单相高压电容器
Lifasa的cosφ校正电容器和AT的谐波滤波器是在不锈钢容器/盒底座和陶瓷端子下制造的。
带有内部保险丝的单相(1或2端子),用于通过双星连接电源。推荐用于11 kV以上的电压网络或需要大功率设备。
Single phase high voltage capacitors
Lifasa’s cos ? correction power capacitors and harmonic filtering for AT are manufactured under the stainless steel container/box base and porcelain terminals.
Single-phase (1 or 2 terminals) with internal fuses for connection to the mains via a double star. Recommended for voltage networks above 11 kV or need of high power equipment.
