Tropical high temperature weather lasts for half a year in most Southeast Asian countries. Under continuous high temperature environment, the heat dissipation capacity of all kinds of electrical equipment will decline significantly. Once encountering peak power consumption and long-term overload operation, it is easy to cause line overheating, component burnout and even electrical fire accidents.
Different from temperate regions, tropical power utilization needs to take the high temperature load limit as the core management index. Factories, construction sites and commercial supporting facilities need to adjust daily power consumption logic to adapt to local high-temperature working conditions. The following table sorts out high-temperature risk points and targeted control measures:
| Equipment Category | High Temperature Core Risk | Safe Operation Standard | Daily Management Suggestion |
|---|---|---|---|
| Distribution Transformer | Coil overheating, oil temperature rise | Control load below 85% of rated power | Regularly clean heat dissipation fins, keep ventilation unobstructed |
| Low-Voltage Distribution Cabinet | Internal dust accumulation leads to poor heat dissipation | Timely dust removal, avoid closed heat accumulation | Install auxiliary heat dissipation equipment in high temperature areas |
| Outdoor Power Cables | Outer skin aging & softening deformation | Avoid direct sunlight exposure, wear protective pipe | Reasonably distribute load to prevent single line overload |
| Temporary Construction Electricity | Mismatched wire gauge for high-power load | Match cable specification according to actual power | Prohibit long-time continuous high-load work |
Formulating targeted high-temperature power utilization rules can effectively reduce seasonal electrical faults and ensure the stable and safe operation of regional power systems throughout the hot season.
