35kv single circuit tension transmission pole
The tension transmission pole is mainly subjected to longitudinal tension and controls the range of the pole. Tension bars generally refer to linear tension bars, and corner bars refer to the line on the tower to change direction, that is, they are all towers to withstand wire tension, the difference is that the corners of the bar to withstand the force is not on the same axis. Linear pole is the most basic pole in the whole line to support the line, in the straight line without turning, tension pole is used at the end of the line or turning place, will be used in the middle of a long line. From the appearance, the tensile pole conductor has an open breaking point, and the two section is connected by a drainage line. Tension pole is mainly to straighten the cable position, the cable can not be too tight nor too loose, tension pole is playing such a role, tension pole is generally equipped with a cable to fix.
Seen from the appearance, there is no breaking point for the straight pole conductor, and there is breaking point for the tension pole conductor. The two sections are connected by the drainage line. A straight pole usually has no pull wires, and a tensile pole must have a pull wire. A straight pole usually uses a common pole, and a tensioning pole usually uses a reinforced pole.
From the material point of view, most of the linear poles use needle insulators, tension poles use suspension coils and use tension clamps.

Why choose our transmission pole?
Our electric steel rods are treated with hot dip galvanized or hot spray zinc coating for corrosion protection, which can have good anti-corrosion and corrosion effects.
Our electric power line quotations are very reasonable, there will be no higher than other manufacturers’ sights, and the budget of operators and constructors can be well guaranteed. It is the first choice for many large units and municipal power agencies. At the same time, the quality of our products is better guaranteed.Transmission Pole manufacturers
