What are the performance indicators of silicon steel sheets? You will understand after looking at these three points
The core of the transformer is mainly composed of silicon steel sheets. Silicon steel itself is a magnetic material with strong magnetic permeability. In an energized coil,
Detailed explanation of one article: Summary of dry transformer structure and function of each attachment
The dry transformer is an important type of transformer using a relatively common transformer. It is rich in selection and simple structure. It can also be selected attached according to actual needs.
Do dry-type transformers need maintenance?
When introducing dry-type transformers, we will all mention one sentence: Dry-type transformers are maintenance-free transformers. Many people think that dry-type transformers do not require maintenance, and they do not perform maintenance after buying them.

Photovoltaic inverter selection tips
The function of the photovoltaic inverter is to convert the DC power generated by the solar cells into AC power that meets the power quality requirements of the grid. It consists of electronic components (IGBT, capacitors, resistors, reactors, PCB, etc.), structural parts (cabinets, chassis, etc.) and auxiliary materials.
