The service life of transformers in Southeast Asia is usually 15-20 years, but it can be shortened to 5-8 years due to harsh environments (high humidity, salt spray, extreme weather) and improper use. This article sorts out all key factors affecting transformer service life, helping users avoid mistakes and extend equipment service life.
The core influencing factors are divided into four categories: environmental factors, installation factors, operation and maintenance factors, and product quality factors. Among them, environmental factors (high humidity, salt spray) and improper O&M are the main reasons for the shortened service life of transformers in Southeast Asia, accounting for 70% of failure cases.
The following table details each influencing factor, specific impacts and improvement measures, which is easy to understand and operate:
| Influencing Factor Category | Specific Factors | Impact on Service Life | Improvement Measures |
|---|---|---|---|
| Environmental Factors | High humidity, salt spray, high temperature | Insulation aging, tank corrosion, internal short circuit | Install desiccant breathers, do anti-corrosion coating, keep ventilation |
| Installation Factors | Unlevel foundation, poor sealing, improper grounding | Equipment vibration, moisture ingress, surge damage | Level foundation, strengthen sealing, standardize grounding |
| O&M Factors | Irregular inspection, delayed spare parts replacement | Hidden dangers accumulate, small faults become major failures | Form regular inspection habits, replace spare parts in time |
| Product Quality Factors | Inferior materials, unqualified manufacturing | Early failure, short service life | Choose qualified products from regular manufacturers |
