Rongxin Power Engineering (RXPE) is a leading international developer and provider of high voltage power electronic solutions.


Global demand for steel continues to grow and if you intend to be part of this boom, you’ll want to boost the throughput and production volume of your plant. What you need now is an electric arc furnace that is simply top of the line. That combines high capacity with maximum availability. That flexibly processes different charging materials. That can produce a range of steel types – without long tooling times that slow down production. At the same time, it is crucial to reduce costs – both when investing and during ongoing operations. To do this, you need simple, consistent operation, components with a long service life, ease of maintenance and reduced manpower requirements. And naturally, you also need to limit the impact your plant has on the environment. To ensure that you can comply with all regulations into the future – and to fulfill your responsibility for ensuring a clean environment. Is there one solution that meets all these needs? TAKFA with regards to its partners can supply ultimate solution for EAF. As the product of continuous development improvements, our furnaces features maximized power-on-time, high-speed movements and easy access to all components for maintenance. The furnace is ideal for ultra-high-power input and overall furnace performance can be additionally enhanced with the latest technologies.



POWER Quality Solution (SVC, STATCOM)

A Static VAR Compensator (SVC) is an electrical device for providing fast-acting reactive power compensation on high-voltage electricity transmission networks to control dynamic voltage swings under various system conditions and thereby improve the power system transmission and distribution performance. SVCs are part of the Flexible AC transmission system device family, regulating voltage and stabilizing the system.

Electrical loads both generate and absorb reactive power. Since the transmitted load varies considerably from one hour to another, the reactive power balance in a grid varies as well. The result can be unacceptable voltage amplitude variations, a voltage depression, or even a voltage collapse.

One of the main Application of SVC is in the steel making industries where the EAF and LF are working. Due to the reactive and active impulse caused by the operation of EAF, the system voltage is fluctuating and flicking. The harmonic current caused by EAF makes the voltage distortion. The 3-phase unbalanced load of EAF causes negative sequence component and reduces the power factor etc.

Major SVC Advantageous in Steel Making Plants

SVC in Steel Making industries can,

  • Increase power factor, which decrease losses of electric network and cost of production and increases productivity.
  • Reduce the reactive impulse to the network which avoids the pressure drop, voltage fluctuation and flicker of network, even reduce malfunction or shutdown of the driving and protection device.
  • Reduce high Order Harmonics Current which decreases network voltage distortion.
  • Reduce Three-phase unbalance of network and negative sequence current, which avoid the oscillation of electric engine rotor.
