Logistics and network
Shipping to Laos.
Consignments for Laos move Sea from Nhava Sheva to Laem Chabang (Thailand), then road via Nong Khai to Vientiane; or via Da Nang (Vietnam) for the south. Typical transit is 12 to 18 days to port, 3 to 6 days road; discharge at Laem Chabang (Thailand) or Da Nang (Vietnam), then road. We quote Ex Factory or FOB Nhava Sheva; CIF Laem Chabang on request, with payment by LC at sight or advance, USD.
The grid runs at 50 Hz with 400/230 V low-voltage supply and 22 kV distribution as the national standard, with 35 kV in some provinces and 12.7 kV single-wire rural lines; 115 kV transmission. Distribution is operated by Electricite du Laos (EDL) and EDL-Transmission, regulated by Ministry of Energy and Mines. Import conformity: EDL technical specifications and type-test certificates; IEC standards.
Distribution transformers are the highest-volume line on the campus — around 900 jobs a month across the full IS 1180 rating ladder, from 16 kVA agricultural units to 1000 kVA industrial supply.
Standard build is Dyn11, ONAN, 11/0.433 kV or 33/0.433 kV, with off-circuit tapping. But almost nothing here is fixed: vector group, impedance, tapping range, winding material, fittings and efficiency level are all specified by the purchaser, and we build to that schedule rather than asking you to accept ours.
