Transmission & Distribution Components Laboratory
Transmission & Distribution (T&D) plays a vital role in the power sector. The main emphasis of evaluation of T&D items is their durability under all possible operational & environmental conditions. ERDA with its state-of-the-art T&D components Laboratory is undertaking evaluation of various types of conductors (including HTLS & OPGW) insulators and T&D Hardware.
