Factory training and learning

As a member of ZTelecgroup, we participated in a special training organized by the company yesterday – to the factory for on-site learning. Our factory has a good reputation in the field of transformer production. Its advanced production technology and strict quality control system are well-known in the industry. This training is of great significance to us. It aims to give us a deep understanding of the product production process, strengthen cooperation with the factory, and improve our professional quality and business capabilities so that we can better serve customers in future work.

After a few hours of driving, we finally arrived at the factory. The factory gate is solemn and eye-catching, and the sign at the door clearly shows the name of the factory and the production field. Under the guidance of the staff, we entered the spacious and bright production workshop, where the transformer was born. And each process embodies the crystallization of technology and craftsmanship.

1. Raw material area

The first thing is the raw material area, where various key materials for making transformers are stored. Silicon steel sheets are neatly stacked, and they are the main material of the transformer core. The copper wire next to it has good electrical and thermal conductivity and is the key material for the winding. Copper wires of different specifications have different thicknesses and uses. The staff introduced that when choosing copper wires, we should pay attention to its cross-sectional area, current carrying capacity and other parameters to ensure that it meets the design requirements of the transformer. These seemingly ordinary raw materials are actually the basis for determining the quality and performance of the transformer. Their characteristics and quality affect the final performance of the transformer from the source.

2. Iron core manufacturing area

Walking into the iron core manufacturing area, workers are busy in an orderly manner. The staff picked up a piece of silicon steel sheet to show us, explaining that each piece of silicon steel sheet must undergo strict testing to ensure that its thickness is uniform and the surface is flawless. In this area, advanced equipment and precise technology cooperate with each other to ensure the high-quality production of the iron core. The excellent performance of the iron core provides a solid support for the stable operation of the transformer. It is like a human skeleton, supporting the operating structure of the entire transformer.

3. Winding production area

In the winding production area, the humming sound of machines is endless, and workers are skillfully operating the winding equipment. When winding, the number of turns and winding direction of the wire must be accurately controlled according to the design requirements of the transformer to ensure that the inductance and resistance of the winding meet the standards. The winding production process is directly related to the electrical performance and reliability of the transformer and is a key link in the entire production process.

4. Assembly area

Finally, we come to the assembly area, where all the components of the transformer are gathered and where the birth of a complete transformer is witnessed. The staff will assemble the prepared body, lead wires, insulation parts and other parts according to strict process requirements.

Technical Exchange

After the on-site learning in the factory workshop, we had the honor to have an in-depth exchange with the factory’s senior technicians Mr. Huang and Mr. Ma. Mr. Huang has many years of work experience in the field of transformers, and his explanation gave us a deeper understanding of transformers. For example, we have a more thorough understanding of the classification of transformers and iron cores, and a clearer understanding of the relationship between the number of turns, voltage, current, capacity and other values in the transformer. Then, Mr. Ma explained to us the knowledge of switchgears and box-type transformers. For example, the composition and working principle of box-type transformers, the difference between American box-type transformers and European box-type transformers, etc.

Mr. Huang also introduced us to the new technologies and processes used in transformer production. “We have made a new breakthrough in energy-saving technology, using amorphous alloy materials to make iron cores,” said Mr. Huang. “This material can effectively reduce electromagnetic losses, and has a more significant energy-saving effect than transformers with traditional silicon steel cores. Moreover, we are constantly optimizing the design to reduce the no-load loss and load loss of the transformer and improve energy efficiency.”

This visit and study gave us a comprehensive understanding of transformers. From the characteristics of raw materials to the fine production process and the application of new technologies, every link impressed me. We not only mastered some knowledge about transformers, but also had a clearer understanding of the development trend of the industry.

When communicating with customers, we can answer their questions about transformers more professionally and confidently, and provide customers with more accurate product recommendations. When processing orders, we can also better coordinate with the factory according to customer needs to ensure product quality and delivery time.

This visit and study not only improved our professional ability, but also made us full of confidence in future work. I believe that as long as we continue to learn and improve ourselves, we can achieve better results in our work.
