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.
A servo stabilizer holds the output voltage steady by continuously varying a motorised variac, rather than switching between fixed taps. That gives smooth correction with no waveform distortion and no switching transient — which matters when the load is a CNC machine, a medical imaging system or a process line rather than a lighting circuit.
Three-phase units are built as single-variac (all phases corrected together) or three-variac (each phase independently). Specify three-variac where the incoming supply is unbalanced, as most Indian industrial feeders are.

Specifying
What changes for Sri Lanka.
- Climate and site: Coastal humid, 35 °C with salt-laden air; hill country above 1,000 m.
- Built to IEC 60076 for 50 Hz, with insulation levels for the 11 kV and 33 kV distribution 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 (Ceylon Electricity Board (CEB) and Lanka Electricity Company (LECO)); 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 Sri Lanka requires one.
