Tower Testing and R&D

KPIL has a Tower testing and R&D station with sophisticated and state of art equipment that ranks it amongst largest and best of its kind across the world.

KPIL set up its own Tower Testing Station and R&D Centre near Gandhinagar using innovation in design and construction with the latest facility. It has capacity of
testing of testing up to 800 KV of Double Circuit Tower and 1200 KV of Single Circuit Tower, with 30×30 meters of base width and 85 meters of height. KPIL has successfully
tested more than 380 towers for various domestic and international clients ranging from 220 KV To 1200 KV.

KPIL’s strength is in its in-house R&D that is backed by a multi-disciplinary team of specialized engineers, sophisticated software and hardware facilities that provide
value-added integrated engineering services for clients as part of comprehensive EPC services.

The company’s tower testing station has been accorded “Recognition of In-house R&D center” by Ministry of Science and Technology, Government of India.
