The meaning of a telephone pole
A telephone pole is, as its name implies, a pole of wire. Appearing in every rural-field-road-street, it was one of the important infrastructure in early China. Early poles started with wooden poles, even those with low voltage levels. Later, due to the development of steel and reinforced concrete, as well as technical requirements, these two materials replaced most of the wooden poles, and the suitable wood gradually became scarce, wooden poles were basically hard to see in the city. But in some less developed places to set up telephone lines also use a wooden pole, because the weight of the wooden pole is light, easy to set up, and the load of the telephone line and the tension is small, the wooden pole can be competent, the telephone line if there is a change, move the pole is also convenient. So, there are some wooden telephone poles.
