LOW VOLTAGE CAPACITORS

ABB's CLM Drange of capacitors comprises a number of wound elements and a dielectric made of metallised polypropylene film. These dry windings are provided with Sequential Disconnector ensuring that each element can be reliably and selectively disconnected from the circuit at the end of its life. The capacitor elements are treated in vacuum to ensure optimal electrical is characteristics. Each winding placed in a plastic case and encapsulated in thermo-setting resin to obtain a perfectly sealed element. The elements are placed inside a sheet steel box and connected to enable single or three phase power supply at the required voltage and frequency. The sheet steel is filled with inorganic, inert and fireproof granules, which absorb the energy produced and act as a fire retardant. The CLMD capacitor also has thermal equalizers to ensure effective heat dissipation.
