Transmission Line Steel Pole Introduction

The electric transmission line steel pole has a beautiful appearance. At present, in the wave of building cities and transforming cities, urban construction has higher and higher requirements for power line erection, which is also reflected in the requirements for its aesthetics. In particular, some urban landscape roads have stricter requirements in this respect.

Because of its compact structure and beautiful appearance, the electric transmission line steel pole can basically meet the requirements of aesthetics.

Installation way

The transmission poles below 20 meters are mostly directly buried, 

more than 20 meters, directly buried with flange installation. 

85ft above flange installation.

Power Poles can be classified into:

(1) Linear poles are widely used in flat areas, accounting for more than 80% of the total number of poles. They are mainly used to support wires, insulators, fittings, and other weights. They can bear lateral wind direction.

(2) Crossing pole is a kind of linear rod with tension line. It can not only be used for general linear pole, but also prevent large-scale reversing pole, which is used for less important crossing.

light bearing pole. It is used to prevent conductor breakage after insulator breakdown and is also used for common crossing places. 

(4) the corner bar is used at the corner of the wire rod to bear the resultant force on both sides of the wire.

(5) Tension-resistant poles are usually installed at intervals of about 1 km on a line. They can bear the tension of one side of the conductor and can limit the influence of short-line faults.

(6) the terminal bar is a tensioning pole set at the beginning and end of the line.

branches and cross poles for 10kV and below. From inside to outside, the branches are T-shaped, and the branches are crossed to the sides.
