At ETES 2025, hosted by Electrical Mirror, The Interview World engaged in an exclusive conversation with KP Singh, CMO of Nu-Cork Products Pvt. Ltd. He shed light on the company’s diverse product range, mapped out market opportunities, emphasized the critical role of transformer safety, and outlined Nu-Cork’s ambitious global expansion strategy. The following takeaways capture the essence of his powerful insights.
Q: Could you walk me through your products, what exactly you’ve developed, and how it is driving value or making an impact in the electrical industry?
A: Nu-Cork stands tall as a 35-year-old pioneer in transformer component manufacturing. Over the decades, the company has carved its niche by specializing in high-performance gaskets, air cells, and a wide range of critical transformer components.
The journey began with core gaskets. From there, Nu-Cork expanded its expertise into diverse rubber gaskets: neoprene, nitrile, whiton, fluorosilicon, and virtually every variant the industry could demand. Today, the company manufactures gaskets of every kind imaginable, setting benchmarks in precision and reliability.
Nu-Cork also leads in producing air cells for conservator tanks, a vital element in transformer performance. In addition, the company engineers air caster cushions, specialized solutions designed to move colossal equipment, including transformers weighing up to 500 tons. This innovation recently earned Nu-Cork the prestigious “Best Product” award at ELECRAMA, a recognition of global standing. Notably, Nu-Cork is the only manufacturer in India producing air caster cushions, a distinction that underscores its leadership and ingenuity.
Beyond innovation, the company champions national interest. By indigenously developing products that were once imported, Nu-Cork safeguards India’s foreign exchange and strengthens self-reliance. In doing so, it aligns seamlessly with the Prime Minister’s Make in India vision, contributing meaningfully to the nation’s industrial independence.
Q: How would you describe the market opportunity for your product, both globally and within the domestic market?
A: Nu-Cork primarily serves the transformer manufacturing industry, supplying critical components to nearly 750 transformer manufacturers across India. From global giants like Schneider, GE, and Hitachi to every major domestic player, all rely on Nu-Cork. They have no alternative. In transformers, sealing is non-negotiable, any leakage can be catastrophic. Nu-Cork ensures that never happens by delivering uncompromising quality.
This trust has translated into dominance. The company commands 70–80% of India’s market share. Beyond its strong domestic presence, Nu-Cork exports to more than 35 countries. Its footprint spans Asia, the United States, and Europe. The U.S. market, known for its stringent quality benchmarks, has already opened its doors to Nu-Cork, a testament to the company’s precision and reliability.
Nu-Cork is not resting on its leadership. It is scaling aggressively, already recognized as Asia’s largest in its space. With a growth trajectory of 40% CAGR, the company continues to accelerate. Remarkably, it has turned gaskets, often seen as low-cost items, into a powerful engine of revenue and growth.
Looking ahead, Nu-Cork has set its sights higher. With its pace of expansion and consistent performance, it is on track to become a $100 million company in the near future.
Q: What role does your product play in transformer manufacturing, and how does it contribute to enhancing safety?
A: Safety begins with sealing. Transformer leakage is not a minor flaw. It is a grave risk. Transformer oil is highly flammable, and even the slightest leak can trigger catastrophic fires. Nu-Cork’s gaskets eliminate that risk. They ensure absolute sealing integrity, safeguarding transformers and the systems they power.
But safety is only the beginning. By preventing leakage, these gaskets also optimize performance. They extend the operational life of transformers, enhance efficiency, and reduce maintenance costs. In short, Nu-Cork’s gaskets do more than seal. They protect, perform, and prolong.
When it comes to quality, Nu-Cork stands unrivalled. The company is second to none, not just in India or Asia, but across the world. While some Western competitors may generate higher revenues, none can match Nu-Cork’s commitment to quality and its vast industry reach. With more than 750 transformer manufacturers in India alone relying on its products, the company’s presence is both deep and decisive.
Nu-Cork is not merely supplying components. It is fortifying the backbone of global energy infrastructure.
Q: Are you looking to take your product to international markets?
A: Nu-Cork is expanding overseas at an aggressive pace. The company’s order book is robust and growing stronger by the day. In fact, demand has already outstripped current capacity. Despite doubling its infrastructure, Nu-Cork still faces the challenge of meeting this surge. Yet, as the leadership emphasizes, this is a good problem to have, one born of overwhelming customer trust.
Global clients now view Nu-Cork as the definitive source for gaskets and sealing solutions. This trust fuels its bullish outlook on international growth. While several strategic partners have expressed keen interest in collaboration, Nu-Cork remains confident in its self-sufficiency. At the same time, the company remains open. If a partnership aligns with its long-term vision and accelerates growth, Nu-Cork will embrace it.
Already, the company has advanced into both backward and forward integration, strengthening its value chain. Yet the vision extends further. Beyond transmission and distribution, Nu-Cork is actively exploring adjacent opportunities where strategic partnerships could play a pivotal role.
For Nu-Cork, the trajectory is clear: scale, leadership, and sustained global expansion, driven by unwavering customer confidence and a relentless pursuit of excellence.
