Our high voltage transformers are engineered for reliable operation in demanding transmission, distribution, and specialised industrial applications. Designed to handle elevated voltage levels with precision, they incorporate advanced insulation systems, high-grade core materials, and robust winding construction to ensure superior dielectric strength and minimal energy losses. Suitable for both indoor and outdoor installations, these transformers deliver excellent voltage regulation, high thermal stability, and long-term operational reliability in critical high-voltage environments.

How is a High voltage transformer designed?

High voltage applications place strict demands on transformer design. At Etal, each solution is carefully engineered to withstand electrical, thermal, and mechanical stresses over extended operating lifetimes. Optimized insulation systems, precision winding layouts, and controlled manufacturing processes help reduce partial discharge risk and ensure consistent performance even under harsh operating conditions.

Our high voltage transformers are designed to meet industry requirements across a wide range of applications, including power transmission equipment, industrial systems, testing environments, and high‑frequency power electronics.

Toroidal, Laminated, and Ferrite Core Technologies

Etal manufactures high voltage transformers using toroidal, laminated, and ferrite core designs, allowing the technology to be matched precisely to the application requirements.

Toroidal high voltage transformers offer compact size, low stray magnetic fields, and high efficiency, making them ideal for space‑constrained systems and applications requiring low noise and tight magnetic control.

Laminated core transformers provide robust mechanical construction, flexible design options, and excellent performance in higher‑power and custom‑format applications.

Ferrite core transformers are well suited for high‑frequency and high‑voltage applications, offering low core losses, high efficiency, and stable behavior at elevated switching frequencies.

By offering multiple core technologies, Etal ensures the optimal balance of performance, efficiency, and reliability for each high voltage application.

Custom‑Engineered High Voltage Solutions

In addition to standard designs, Etal specializes in custom‑engineered high voltage transformers, developed in close collaboration with customers. Our engineering teams support projects from concept and prototyping through qualification and series production, ensuring each solution meets exact electrical, thermal, and mechanical requirements.
