Photo Gallery
On Republic Day of 2005, after hoisting the National Flag, all the employees working at 220 
kV sub station, Lalton Kalan declared to make it the best maintained sub station. The photo of this event is displayed in at the main enterance. On the same day, the loby of the control room was converted into a photo gallery. Nine number framed prints of the photos of size 2 x 1.5' are displayed. Some poetry pieces are also displayed. Mr. Ganga Parsad, the junior most employeeinaugrated this gallery in the presence of Er. M. S. Bajwa then Dy. Chief Engineer P&M, PSEB Ludhiana.
