At METTZ Group, quality is not an afterthought; it is integrated into the very fabric of our process from inception to execution. Our commitment to producing high-voltage circuit breakers of the highest standards starts right from the developmental phase.
Design and Optimization
We employ state-of-the-art computer-aided calculations in our design phase to simulate and optimize various performance parameters. These parameters include switching performance, high-voltage stability, and mechanical load performance under both standard and extreme conditions, such as wind, short circuits, and seismic events.
Standardization and Continuity
The extensive standardization of main components across a variety of breaker types – including live tank, dead tank, and GIS – not only boosts the reliability and consistency of our products, but also enables us to maintain a steady and continuous production process. This consistency plays a crucial role in upholding our high-quality standards.
Quality Control
We utilize statistical quality control methodologies, leveraging the large volumes of units we produce to achieve high validity. All our circuit breakers undergo comprehensive type-testing in accordance with the latest IEC and ANSI standards before they are introduced to the market.
