电力电容POLB UHD
超重负载(UHD)它是性能很高的LIFASA电容器系列,适用于具有一定谐波水平??的网络环境。无论是否安装有失谐电抗器,它们都具有较长的电气特性,可提供较长的使用寿命和出色的性能。
它是一种自修复电容器,具有低损耗金属化聚丙烯电介质,填充树脂。它们具有超压断开系统,通过切割3相提供高水平的内部缺陷安全性。铭牌包含相关的QR码,允许您下载个人例行测试证书,并且还提供防复制保护。
Power Capacitor POLB UHD
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.
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.
