Logistics and network
Supplying Andaman and Nicobar Islands.
Deliveries across Andaman and Nicobar Islands start at about 3210 km by road, which puts the nearer cities (Port Blair) within 11 days of dispatch. The state's demand centres on Port Blair, island diesel and solar grids, shipping.
Distribution in Andaman and Nicobar Islands is handled by Electricity Department, Andaman and Nicobar; Electricity Department runs the transmission network. Programmes now in execution include Island solar and submarine cable programmes, and each is tendered against a technical specification that we quote and manufacture to.
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.
