Logistics and network
Supplying Assam.
Deliveries across Assam start at about 1800 km by road, which puts the nearer cities (Bongaigaon, Guwahati, Tezpur) within 7 days of dispatch. The state's demand centres on Guwahati industrial area, tea estates, Numaligarh and Digboi refineries, Bongaigaon petrochemicals.
Distribution in Assam is handled by APDCL; AEGCL runs the transmission network. Programmes now in execution include RDSS, Assam distribution strengthening, 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.
