As India moves toward its goal of a $5 trillion economy, the demand for robust electrical infrastructure has never been higher. With the massive expansion of the National Smart Grid and the implementation of schemes like the Revamped Distribution Sector Scheme (RDSS), surge arresters (Lightning Arresters) have become critical components for ensuring grid stability.
India’s diverse climate—ranging from high-humidity coastal regions to arid deserts—requires surge arresters with superior sealing and anti-pollution characteristics. Our Zinc Oxide (ZnO) arresters are designed specifically to withstand the volatile voltage conditions often found in Indian rural and urban distribution networks.
Transition from gap-type to Gapless Metal Oxide Surge Arresters (MOSA) is now standard across PowerGrid projects in India.
Rise of Renewable Energy Corridors in Rajasthan and Gujarat requires specialized protection for solar inverters and wind turbine transformers.
Wenzhou Shuguang Fuse Co., Ltd. (formerly Yueqing Shuguang Fuse Factory, est. 1992) has been at the forefront of power technology for over three decades. Located in the electrical capital of China, we have become a premier partner for Indian suppliers and factories looking for high-reliability surge protection.
Our products are designated by the Ministry of Electric Power Industry to produce high-voltage current-limiting fuses, zinc oxide arresters, and insulators. We strictly adhere to IS/IEC standards to ensure seamless integration with Indian power equipment.
Protecting underground cabling and compact substations in emerging smart cities like Pune, Surat, and Varanasi from transient overvoltages.
Customized 1000V/1500V DC surge arresters for solar PV arrays in the Pavagada Solar Park and Bhadla Solar Park regions.
Reliable protection for steel plants and automotive hubs in Chennai and Jamshedpur, where motor switching causes frequent surges.
The "Shu Rong" brand is synonymous with durability. Our rapid development in recent years is attributed to our insistence on high-quality raw materials and sophisticated testing equipment. For the Indian market, we provide Polymeric Housed Surge Arresters which offer better safety against explosion and are lighter for easier installation on Indian distribution poles.

India’s electrical grid is undergoing a seismic shift. With the government’s push for "Power for All," the reliability of distribution transformers has become paramount. Surge arresters act as the first line of defense against lightning strikes and switching surges that can cause catastrophic equipment failure and prolonged blackouts.
Lightning activity in India is particularly intense during the monsoon season. States like Odisha, West Bengal, and Bihar record some of the highest lightning frequencies globally. Standard arresters often fail due to moisture ingress or inadequate thermal capacity. Our Zinc Oxide Arresters feature a robust multi-seal design that prevents moisture entry, making them ideal for the humid Indian climate.
While many Indian factories assemble components, the core technological resistor blocks (the heart of the arrester) require precision engineering. Wenzhou Shuguang provides these high-performance blocks and complete assemblies to various provincial power companies across India, ensuring that local infrastructure meets global standards like IEC 60099-4.
India is a global leader in renewable energy. However, solar and wind installations are often located in open terrains, making them prime targets for lightning. Our surge arresters are optimized for low-residual voltage, ensuring that sensitive power electronics in solar inverters are protected, thereby reducing the O&M costs for Indian renewable energy developers.
Whether you are a distributor in Delhi, an EPC contractor in Bangalore, or a factory owner in Mumbai, we provide the protection you need.
