Noise Cut Transformer NCT-K

It is equipped with strict lightning protection and surge prevention.

The lightning surge that intrudes into the power line and reaches one coil of the lightning protection transformer first attempts to transfer electrostatically (through capacitive coupling) to the other coil. However, if the transformer has a shielding plate, this can be effectively prevented. Following that, a slower electromagnetic transfer (through inductive coupling) occurs, and there has been no lightning protection transformer equipped with a structure to prevent this; they have relied on added capacitors and varistors, which have been insufficient to protect low-resistance information devices and precision electronic equipment. However, a structure like the "Noise Cut Transformer" that prevents high-frequency magnetic flux from the lightning surge from crossing to the secondary side can also prevent this electromagnetic transfer. The NCT-K type takes advantage of this characteristic, featuring high voltage insulation that withstands the impact of lightning surges, excellent shielding with a very low impedance triple structure, and is designed and manufactured to easily divert powerful lightning surges to the ground, almost completely preventing them from escaping to the load side, making it a "Noise Cut Transformer for lightning protection."
