Overhaul History : In 1997, all these generator sets had been overhauled in the original manufactory (De Laval Enterprise) and with Certification of overhauled

YOM : 1973

Running hours : about 41000 hours (total), 40000 hours (after overhaul)

Since 1973, these Gen-sets were working in a mine total 1000 hours (only for tested running) and then the mine was disused by government later. Since 1997, A National Power Plant purchased all of the sets as used equipment. Based on the national law rule, all the Gen-sets must have a overhaul certificate from the original manufactory, either new or used. So they hired the original manufactory (De Laval Enterprise) to overhaul all of the Diesel Engines and the Alternators, and upgraded the generator sets with PLC of GE FANUC. So, the total running is about 40000 hours from 1997 until 2004.

Quantity available for now : seven (7) sets of 6643 kW (rated output)
