TUNING CAPACITOR
"DNSC Series Capacitors uses corrugated slitting technology solves the problem of increased losses caused by poor contact between the metallized layer and the metallized film due to film shrinkage. Increases contact area between the metallized layer and film. Under the same unit current-carrying capacity capacitor surge withstand capability is significantly improved. Mainly used in harsh operating conditions with high power system harmonics (THD). Filled with PU resin good heat dissipation and environmental performance

TUNING REACTOR
New Products / New Technology
The windings of the DNSR reactor are wound with Class H‑grade insulated enameled copper wire, arranged tightly and uniformly, with no external insulation layer. This design delivers excellent aesthetics and superior heat dissipation. When the reactor overheats due to grid harmonics, overcurrent, or other factors, this structural design triggers a control signal that trips the switching device, activating overtemperature protection. The reactor is then prevented from being connected to the grid until the ambient temperature drops to an acceptable level, at which point it can resume operation, thereby extending the reactor's service life.
ANTI-HARMONIC INTELLIGENT CAPACITOR COMPENSATION MODULE DEVICE
New Products / New Technology
It has revolutionized the conventional design of reactive power compensation devices, which were typically bulky and cumbersome, endowing the new generation of low-voltage reactive power compensation equipment with superior compensation performance, a more compact footprint, lower power consumption, reduced costs, greater cost‑effectiveness, enhanced operational flexibility, simplified maintenance, extended service life, and improved reliability—thus meeting the increasingly stringent demands of modern power grids for reactive power compensation.
