer a non-sinusoidal current with significant harmonic content, and it does so on a duty cycle that is de-energised for roughly half the year. Both facts change the design.
Harmonic currents drive eddy-current heating in the windings that a standard design does not allow for, so conductors are transposed and the core flux density is de-rated to leave headroom. The overnight de-energised period means no-load loss dominates lifetime energy cost far more than it does on a distribution feeder — which is why the low-no-load-loss design is worth paying for here and not always elsewhere.

Specifying
What changes for Kenya.
- Climate and site: Coastal humid at Mombasa; Nairobi and the highlands at 1,500 to 2,100 m, altitude derating applies.
- Built to IEC 60076 for 50 Hz, with insulation levels for the 11 kV and 33 kV distribution 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 (Kenya Power (KPLC) and KETRACO for transmission); 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 Kenya requires one.
