Logistics and network
Supplying Sikkim.
Deliveries across Sikkim start at about 1520 km by road, which puts the nearer cities (Namchi, Gangtok) within 6 days of dispatch. The state's demand centres on Gangtok, pharmaceutical units at Rangpo and Namthang, hydro projects.
Distribution in Sikkim is handled by Energy and Power Department, Sikkim; Energy and Power Department runs the transmission network. Programmes now in execution include RDSS, 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.

Specifying
What changes for Sikkim.
- Design ambient 35 °C hill climate; seismic classification Zone IV for structures and foundations.
- Inland exposure: standard epoxy-polyurethane exterior finish and hot-dip galvanized steel parts.
- Temperature rise 45 K winding and 40 K top oil over the stated ambient, or 55 K / 50 K where Energy and Power Department specifications allow; losses, impedance and tapping to the utility schedule or IS 1180 level.
