Hindustan Zinc Ltd announced that its top-quality zinc has been used in the galvanization process for India’s heaviest power transmission steel pole structure.
The massive 400kV dual pole structure standing approximately 57m tall, underwent galvanization process utilizing a mix of Hindustan Zinc’s low-dross jumbo special high grade zinc and special high grade (SHG) zinc ingots.
The zinc galvanization process protects the intricate structure from corrosion and forms a barrier against air, water, heat and pollution thereby enhancing the structural integrity of the dual pole.
The structure, designed and manufactured by Skipper Ltd, is part of the 400kV Quad Moose double-circuit transmission line project under the proposed Pinnapuram Integrated Renewable Energy with Storage Project in Andhra Pradesh.
Skipper Ltd, India’s largest power transmission and distribution structure manufacturer, operates one of the country’s largest galvanizing facilities at its West Bengal plant.
Optimized design
The dual-pole structure weighing over 200 tonnes offers a significantly optimized design compared to traditional four-legged lattice towers, making it ideal for metro cities and urban areas with space constraints. The galvanized dual pole was dispatched to Andhra Pradesh, a coastal region prone to corrosion. Zinc’s protective layer is essential for coastal areas, where high humidity, salt and moisture accelerate corrosion and compromise structural integrity.
Why zinc?
Zinc’s sacrificial properties that protect steel make it vital for strengthening India’s infrastructure, including public infrastructure, railways, roadways, bridges and power transmission. The galvanization process acts as a continuous protective shield for steel, preventing corrosion, reducing maintenance and replacement costs.
Towards enduring infrastructure
Arun Misra, CEO, Hindustan Zinc Ltd, said, “At Hindustan Zinc,customer centricity is of paramount importance to us, and we are committed to providing our customers with innovative products who are creating enduring infrastructure for the country. By consistently collaborating with industry leaders like Skipper Limited, we are fortifying critical infrastructure projects across the nation. We are immensely proud to contribute to such an impactful project. As India’s focus on building world-class infrastructure intensifies, zinc galvanization becomes even more critical as it enhances longevity and ensures durability of such projects. Hindustan Zinc has been at the forefront of India’s industrial growth, and our zinc has consistently demonstrated its exceptional quality and performance.”
Strong partnership
According to Sajan Kumar Bansal, Managing Director Skipper Ltd, “The success of this project is a result of a strong partnership between industry leaders coming together to take the goal of Atmanirbhar Bharat ahead. Hindustan Zinc is a trusted supplier of top-quality zinc products that play a crucial role in ensuring the structural integrity and long-term durability of the structures we produce. The project’s completion is a significant milestone for India’s power infrastructure, and we are honored to have been a part of it.”
