View Details15 dry-type transformers for Mumbai industrial park indoor substations, ensuring fire safety for manufacturing facilities.
A major industrial park development in Mumbai, India required reliable power distribution for multiple manufacturing tenants. Transformer Co. provided 15 units of dry-type transformers for indoor substations, ensuring fire safety and minimal maintenance.The project supports over 50 manufacturing facilities in the park, with a total installed capacity of 15 MVA.
Operating in a tropical climate with extreme heat and humidity presented significant engineering challenges. Standard transformer designs would struggle under ambient temperatures regularly exceeding 40°C, requiring specialized insulation systems and robust cooling solutions to maintain reliable performance. Additionally, the logistics of delivering oversized equipment weighing over 120 tons each to sites in Lagos and the landlocked capital Abuja demanded innovative transport planning and modular packaging strategies to navigate Nigeria's road infrastructure.
We engineered custom-designed insulation systems rated for 55°C ambient temperature, exceeding the standard 40°C rating by a significant margin. Enhanced ONAF cooling with additional radiator banks was implemented to ensure optimal thermal management under peak load conditions. For logistics, we developed a modular packaging approach that allowed road transport to remote locations, with components reassembled on-site. Our engineering team provided comprehensive site supervision throughout the 18-month installation period, ensuring every unit was commissioned to exacting standards.
