Today’s energy landscape is changing rapidly. Technological advancements, increased demand, aging infrastructure, and extreme weather events are only some of the issues currently facing the industry. Meeting these challenges requires a reliable, weather-hardened system that integrates distributed energy resources (DER) efficiently.

Ensure reliable power and signal transmission with hermetic feedthroughs. Our proprietary epoxy sealing process creates design flexibility, allowing you to work with virtually any electrical component to meet existing design challenges, or innovate to incorporate new technologies. Its chemically inert composition can be relied on for decades of use, no matter which liquid or gas is currently used within your power generation and distribution equipment.

Minimize Operational Disruptions

Hermetically sealed conductors prevent outside environmental interference with power and signal transmission to critical electronics. Expect reliable performance for decades, no matter how extreme outside weather conditions might become. Epoxy feedthroughs seamlessly integrate into the design of your substation’s equipment (transformers, switchgear, network protectors, and more), reducing costly weather-related failures.

Incorporating hermetic seals into condition monitoring equipment also aids in the prevention of eventual field failures. These feedthroughs ensure electrical signals accurately pass through a bulkhead without performance degradation, providing reliable health and other metrics of critical grid-supporting systems.

Maximize the Longevity of Your Existing Energy Infrastructure

Replacing substation assets is costly and the current grid is aging. Hermetically sealed condition monitoring devices can help you stay ahead of problem areas, reducing maintenance costs, prolonging asset life, and improving end-of-life planning.

In addition, the most cost-effective strategy in extending the lifetime of existing equipment is to monitor and replace smaller components prior to large-scale system failure. We can design turn-key solutions that can be easily installed into existing systems, ensuring optimal performance in this regard.

Applications

Hermetic feedthroughs are utilized in multiple areas of electrical generation and transmission. These include:

  • Liquid-filled Transformers
  • Gas-Insulated Switchgear
  • Network protectors
  • Waterproof and weatherproof substation electronics enclosures
  • High-voltage direct current (HVDC) systems
  • Generators
  • Energy storage
  • Nuclear power
  • Renewable energy
