In daily life, we often see transformers hanging on high utility poles or squatting on the ground in "small houses", both delivering electricity to thousands of households. Which of these two "workers" is more enjoyable?

1. Transformer on power pole (high-altitude operation team)

Why hang it up?   

Small in size, mainly serving residential areas in old urban areas or rural areas with relatively sparse populations

Small capacity, mainly supplying power to residential areas and rural households, with low electricity consumption and low power output

Once the power pole is erected, one can settle down without taking up space on the ground, especially suitable for areas with narrow roads and high land prices

Although it is exposed to wind and rain, it is easy to dissipate heat, has good ventilation at high altitudes, and is naturally cooled.   

2. Transformer on the ground (lying flat on the ground)

Why put it on the ground?   

Big guy, serving new residential areas, large factories, crowded shopping malls, hospitals, etc.

Factories, hospitals, and shopping malls consume a large amount of electricity, and transformers have high power, making them too heavy to be installed. Therefore, large box type substations on the ground must be used!   

There is a dedicated foundation placed on the ground, which is not afraid of wind and rain, and has high safety. The transformer is housed in a box, and the high-voltage electricity is isolated and protected to prevent electric shock and damage.   

Easy to maintain, engineers can inspect at any time, no need to climb high, convenient and safe.   

Whether it's high-altitude or ground-based transformers, they don't have the time to live better than anyone else. They only care about whether the electricity can be safely delivered to the socket, whether the air conditioner is blowing, the computer is on, or the phone can be charged. Essentially, they are all pure oxen and horses.
