Yash Highvoltage: Understanding the Business & How It Makes Money
When people think about the power industry, they usually think of power plants or transformers. However, a small component inside every transformer is equally important. It is called a transformer bushing.
Yash Highvoltage operates in this niche segment. The company manufactures condenser-graded high-voltage and high-current transformer bushings. These products serve the power transmission and generation industry. Since its incorporation in 2002, Yash has supplied more than 45,000 transformer bushings worldwide. Today, it is one of the few independent transformer bushing manufacturers globally and the only independent manufacturer in India.
Unlike transformer manufacturers, Yash does not build complete transformers. Instead, it manufactures one of their most critical components. A transformer bushing creates a safe and insulated path for electricity to enter and exit the transformer. Without it, electricity cannot safely pass through the transformer's metal body. As a result, the transformer cannot operate reliably.
This places Yash in a highly specialized part of the power equipment value chain. Every high-voltage transformer requires multiple bushings. According to the company, there is no substitute for this component. Demand for bushings therefore grows with new transformers. As power grids expand, utilities install more transformers. That directly creates demand for Yash's products.
Rather than generating electricity or manufacturing complete transformers, Yash earns its revenue by supplying these mission-critical components to transformer manufacturers, power utilities, and international customers. Understanding the role of a transformer bushing is the first step to understanding Yash Highvoltage's business model.
What Is a Transformer Bushing?
A transformer bushing is a specialized electrical insulation component. It creates a safe path for electricity to enter and exit a transformer.
At first glance, a bushing looks like a simple porcelain or polymer cylinder. In reality, it is a highly engineered component designed to handle extremely high voltages and currents.
To understand its importance, imagine a high-voltage cable carrying 220 kV, 400 kV, or even 765 kV electricity. This cable must pass through the transformer's grounded metal tank to reach the windings inside. If the conductor touches the metal body directly, it can cause a short circuit, damage the transformer, and even lead to catastrophic failure.
A transformer bushing prevents this. It electrically insulates the live conductor from the grounded transformer body while allowing electricity to flow safely through it. In simple terms, it acts as a high-voltage gateway between the outside power network and the transformer's internal electrical system.
Because every power transformer needs multiple bushings, they are an essential part of the power transmission network. According to Yash Highvoltage, there is no substitute for transformer bushings, making them an indispensable component in every high-voltage transformer.
Why Are Transformer Bushings So Important?
A transformer bushing may look like a small component, but it performs a critical function. Its failure can bring an entire transformer out of service.
Power transformers operate under extreme conditions. They handle very high voltages, heavy electrical loads, lightning surges, heat, pollution, and moisture. The bushing must continue to insulate the live conductor under all these conditions. Even a small insulation failure can damage the transformer and interrupt power supply.
A failed transformer is expensive to repair or replace. It can also disrupt electricity transmission, delay industrial operations, and increase maintenance costs. For utilities and transformer manufacturers, reliability is therefore more important than the cost of the bushing itself.
This is one reason why customers prefer proven suppliers with a long operating history. According to Yash Highvoltage, transformer bushings are mission-critical components with no substitute, making quality, testing, and long-term performance essential factors during supplier selection.
Since a single transformer usually requires multiple bushings, demand for these components grows alongside transformer installations. Every new transmission project, substation expansion, or transformer replacement creates fresh demand for bushings.
Yash Highvoltage's Product Portfolio
Yash Highvoltage manufactures a range of high-voltage and high-current transformer bushings used in power generation, transmission, and distribution networks. Each product is designed for specific voltage levels, current ratings, and operating conditions. This enables the company to serve transformer manufacturers, power utilities, EPC contractors, and industrial customers.
Although Yash offers multiple products and aftermarket services, its business is heavily concentrated in three core product categories. In FY26, RIP Bushings contributed 82% of revenue, followed by OIP Bushings at 10% and High Current Bushings at 5%. The remaining 3% came from other products and service-related activities.
1. Resin Impregnated Paper (RIP/RIS) Bushings
Revenue Contribution: 82% (FY26)
RIP/RIS Bushings are Yash Highvoltage's flagship products and the company's largest revenue driver. These bushings use resin-impregnated paper or resin-impregnated synthetic insulation, eliminating the need for insulating oil. As a result, they require less maintenance, reduce the risk of oil leakage, and offer higher operational reliability.
The company manufactures RIP/RIS bushings for a wide range of voltage classes and is expanding into 245 kV, 420 kV, and 550 kV products to address higher-value market segments. It is also setting up localized manufacturing of RIP/RIS cores, which were previously imported. This is expected to strengthen backward integration and support export growth.
RIP/RIS Bushings generate more than four-fifths of Yash's revenue. This makes them the company's primary growth engine and the most important product to track.
2. Oil Impregnated Paper (OIP) Bushings
Revenue Contribution: 10% (FY26)
OIP Bushings use oil-impregnated paper as the insulation medium. They are widely used in conventional power transformers and continue to serve a large installed base across transmission and distribution networks.
While this is a mature product category, it remains an important part of Yash's portfolio. The company continues to develop new OIP products for specialized applications, including STATCOM systems and international markets.
OIP Bushings provide stable demand from existing transformer installations. They also generate replacement and refurbishment opportunities throughout a transformer's operating life.
3. High Current Bushings
Revenue Contribution: 5% (FY26)
High Current Bushings are designed for applications that require extremely high current-carrying capacity while maintaining reliable electrical insulation. These products are used in specialized industrial equipment and high-capacity power systems where performance and reliability are critical.
Although this segment contributes a smaller share of revenue, it demonstrates Yash's engineering expertise in manufacturing technically demanding products.
High Current Bushings strengthen Yash's presence in niche applications and diversify its product portfolio beyond conventional transformer bushings.
4. Supporting Products & Services
Besides its three core product categories, Yash manufactures several specialized bushings, including Wall Bushings and Oil-to-Oil Bushings. The company also provides a range of aftermarket services such as:
