Mehru Electrical & Mechanical Engineers Pvt Ltd, a material subsidiary of Quality Power Electrical Equipments Ltd. (QPEEL), has announced the signing of a landmark co-development agreement with Hyosung T&D India Pvt Ltd, a wholly-owned subsidiary of Hyosung Heavy Industries Corporation, Korea, for gas- insulated switchgear (GIS) instrument transformers.
This milestone positions Mehru as one of the first Indian companies to co-develop GIS instrument transformer technology for global markets, a release from QPEEL said.
World-class GIS components
The collaboration brings together Hyosung’s global leadership in advanced equipment and eco- friendly gas technologies with Mehru’s expertise in manufacturing high-voltage instrument transformers, enabling the creation of world-class GIS components designed and manufactured in India. The agreement marks a pivotal step in reducing India’s dependence on imports, directly supporting the Government of India’s “Make in India” vision, and positioning the country as a credible global supplier in the fast-growing GIS segment.
Diversification into GIS value chain
This development enables Mehru to diversify into the GIS value chain, extend its leadership in oil- filled and dry-type transformers, leverage Hyosung’s expertise in eco-friendly gases and compact equipment design, and to address new demand segments such as metro rail, offshore wind, data centers, and high-voltage urban transmission projects. The products to be developed under this partnership will be tested and certified to IEC/IEEE international standards, strengthening Mehru’s global technology credentials and enabling higher value creation per product. The development and commercialization of the initial set of transformers is expected within the next 12 months.
New exports frontier
According to Bharanidharan Pandyan, Joint Managing Director, QPEEL, “By bringing global GIS technology to India, we are opening new frontiers for exports, achieving true self-reliance, and embedding India on the global map of advanced T&D manufacturing. This marks a proud milestone in Mehru’s journey and underscores our commitment to innovation and technological leadership.”
Global GIS market
Gas-insulated switchgear (GIS) is one of the fastest-growing sectors in the transmission and distribution industry. Unlike conventional air-insulated substations, GIS offers compact design, enhanced reliability and safety, and environmentally responsible innovation with alternatives to SF₆ gas. The global GIS market is projected to grow at a 7–8 per cent CAGR through 2030, driven by renewable integration, urbanization, and grid modernization. India has traditionally relied on imports for GIS equipment, with major suppliers based in Europe, China & Japan, the release noted.
