POLT 三相圆柱形电容器
POLT 三相圆柱形电容器
0.5...7.5kvar THREE-PHASE CYLINDRICAL CAPACITOR
Description 产品简介
Self-healing capacitors with low losses metalized polypropylene dielectric without liquid impregnants. They have an overpressure disconnection system that disconnects the capacitor in case of any internal failure. Capacitors in cylindrical aluminium cans, provided with a M12 stud for fixing and earthling.
Connection is made by a double 6.35 mm Faston terminal. Optionally, provided with discharge resistors for external connection. These capacitors are especially suitable for the individual compensation of small inductive loads and the construction of small capacitor banks. They have discharge resistors externally fitted.
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。它们具有过压断开系统，可在发生任何内部故障时断开电容器。圆柱形铝罐中的电容器，配有用于固定和接地用的M12 螺柱。
通过双6.35 毫米 Faston 端子进行连接。 提供用于外部连接的放电电阻器（可选）。 这些电容器特别适用于小型感性负载的单独补偿和小型电容器组的构建。 它们具有外部安装的放电电阻器。
