The wrapping area of the power angle steel tower is composed of angle irons juxtaposed with each other, and the arrangement direction of the angle irons is perpendicular to the seepage direction. The corners of the angle irons are at the bottom, and the cross-section is in the shape of a "V", and there is a certain grid-gap in the middle of two adjacent angle irons.

A plate of liquid on the power angle steel tower is introduced into the "V"-shaped angle iron according to the downcomer, and the gas can also rise through the grid-gap and form a bag with the liquid to carry out the mass transfer process. The vapor-liquid circulation status in the plate tower and the sieve Plate towers are similar. The gas pressure of the angle iron plate tower is very small, the thermal diffusivity of the high-efficiency liquid phase is very large, the efficiency of the plate tower is very good, the structure is compact, the production and processing are convenient and fast, and the bending strain is very good. However, the efficiency is not as high as that of the sieve tray tower when the processing capacity is small.

What should be done to repair and maintain the electric angle steel tower?

The power angle steel tower is a kind of long-lasting consumable. Why is it a consumable? Because of the characteristics of the iron itself, coupled with the permanent location of the tower pole is more extreme. The consumption and consumption in the middle and late stages are very large, and it needs to be repaired in 20 or 30 years, so it becomes consumable.

Power angle steel towers According to the structural materials of the towers, the towers commonly used in power distribution lines mainly include building steel concrete poles and tower poles. In terms of maintaining structural strength, it is divided into one-piece tower poles and rope tower poles.

There are various structures of towers. Judging from the power distribution lines built in China, towers are often used in power distribution lines with a rated current exceeding 110kV; when the rated current is less than 66kV, building steel concrete is often used for electric poles.

The tower rod stay wire is used to balance the lateral load of the tower rod and the bearing capacity of the power line and reduce the bending distance at the root of the tower rod. The use of the stay wire can reduce the amount of tower rod raw materials and reduce the line engineering budget. On roads in flat terrain, the application of guyed tower poles is very common.

What are the 8 applicable scopes of electric angle steel towers?

1. Corner tower pole J: used at the corner of the line.

2. Intelligent terminal pole D: Built-in front of the distribution station and passing the intelligent terminal.

3. Straight line tower pole Z: It is used for a straight part of the line and hangs vertical suspension insulators.

4. Tension tower pole N: It is used for the very important detailed address of the route, to limit the safety production accidents of the route, and to play the role of the power line of the length of the steel bar lap. It is beneficial to engineering construction and maintenance and is used to hang tension insulator strings.

5. Exceeding the tower pole K: built over a very wide river and scenic spot.

6. Exchange tower pole H: Built on road two for phase inverting.

7. Straight line corner tower ZJ: used for line corner straight line.

8. Bifurcation Tower F: The bifurcation of the double circuit can be used.
