With the development of China's power industry, the increase of overhead lines and long-distance transmission lines, the capacity of the capacitor charging power increases when the line is unloaded and lightly loaded, resulting in increased power frequency over-voltage and over-voltage operation. This phenomenon has been Appeared in most areas.
In the power system, shunt reactors are used to compensate line capacity charging power, reduce line losses and increase power factor, weaken the long-term load-bearing effect of no-load or light-load, and stabilize the system voltage.

1) BKSC type dry iron core reactor adopts dry core structure, three-phase common body, core adopts high quality silicon steel sheet, iron core column is composed of multiple air gaps evenly distributed, and air gap adopts epoxy glass cloth plate as filling material. The gap does not change during long-term operation.
2) The dry iron core reactor has a simple overall structure, small size, light weight, reasonable layout, and easy installation. It is an ideal supporting equipment used in the indoor capacitance compensation frame and cabinet type equipment, and has no electromagnetic pollution, no oil pollution, Good flame retardancy, less magnetic flux leakage, and less electromagnetic interference to the environment.
3) The coil is epoxy cast type. Epoxy glass mesh cloth is applied inside and outside the coil for reinforcement. The epoxy casting system is cast under vacuum state. It has excellent heat dissipation performance, good insulation performance, high mechanical strength, and dynamic thermal stability. Well, no cracking occurs.
4) Epoxy casting coils do not absorb water, have low partial discharges and can operate safely under harsh environmental conditions.
5) The gap between the stem and the insulating cylinder is sealed with epoxy resin, and the upper iron yoke and the coil are tensioned by the pull screw, so that the iron core and the coil are integrated, and the insulation strength between the iron core and the coil is strengthened. Reactor operation noise is reduced.
6) Special insulation components are installed on the coils and cores, cores and ground to ensure the electrical insulation distance.
7) The reactor iron core and windings are not immersed in any liquid. The cooling method is air self-cooling, no oil leakage, easy to manufacture and maintain, and easy to operate.
8) Use special computer software for auxiliary optimization design. The inductance value is accurate and there is a reasonable margin for temperature rise.
Products are widely used in power systems, chemicals, metallurgy, coal mines, electrified railways and other special occasions.
