Choke Explosion-Proof SKS-FB-Series
Description of AC Choke：
FB series industrial explosion-proof chokes are placed in cruel working conditions.High reliability and safety, taking full consideration of the special mining circumstance, strong in structural strength and high in insulation. With low temperature rise and little leakage current, improving the input current waveform and balance degree, restraining high harmonic, limiting operating impulse and power factor.
Material Features of AC Choke：
Flexible Installation Choice：Compact structure, easy installation, stable performance and strong anti-short circuit ability; Excellent Property：Using South Korean magnetic power, low core loss,suitable for high frequency, strong overload demand.
Reliable Performance：VPI process makes immersion oil fully, thicker oil film and good corrosion resistance as well as moisture proof performance. H class insulation, improving the reliability of long-term operation.
Low Noise and temperature: Temperature-rise less than 70K, noise less than 70Db. The magnetic powder density is low and weight is light.
