Dry-type transformers

Characteristics and uses of dry-type transformers

What is the difference between nph, npf, and nps magnetic cores

Firstly, they are different series of magnetic cores from Platinum, with different optimal usage frequencies. NPF and NPH represent magnetic cores made of iron silicon material, while NPS represents magnetic cores made of iron silicon aluminum material.

Specific classification of materials for transformer cores

The commonly used iron powder core is composed of carbon based iron powder and resin based iron powder. The price is the lowest among the powder cores. The saturation magnetic induction intensity value is around 1.4T;

What are the materials of the magnetic core of the inductor

The most common materials for magnetic cores are ferrite, iron based nanocrystals (with good performance and high price), and silicon steel. Magnetic cores are all magnetic, but the specific residual magnetism after power failure is determined by the coercivity and softness of the iron core.

What's amorphous metal?

Silicon steel sheet iron core is an iron silicon alloy formed by adding a small amount of silicon (usually below 4.5%) to pure iron, which is called silicon steel.

Why do power transformers use silicon steel sheets as iron cores?

The use of silicon steel as the core of a transformer is primarily due to its inherent characteristics: it is a magnetic material with strong magnetic permeability. Therefore, in the current coil, it can generate greater magnetic induction intensity, which can reduce the volume of the transformer.
