Ambient temperature is a common cause of small power distribution unit (spdu) failure. In a high temperature environment, the electrical components and cables inside the small power distribution unit (spdu) are prone to failure or damage due to overheating, resulting in electrical failures or fire accidents.

Specifically, a high temperature environment will lead to a decrease in the insulation performance of electrical equipment, which in turn will lead to problems such as leakage and short circuit. In addition, in a high-temperature environment, the electrolyte in electrical components may expand or evaporate, thereby damaging the electrical components and causing circuit failure. In addition, high temperature will also accelerate the aging of the cable insulation, and the cracking and aging of the insulation layer in the cable will also cause circuit failure.

Therefore, in order to ensure the normal operation of the small power distribution unit (spdu), it is necessary to pay attention to the influence of the ambient temperature, select appropriate electrical equipment and cables, and avoid long-term operation in a high-temperature environment. In addition, methods such as ventilation and cooling can be used to reduce the internal temperature of the small power distribution unit (spdu) to ensure the normal operation and life of electrical equipment.
