Power Capacitor POLB UHD
POLB UHD电力电容器
Ultra Heavy Duty (UHD) it is the highest performance LIFASA capacitor series, for those network environments with certain level of harmonic. Whether installed with or without detuned reactors, they offer long time life expectancy and outstanding performance with its higher electrical characteristics.
超重载（UHD）是LIFASA系列性能最高的电容器，适用于一定谐波水平的网络环境。无论是否安装失谐电抗器，它们都以其较高的电气特性提供长的预期寿命和卓越的性能。
It is a self-healing capacitor with low losses metallized polypropylene dielectric, filled with resin. They have an overpressure disconnection system which provides a high level of safety against internal defects by cutting the 3 phases. The name plate includes a QR code associated, allowing you to download the individual routine test certificate, and it also offers an anti copy protection.
它是一种自愈合电容器，具有低损耗金属化聚丙烯介质，填充树脂。它们具有超压断开系统，通过三相断开来提供针对内部缺陷的高度安全性。该铭牌包括相关的二维码/条形码代码，允许您下载单独的例行/常规测试证书，并且它还提供防复制保护。
