3 PHASE (3UI) LAMINATION CORES

3UI lamination cores are used in the manufacturing of three-phase transformers. In transformers with 3 UI lamination cores, each of the three ei lamination core arms bears a coil body. In contrast to the EI sheets, the 3UI sheets cannot be welded since the joints of the E and I sheets are within the coil body. The E and I sheets therefore have to be nested reciprocally during transformer manufacturing. As a result, either one or multiple identical sheets are slid in from one side of the coil body. Nesting machines are available for the nesting of 3UI sheets, which can significantly reduce manufacturing times.

Interpretation of laminated steel core transformer

图片
  Laminated steel core transformer is a new type of power transformer. It is becoming more and more popular due to its compact structure, remarkable effect and light weight. Laminated steel core transformers add multiple layers of insulating materials to the steel core to improve current transmission efficiency, avoid core AC losses, and reduce noise and vibration. It can also improve the reliability and safety performance of the transformer. The advantages of laminated steel core transformers lie not only in their service life, reliability and efficiency, but also in their environmental protection. They are made of non-toxic, odorless and recyclable materials and have no negative impact on the environment and human body. However, laminated steel core transformers are not suitable for all applications. In terms of application, factors such as the rated capacity of the transformer, operating environment, output voltage, etc. need to be considered to ensure corr

Silicon Steel Laminations: an important role in the power transmission and energy-saving revolution

图片
In the wave of modern technological development, silicon steel laminations are famous for their unique physical properties and wide range of applications. Silicon steel laminations is a special alloy composed of silicon, iron and other elements, which is formed after special treatment. It has low magnetic permeability and high resistivity properties, thus playing a vital role in power transmission and energy-saving applications. First of all, silicon steel laminations play an important role in the field of power transmission. The efficiency and reliability of power transmission systems are directly related to energy supply and economic development. The low magnetic permeability of ferrite silicon steel sheets can effectively reduce eddy current losses in the iron core and improve the efficiency of transformers and motors. In addition, its high resistivity can also reduce Joule heat loss in the iron core, further improving the efficiency of energy conversion. S

High-efficiency and reliable EI Core Transformer: Get to know the EI Core Transformer

图片
  Transformers are an important part of power transmission and conversion, and EI Core Transformer, as a common transformer design, is widely used in various electronic equipment and power systems. It is known in the industry for its high performance and reliability. The design of the EI Core Transformer draws on pictographic symbols, with the shape resembling the letters “E” and “I” combined. This structure consists of two parallel magnetic cores connected by windings. This specific design structure gives EI Core Transformer advantages in energy transfer and magnetic circuit conduction. First of all, EI Core Transformer can achieve high-efficiency energy transfer. Its magnetic core structure provides a shorter magnetic path length, thereby reducing energy loss. In addition, this design can also reduce magnetic leakage loss and improve energy conversion efficiency. Compared with other transformer designs, EI Core Transformer can work more efficiently during the
