In the year 1973, JAINCO commenced its manufacturing of small components and accessories of Transmission Line etc. in a small factory in Ichapur, Howrah. Gradually, machineries were installed to manufacture steel Fabricated Items like Arcing Horns, Yoke Plate, Sag Plate Extension Links, Straps, Midspan Joints etc. required for Transmission Lines up to 400kV and supplied to the then renowned Indian Manufacturers of Transmission & Distribution Line Materials. Simultaneously, it continued its regular manufacture & supply of Transmission, Distribution & Pole Line Products directly to various Indian & Overseas Power Utilities. Due to its product quality & committed delivery, amidst steep challenges, the company has earned reputation in National & International market and got approval from NTPC, NHPC, PGCIL, DVC and most of  the  other  leading  State  Owned  Power  Utilities  in  India  for  Supply  of  Transmission  & Distribution Line Materials, Pole Line & AB Cable Fittings & Accessories thereof.

The encouragement from the Top Indian Utilities & EPC Contractors, increasing demand of T&D Materials, Workload, in flow of orders had encouraged the Company to transfer its Unit in the year 2008 at Jalan Complex, Jangalpur, Howrah, an Industrial Belt situated by the side of National Highway No. 6 well connected to Sea Port, Rly. siding & Air Port . By the year 2018 the unit had total covered area of 2, 82, 000 Sq. Ft. housing Manufacturing & Testing Facilities. Total Area of the unit being 5,00, 000 Sq.
