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.
The power transformer line closed the last gap in the chain. Between distribution and power class we now cover 16 kVA right through to 20 MVA — a span very few regional manufacturers hold on a single site.
The standard substation build is 33/11 kV, Dyn11, ONAN, with an off-circuit tap changer at +5% to −10%. Where the network needs voltage regulation under load we fit an on-load tap changer at +5% to −15%, and where the load profile justifies forced cooling we supply ONAF with a rated output at each cooling stage.
