In the current market, the primary solutions for addressing harmonic issues are low-voltage tuning filter systems and low-voltage detuning filter systems. Harmonics can accelerate the aging of insulation in electrical equipment, and the voltage peak values resulting from harmonic superposition can significantly impact the aging of metallized film capacitors. The MK-CP low-voltage capacitor is specifically designed for use in low-voltage tuning filter systems and low-voltage detuning filter systems, with improvements in material selection, manufacturing processes, and testing methods. Power capacitors offer notable benefits in reducing system power losses, improving power factor, lowering operating currents, increasing grid voltage, and enhancing the operational margin of transformers. Additionally, they can be employed in filtering devices to mitigate harmonics. Utilizing compressed aluminum can sealing technology and undergoing two rounds of internal drying treatment before packaging, these capacitors employ dry gas and insulating materials as alternatives to traditional media like oil and sand. This approach eliminates the potential for filler materials to corrode metallized polypropylene films and sealing metals. With excellent insulation and heat dissipation properties, MK-CP capacitors ensure product stability and safety.
