Load reactor is designed to test frequency inverter.
Features of Three-phase load reactor:
The windings adopt foil winding structure, which has small DC resistance, Strong at short circuit withstand capability and short time overload capability;
The use of composite insulation materials with an insulation level of F or H allows the product to maintain reliable performance under severe working conditions;
Reactor has low magnetic flux density, good linearity, strong overload capability, and low noise;
The iron core adopts low-loss cold-rolled oriented silicon steel, the reactor has low loss, high efficiency and low temperature rise.
