The hot dip galvanized power transmission pole plays an important role in electrical power transmission and distribution industry. In order to meet the increasingly higher demand for steel tubular pole, our company design and produce many kinds of power transmission pole for the power transmission and distribution system. Besides, our power transmission pole have been tested and approved by the Transmission Pole Tower Testing Station. In addition, our company have become a qualified supplier of SGCC and NGCP.
In order to protect it from weather and corrosion, steel tubular poles are hot dip galvanized in accordance with ASTM 123 and the zinc coating at least 86 microns which could protect steel tubular poles from corrosion as long as 25 years.
Raw Material
When purchasing the raw material (steel plate), on sheet of mill certificate from mill factory must be enclosed. When the raw material arrives at the warehouse, the quality department must take the elongation test and the chemical composition analysis to make sure the raw material have meet all the standard that the needed before production.
Cutting
Cutting the raw material that have meet all the standard required into different length and width. CNC laser cutting is used to direct the material or the laser beam generated. A typical commercial laser for cutting materials would involve a motion control system to follow a CNC or G-code of the pattern to be cut onto the material. The focused laser beam is directed at the material, which then either melts, burns, vaporizes away, or is blown away by a jet of gas, leaving an edge with a high-quality surface finish.
Bending
Forming the cut steel plate into the shape (circular or polygonal or other shape ) that as per specified in the drawing. This invention relates to forming devices and more particularly to devices or machines for bending longitudinally rolled sections or strips of metal stock to desired curvilinear shapes.
Welding
After molding, weld the steel plate together. Usually it is longitudinal welds. It adopts A.C.inverter control, with functions of stable running and fast traveling speed; The seam-tracking arc-guide mechanism is three-spindle system to guarantee the alignment without aberrancy; The main frame and welding machine are intergrated control, with flux auto-recovering system and it is easy to operate with high efficiency.
Galvanization
All poles internally and externally are to be hot-dip galvanized in accordance with requirement mentioned in the relevant drawing or specification
Galvanization standard:IS2629-1985 ,BS729-1971
JSHG has passed the ISO9001 quality management system. Besides,it processes professional physical and chemical inspection lab and is equipped with X-ray detection system, ultrasonic detection system, screen display universal testing machine, photoelectric emission spectrum analyzer, as well as carbon and sulfur microcomputer analyzer etc.
