When it comes to Smart Grids, the importance of ageing and endurance characteristics in high stress environments cannot be emphasised enough. Capacitors must cope in extreme ambient temperatures and electrical stress conditions. The same goes for metallised film (DC) and impregnated film-foil designs.
Work life: 30+ years
Films used for Smart Grids call for stable quality (AC/DC) and excellent endurance. Very low partial discharges and minor dielectric losses are also of utmost importance during a capacitor’s lifetime – as are good film uniformity and morphology.
To tackle these challenges, we specialise in extreme weather conditions, ranging from freezing arctic cold to consuming heat. In other words, we require each film to be fully operational, no matter what. Thanks to advanced PP technology with superior ageing characteristics we can now expect work life to exceed 30 years – without compromising capacitor performance.
High voltage philosophy
To ensure lifetime reliability, we only use advanced materials and dedicated processes. As market leader we base our knowledge on proven field records of HVAC and HVDC performance from the past 30 years (BOPP tenter and blown film technology).
We specialise in extreme weather conditions, ranging from freezing arctic cold to consuming heat. In other words, we require each film to be fully operational, no matter what.
The same high voltage philosophy is used for MET DC film applications, designed for the highest voltages and most extreme temperature stresses. We use modern tenter film and metallising technology for applications that require high reliability, e.g. wind farm converter stations. High voltage stress levels are applied in order to optimise space at installation sites.
