Logistics and network
Shipping to United Arab Emirates.
Consignments for United Arab Emirates move Sea from Mundra or Nhava Sheva to Jebel Ali, then road to any emirate. Typical transit is 3 to 5 days; discharge at Jebel Ali (Dubai), Khalifa Port (Abu Dhabi). We quote Ex Factory or FOB Mundra / Nhava Sheva, with payment by LC at sight or advance, USD or AED.
The grid runs at 50 Hz with 400/230 V low-voltage supply and 11 kV and 33 kV distribution (22 kV in parts of Abu Dhabi); 132 kV and above transmission. Distribution is operated by DEWA (Dubai), ADDC and TRANSCO (Abu Dhabi), SEWA (Sharjah), EtihadWE (northern emirates), regulated by Emirate-level regulators and the Ministry of Energy and Infrastructure. Import conformity: ESMA / MoIAT ECAS applies to low-voltage equipment up to 1,000 V; medium-voltage equipment is accepted against utility specifications and type-test certificates (DEWA, ADDC, SEWA).
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.
