Vermiculite is a dry, granular insulating material that is solid, inert and fire proof. This material fills all open spaces in the enclosure to isolate the capacitor elements and exclude free oxygen.
All capacitors normally experience insulation breakdown as a result of the accumulated effect of temperature, voltage stress, impurities in the insulating medium, etc. When this happens in a non-"metallized" design, the electrodes are short-circuited and the capacitor ceases its production of reactive power.
New technologies and the demand for improved productivity levels have a high impact on the materials used for the construction of capacitors. These materials must meet the rigorous demands of the industry. In addition, trends like e-mobility are driving the development of new materials that can withstand severe conditions and stresses.
ABB Low Voltage capacitors contain no free liquids and are filled with a unique nonflammable granular material called vermiculite.
Ceramic capacitors use ceramics as a dielectric, stacked with metal layers. These devices are ideal for applica-tions with high voltage, high frequency, high power demands, and high temperatures, like the petroleum, automotive, avionics and other industries, and as multi-layer ceramic capacitors (MLCCs).
ABB metallized-film design losses are limited to .5 watts per kvar including the losses across the discharge resistors. Due to the thin electrode and dielectric, metallized-film elements are small and compact in size resulting in smaller, more powerful capacitors.
