早期的各種電線桿，都是從木桿起步的，甚至包括電壓等級不是太高的高壓線電桿。
In the early days, all kinds of poles started from wooden poles, even including high voltage poles whose voltage level was not too high.
后來由于鋼筋和混凝土的發(fā)展，結(jié)合技術(shù)上的探究，運(yùn)用離心力的原理制造，鋼筋混凝土錐形水泥桿、等徑水泥電線桿代替了大部分木桿，水泥電桿堅固耐用、耐腐蝕、耐溫差、高強(qiáng)度、抗裂。
Later, due to the development of steel bar and concrete, combined with technical research, using the principle of centrifugal force to manufacture, reinforced concrete conical cement pole, equal diameter cement wire pole replaced most of the wood pole, cement pole is durable, corrosion resistant, temperature difference resistant, high strength, crack resistance.

而且適用的木材逐步稀缺，水泥電線桿外觀光滑美觀，更便于城市美化，城市里面就基本上難見木桿了。
And suitable timber is gradually scarce, cement poles have smooth and beautiful appearance, more convenient to beautify the city, and wood poles are basically hard to see in the city.

But in some less developed areas, wooden poles are also used to erect telephone lines because they are light in weight and easy to erect, and the load and tension of telephone lines are small. The wooden poles can be competent. If the telephone lines are changed, it is also convenient to move the poles. So there are some wooden telephone poles.
