Frequency Converter used Power Cable

Frequency Converter used Power Cable

Low voltagefrequency converter cables

1.Range ofapplication

This product can be applied in power supply of frequency converter controlling system with 0.6/1kV and below AC rated voltagelt is with good voltage impact resistance which can with-stand the impulse voltage in frequency convertinq;meanwhileit is with good shielding property which can eliminate the elec.tromagnetic interference and decrease the noise of frequencyconverter motor so as to guarantee the steady operation of systems.lt is widely applied in metallurgy,power supply,petroche-mical industry,etc
