MFB 紧凑型三相电力电容器
MFB 紧凑型三相电力电容器
1...25 kvar COMPACT THREE-PHASE POWER CAPACITOR
Description 产品简介
Self-healing capacitors with low losses metallized polypropylene dielectric without liquid impregnants. Mounted in rectangular sheet steel plate enclosure having discharge resistors connected to the terminals, which are protected by the cover.
These capacitors are especially suitable for the individual compensation of inductive loads and the construction of capacitor banks.
具有低损耗金属化聚丙烯电介质的自愈式电容器，无液体浸渍剂。安装在矩形钢板外壳中，放电电阻连接到端子，由盖子保护。
这些电容器特别适用于感性负载的单独补偿和电容器组的构造。
