PRISMATIC CAPACITOR TECHNOLOGY
棱柱电容器技术
LIFASA capacitors are manufactured using the most advanced technologies, coming from an in depth knowledge of the manufacturing process and also from very strict laboratory and R+D tests. The enormous experience in installations, acquired over many years, allow us to incorporate in the new design the necessary characteristics to optimize the use of the product. Capacitors are composed of capacitive elements wound from low loss polypropylene film. This dielectric is vacuum metallized, what gives it an excellent self-healing characteristic (MKP). Elements are covered with a thermo hardening resin of high dielectric properties and are not oil filled. Elements are connected to obtain the required reactive power and are mounted in steel cases. Void spaces between elements and the case are filled with a non-flammable, inert and non toxic material. Each element is individually protected. This construction system avoids any risk of explosion of the capacitor and meets all the tests specified in the IEC 60831-1 and IEC 60831-2 standards.
LIFASA电容器的制造采用先进的技术，来自对制造工艺的深入了解，也来自非常严格的实验室和研发测试。多年积累的丰富的安装经验使我们能够在新的设计中结合必要的特性来优化产品的使用。电容器由低损耗聚丙烯薄膜缠绕的电容元件组成。这种电介质是真空金属化的，使其具有优良的自愈特性（MKP）。元件被高介电性能的热硬化树脂覆盖，并且不填充油。连接元件以获得所需的无功功率并安装在钢箱内。元件和壳体之间的空隙填充有不易燃、惰性和无毒的材料。每个元素单独保护。此构造系统避免了电容器爆炸的风险，并且满足IEC 60831-1和IEC 60831-2标准中规定的所有测试。
ADVANTAGES 优点
- Capacitors are dry type and consequently ecologically safe: there is no possibility of impregnating liquid leakage.
电容器是干式的，因此在生态上是安全的：不存在浸渍液体泄漏的可能性。 - Losses are specially reduced: lower than 0.05% (< 0.5 W/kvar).
损耗被特别地降低：低于0.05%（＜0.5 W/kVaR）。 - Capacitors are a self-healing type: in case of a dielectric breakdown, due for example, to a transient overvoltage, the self-healing mechanism vaporizes the metallic electrode around the breakdown point, allowing the capacitor to go on working normally.
电容器是自愈类型：例如在由于瞬时过电压而导致介电击穿的情况下，自愈机制在击穿点附近使金属电极蒸发，允许电容器正常工作。 - Their weight and volume are very low, allowing them to be installed everywhere without problems.
它们的重量和体积非常低，允许它们安装在任何地方都没有问题。 - Capacitors use strong terminals that guarantee a fast and safe connection.
电容器使用坚固的接线端子，保证快速和安全的连接。 - Capacitors, cover with their different series, a wide range of power and voltages to satisfy the most varied requirements.
电容器，覆盖不同的系列，宽泛的功率和电压范围以满足绝大部分不同的要求。
