MV POWER CAPACITORS
The MV power capacitors (single and three phase) are mainly used in 50Hz or 60Hz AC power systems to improve power factor. Reduce reactive power loss, improve voltage quality, and give full play to the efficiency of power generation and power supply equipment. Single-phase capacitors (1 or 2 terminals) with internal fuses for connection to the mains via a double star. Recommended for voltage networks above 12 kV or need of high power equipment. Three-phase capacitors (3 terminals) with internal fuses for direct connection to three-phase mains. Recommended for voltage networks below 12 kV. Apart from a long operating life and high current and voltage load capacity, high density, safety is crucial advantages of the compact technology components in MV capacitors. Other features are good heat dissipation, low self-heating as well as reliable performance at high ambient temperatures and greater dielectric resistance Volt/μ.OVERVIEW
Our MV power capacitors have a dielectric constituted in general by three polypropylene films “hazy”, rough in both faces, of high purity. This construction, instead of which it uses only two layers of a rough film in a single one of his faces, common in other manufacturers, confers to MV power capacitors greater security of operation and greater life utility. The rough of both faces of polypropylene is a condition indispensable for the complete impregnating of the film during the process and, therefore, for the stability of the capacitor in the long term. Capacitors use exclusive impregnating non PCB, biodegradable y non-toxic. This it is characterized by his high flash point, great capacity of gas absorption derived from the internal electrical un loadings, and total environmental compatibility (biodegradable). MV capacitors uses conservative criteria of design that imply the application of dielectric efforts (kV/mm) relatively low on the materials. Like consequence, the capacitors are of dimensions somewhat greater than those of other marks, with an expectation of greater life utility. The characteristics of their design, the rigorous selection of the manufacture materials and the artisan care put in their construction and process give like result capacitors of low losses, which is translated in smaller this form and operating temperatures, a greater life utility. Incorporates to a great part of their range of MV. capacitors (specially for the greater powers) with the option of individual inner fuses by coil, of new design. Such they allow to isolate the possible failure of anyone of the elements of the capacitor and other elements can still work in normal condition. The fuses are separated to each other, so that it is impossible that the performance of one of them causes the Acting of the fuse next to. In addition, the condensers with internal fuses allow simpler, light and economic constructions.
