1. Selection Notes
When assessing performance indicators, emphasis is placed on transformer efficiency, temperature rise, insulation standards, and related parameters. These directly mirror the transformer's operational proficiency and steadfastness. Moreover, while adhering to performance criteria, cost-consciousness is key, requiring a balance between equipment costs, transportation expenses, installation fees, and other factors to identify the most financially viable transformer model.
2. Consider the installation environment and conditions
Selecting the Ideal Transformer: Based on the dimensions and configuration of the installation site, determine the suitable transformer model and installation method.
Adapting to Environmental Factors: Take into account the temperature, humidity levels, and altitude of the transformer's installation environment to select a model that can withstand those conditions.
