Logistics and network
Supplying Ladakh.
Deliveries across Ladakh start at about 770 km by road, which puts the nearer cities (Leh) within 4 days of dispatch. The state's demand centres on Leh and Kargil, defence establishments, renewable park at Pang.
Distribution in Ladakh is handled by Ladakh Power Development Department; Ladakh Power Development Department runs the transmission network. Programmes now in execution include Ladakh 13 GW renewable project, grid connectivity works, and each is tendered against a technical specification that we quote and manufacture to.
The power transformer line closed the last gap in the chain. Between distribution and power class we now cover 16 kVA right through to 20 MVA — a span very few regional manufacturers hold on a single site.
The standard substation build is 33/11 kV, Dyn11, ONAN, with an off-circuit tap changer at +5% to −10%. Where the network needs voltage regulation under load we fit an on-load tap changer at +5% to −15%, and where the load profile justifies forced cooling we supply ONAF with a rated output at each cooling stage.

Specifying
What changes for Ladakh.
- Design ambient 35 °C, high altitude cold; 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 Ladakh Power Development Department specifications allow; losses, impedance and tapping to the utility schedule or IS 1180 level.
