Hydro Industry Solutions

As leading manufacturers of high-quality HV diamond coils and windings for over 55 years, Preformed Windings are well placed as preferred suppliers and partners to hydro industry customers across the world. In fact, our confidence in the quality of our products allows us to provide our partners with up to 10-year warranty on our award winning QualCoil products. Preformed Windings are also progressively supporting projects where increased generation output is required and a long service life with minimal maintenance is critical.

Preformed Windings QualCoil diamond coils are the highest-quality coils available with benefits such as the lowest Partial Discharge (Pd) levels in the industry, the best Tan Delta levels, extended service life and reduced maintenance. Our extensive experience passing thermal cycle and voltage endurance testing at independent test facilities in addition to our CAD design process and state-of-the-art manufacturing facilities and processes result in a tried, tested and low-risk solution. We have manufactured thousands of hydro coils for customers globally up to 18kV and 95MW.

The International Energy Agency (IEA) says we must double hydropower capacity by 2050 if we are to meet the Paris climate targets. However, many existing hydro facilities in the US and Europe are old, and there are limited opportunities to build new ones. The answer? Refurbish existing facilities to make them more efficient, increase output, and increase their lifespan, and all while reducing maintenance requirements.

The first port of call is the generators. The beating heart of a hydro plant, well-maintained and properly equipped generators are critical to the overall efficiency of a power plant. One of the most essential components of the generators are the high voltage coils. However, hydro generator insulation systems have a finite life and generally need to be rewound after 40 to 50 years. Using the right coils is a critical part of the refurbishment and can help energy companies meet or exceed their efficiency targets. Preformed Windings are answering this call by offering improved diamond coils offering increased output levels, long service life and reduced maintenance

As thought-leaders in the industry Preformed Windings are active members of NHA and IHA sharing our technical expertise and knowledge with the industry.  As independent product manufacturers we do not compete with our partners for service work which allows Preformed Windings to carry out significant R&D activities with the most respected OEM’s and insulation suppliers in the industry resulting in cutting-edge specifications such as QualCoil H, the worlds’ first class H resin rich specification in the world.
