Logistics and network
Supplying Tamil Nadu.
Deliveries across Tamil Nadu start at about 2240 km by road, which puts the nearer cities (Hosur, Vellore, Chennai) within 8 days of dispatch. The state's demand centres on Chennai and Sriperumbudur auto and electronics, Coimbatore pumps and motors, Tiruppur textiles, Hosur engineering, Salem steel, Tuticorin and Ennore ports, Tirunelveli and Ramanathapuram wind and solar.
Distribution in Tamil Nadu is handled by TANGEDCO; TANTRANSCO runs the transmission network. Programmes now in execution include RDSS, TANGEDCO solar and wind evacuation, 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.
