In the power system, the box-type transformer plays a vital role. However, facing the dazzling array of products on the market, how to choose a box-type transformer that best suits you has become a headache. Here are some things we have sorted out about the things to pay attention to when purchasing a box-type transformer.

What should we pay attention to when purchasing a box-type transformer?

Classification of box-type transformers

Box-type transformers are mainly divided into dry-type transformers and oil-immersed transformers. Dry-type transformers use air or special gas as cooling medium, which has the advantages of fireproof, explosion-proof, and pollution-free. And dry-type transformers are suitable for places with high environmental requirements. Oil-immersed transformers use transformer oil as cooling and insulation medium, which has the advantages of good heat dissipation effect and relatively low cost. And oil-immersed transformers are suitable for outdoor or large-capacity occasions.

Understand the power requirements of box-type transformers

Before purchasing a box-type transformer, you need to first understand your power requirements and select the rated capacity of the transformer according to the power size of the required load and the working environment to ensure that the transformer can work normally and has a certain overload capacity.

Choose the appropriate rated voltage and frequency ‌

Choose the appropriate rated voltage and frequency according to the voltage and frequency of the use environment to ensure that the transformer can meet the voltage fluctuation range and frequency stability requirements of the power grid ‌.

Consider environmental adaptability ‌

Choose a suitable transformer based on factors such as the ambient temperature, humidity, and altitude of the installation site. For example, in an environment with high humidity, a transformer with strong moisture and corrosion resistance needs to be selected; in extreme climates, the high or low temperature resistance of the transformer needs to be considered‌.

‌Brand and manufacturer reputation ‌

Brand and quality are important factors to consider when purchasing a box-type transformer. Well-known brands usually have better quality assurance and after-sales service systems, but the price may be relatively high. When choosing, it is recommended to comprehensively consider factors such as brand awareness, user reputation, product quality, and after-sales service, and choose products with high cost performance.

Installation and maintenance

The installation and maintenance of box-type transformers need to consider factors such as the size, weight, transportation method, and installation environment of the equipment. When selecting, it is necessary to ensure that the equipment can be easily transported to the installation site and meets the installation conditions on site. At the same time, it is also necessary to consider the convenience of equipment maintenance, such as whether it is easy to inspect, clean, and repair.

Energy efficiency and environmental protection

Purchasing transformers with high energy efficiency can not only reduce operating costs, but also help protect the environment. Check the energy efficiency level of the product and whether it meets environmental protection requirements.

When purchasing a box-type transformer, you need to consider multiple factors, including type, power requirements, rated voltage and frequency, brand and manufacturer reputation, installation and maintenance, etc. Through reasonable selection, you can ensure the safe operation and long-term stability of the equipment, and provide strong guarantee for the stable operation of the power system.
