Logistics and network
Supplying Delhi.
Deliveries across Delhi start at about 120 km by road, which puts the nearer cities (North Delhi, New Delhi, South Delhi) within 2 days of dispatch. The state's demand centres on Okhla, Bawana, Narela and Mayapuri industrial areas, Delhi Metro and DDA works, data centres, commercial complexes.
Distribution in Delhi is handled by BRPL, BYPL, TPDDL and NDMC; Delhi Transco runs the transmission network. Programmes now in execution include Delhi solar policy, DISCOM network augmentation, 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.
