Classification of network transformer level and production realization mode



1、 Classification of network transformers

The classification of network transformer mainly refers to its working temperature range,

As follows:

Commercial grade: 0 ℃ ~ + 70 ℃

Industrial grade: - 40 ℃ ~ + 85 ℃

Automobile grade: - 40 ℃ ~ 125 ℃

Military grade: - 55 ℃ ~ + 125 ℃

It should be noted that military grade is mainly reflected in the limit index, but the power consumption is often higher than commercial and industrial use.

Automotive products are mainly reflected in the safety performance index, which requires a high limit index of products

2、 How to realize different levels of network transformer from production process

From the meaning of network transformer level, it means that the operating temperature range and the performance to adapt to the temperature change are different, but the material, process, power consumption and limit index are different.

In the production of gigabit network transformer products, it is necessary to realize the temperature difference of products at commercial level, industrial level, automobile level and military level,

First of all, it is necessary to distinguish the procurement of various raw materials of network transformer, and ensure the stable characteristics of each material within the temperature range required by its level

Secondly, it is necessary to distinguish the production process

Commercial and industrial devices are produced by basically the same production process and the same production line,

Automobile level and military industry level will adopt different processes and different production lines for production. The key point of production prevention is to ensure its safety and try to reduce the hidden dangers of technology

Third, different test indicators

After the industrial grade products pass the industrial grade index test, they are marked with the industrial grade model for sale as industrial grade products.

Commercial products are tested by commercial level indicators, and then sold with commercial level logo. Industrial products can be sold as commercial products

However, automobile level and military industry level need to pass the specific limit index reliability test, and only after passing the test can they be sold at the corresponding level.
