Logistics and network
Shipping to Sri Lanka.
Consignments for Sri Lanka move Sea from Nhava Sheva or Mundra to Colombo, then road. Typical transit is 4 to 7 days; discharge at Colombo. 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 400/230 V low-voltage supply and 11 kV and 33 kV distribution; 132 kV and 220 kV transmission. Distribution is operated by Ceylon Electricity Board (CEB) and Lanka Electricity Company (LECO), regulated by Public Utilities Commission of Sri Lanka (PUCSL). Import conformity: SLSI consignment-based import inspection scheme for regulated products including cables and conductors; CEB and LECO technical specifications and type approvals.
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.
