35 Kv Power Transmission Supporting Structure of Substation Bus

Our company produced the tower as per GB/T2694, DL/T646 standards, comply with GB50205, GB/T13912, GB11345, GB3323, GB/T3098.2, GB/T3098.1, GB/T470, and design and production with the latest information on current national standards , and the main products' technical performance in the following areas:

1.The transmission line steel tower and substation framework and other steel structures
Transmission line steel tower with a large load capacity, high strength, support for large span and saving land resources, and the safety and economy of the ordinary compared to the original angle steel tower has a clear technological advantage, has begun a large area application. Material from Q345 steel pipe ~ Q460 steel can be selection.
System using homemade pipe technology: the company now has a large 3200T's double linkage electric hydraulic synchronous CNC bending machine, the machine is controlled to maintain the accuracy within 0.1 mm, can δ ≤ 30 mm, L ≤ 12500 mm sheet metal can arbitrary angle folding system, which manufactures angle error controlled within 0.5 º, full compliance with national standards, through the introduction of complete sets of different diameter pipe mold folding system, to achieve the automation of equal diameter pipe production. Saving the cost of procurement and the procurement cycle to ensure that the production schedule.
Head assembled using self-developed multi-function hydraulic assembly platform sets, assembled and adjusted to ensure that the gap between the head of the longitudinal seam. Gap to stay strictly within the
scope of the process requirements, in conjunction with a comprehensive means test, to ensure that competent longitudinal seam gaps remain qualified. Improve the machining accuracy, reduced rework, saving welding materials and other auxiliary supplies.
High strength steel welding process: analysis by welding of high strength steel, high strength steel welding selected control factors, the research and innovation process parameters, the corresponding process in the development of measures to ensure the welding effect, get a good high strength steel welded joints, improve the high strength steel welding process, broadening the range of products produced, so that the welding capacity and on a new level.


2.Transmission line angle steel tower
Transmission line angle steel tower to provide high-voltage transmission lines to carry the body, is an important part of the grid, provide a guarantee to the level of long-distance transmission grid and a
variety of barriers across the region .
Using the three-dimensional lofting technology, to create three - dimensional entity through lofting software simulation model. Then testing to ensure that each node meets the installation requirements , to improve the tower's maximize performance . After the completion of testing, data generation and processing pipeline and processing of materials. Shorten the time lofting improve the speed and accuracy of processing workshop, improve product quality, saving processing costs.
Using the new bend A flat die. Die according to 0~360 degree angle, improve the bend angle, ensuring the precision of processing, can realize batch production, and improve the processing efficiency. Application of A flat die, improving the processing speed and accuracy, reduce the processing time, save the material consumption, saves the processing cost.


3.Transmission line steel bar
Transmission line steel for city, suburbs and other line covers an area of tension in high voltage transmission lines provide the bearing body, has with its beautiful appearance, covers a small area small and higher strength etc. Service economy features, in urban power supply system has an irreplaceable role.
The main pipe by pressing bending machine to bending, to use vertical sheet improve production efficiency, effectively eliminate the transverse weld, eliminate the hidden danger of quality, improve the strength and degree of safety. The strength of steel grade to GR65 and Q460 level, greatly reduce the consumption of steel, improve material utilization, reduce the production cost.
Using the box type variable cross-section cross arm and tapered tubular variable cross-section. Save material, reduce production cost, increase the appearance, convenient transportation, installation and maintenance.
