Logistics and network
Shipping to Nepal.
Consignments for Nepal move By road from Haryana through the Sunauli or Raxaul-Birgunj border, about 1,100 to 1,300 km, 4 to 6 days door to door; sea-land via Kolkata or Visakhapatnam for containerised cargo. Typical transit is road: 4 to 6 days; sea via Kolkata: 10 to 14 days; discharge at Birgunj dry port (Sirsiya ICD) or direct road delivery. We quote Ex Factory, FOB Kolkata or delivered-at-border on request, with payment by LC at sight or advance, INR or USD.
The grid runs at 50 Hz with 400/230 V low-voltage supply and 11 kV and 33 kV distribution with 33/11 kV substations; 66 kV and 132 kV sub-transmission. Distribution is operated by Nepal Electricity Authority (NEA), regulated by Electricity Regulatory Commission (ERC). Import conformity: NEA technical specifications and type-test certificates; Nepal Bureau of Standards and Metrology (NBSM) for marked products.
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.

Specifying
What changes for Nepal.
- Climate and site: Terai plains to 45 °C; hill and mountain districts with altitude derating above 1,000 m and cold starts.
- Built to IEC 60076 for 50 Hz, with insulation levels for the 11 kV and 33 kV distribution with 33/11 kV substations and 400/230 V secondaries; temperature-rise limits and cooling sized for the stated ambient and altitude.
- Fittings, bushings and tap-changer ranges follow the utility specification (Nepal Electricity Authority (NEA)); 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 Nepal requires one.
