It has complete quality testing equipment and advanced testing technology. It can complete the production of The inspection of products in each production link can effectively control each link of products from raw materials entering the factory to products leaving the factory.

Transmission line tension tower

According to its shape, it is generally divided into five types: wine cup type, cat head type, upper type, dry type and barrel type. According to its use, it is divided into tension tower, tangent tower, corner tower, transposition tower (transposition tower for conductor phase position), terminal tower and crossing tower. Their structural characteristics are that the tower type belongs to space truss structure, and the poles are mainly composed of single equilateral angle steel or composite angle steel. 

The materials are generally Q235 (A3F) and Q345 (16Mn), The connection between the members is made of rough bolts, which are connected by shearing force. The whole tower is composed of angle steel, connecting steel plates and bolts. Individual components, such as tower feet, are welded into a combination by several steel plates. Therefore, it is convenient for hot galvanizing corrosion, transportation and construction erection. For the tower whose height is less than 60m, a foot nail shall be set on one of the main materials of the tower to facilitate the construction workers to climb the tower.

Transmission line tower structure: the whole tower is mainly composed of three parts: tower head, tower body and tower leg. If it is a guyed tower, the guyed part is also added.
