The BSMJR series submerged arc furnace power capacitors use advanced trajectory nickel zinc aluminum composite edge thickening metallized film as the material. Introduce international advanced equipment and technology, strictly follow the international IEC60831.1:1996 standard for production, mainly used for secondary low-voltage reactive power compensation of submerged arc furnaces, improve power factor, reduce reactive power of smelting systems, reduce power consumption, increase electrode end non smelting voltage, compensate for voltage drop of short networks, etc; This provides a new way for high energy consuming enterprises to save energy and power consumption. It is a highly recommended energy-saving product by the country.
