TESTING FACILITY

FACILITIES

APT works division is facilitated with fully established workshops (2 units) to take care of major Repair/Re-work/Services and supply of Spares for TG set and its auxiliaries. The APT workshop facility is sophisticated to undertake repair and rework of higher capacity TG sets of up to 250 MW.

APT can meet any spare parts supply needs through the inhouse facilities and reverse engineering or through our network. If necessitated, repairs can be carried out in the field to the extent possible and if the repairs require additional machining, it can be completed at our facility. Our workshop is also approved by IBR authorities for the manufacturing of equipments with IBR stamping.

  •   Unit 1 having a working area of 1000 Sq. Yards.
  •   Unit 2 having a working area of 8000 Sq. Yards.
