BPFMJ series self-healing LV submerged - are furnace purposed capacitor adopts the international advanced silver-Zn-al compound edge thickened metallized film. The company introduces international advanced equipment and technology, carries out production strictly according to IEC60831.1 :1996. The products are mainly applied to secondary LV reactive compensation of submerged-are furnace, used to improve the power factor and reduce reactive power of smelting system, reduce power consumption, increase smelting voltage compensate voltage drop of short net; it provides new ways for energy saving for high energy consumption enterprise, really is the ideal product responding to the energy saving recommendation of the government.
Features:
As it takes silver-Zn Al compound edge thickened metallized film as medium, it has advantages of compact volume, light weigh, stable performance, etc. Low loss, actual value lower than 0.1% ,consequently , the capacitor itself is featured with low energy consumption, low heat, low temperature rise, long service life, favorable energy saving efficiency. Excellent self-healing property: Partial breakdown of medium caused by over - voltage can self-heal quickly, and resume normal operation. This property improves the reliability of product sharply. Safety: Inner installed with self-discharge resistance and safety device, it is safe and reliable to operate. Oil tight: It adopts special material as impregnate, it will be in solid state at normal temperature, melting point higher than 75ºC ,oil tight and avoid environmental pollution during operation.
