Arrester installation should pay attention to the quality of the connector Zhengzhou Lei Electronic Engineering Co., Ltd. technical personnel to remind you: all kinds of lightning protection tower installation should pay attention to the quality of the connector.
The metal components of the lightning arrester must be galvanized and the galvanized layer must be protected during operation. A galvanized steel pipe is used to make the tip. The thickness of the pipe wall must not be less than 3mm, and the tin length of the tip should not be less than 70mm.
The fitting joints of all kinds of components must be qualified after they are qualified for fastening and welding. The pillar bolts, crossbars, diagonal rods, and main beams of the tower must be 100% perforated, and the bolts in the minor part must not exceed 2% of the total number of perforations, but they must be repaired by electric welding. The strength of the weld should be equal to the total bolt strength of the joint. For high-strength bolts, it should be equal to the missing bolt strength.
The column flange is locked with double nuts, and the other bolts are locked with spring washers. The bolt penetration direction should be divergent and reasonable. The exposed length is 2 to 3 threads after tightening. Tighten the flange bolts and tighten them symmetrically according to the angle of rounding. When tightening the bolts, tighten them symmetrically from the center to the edge. Bolts that are subject to tension and power loads must be effectively secured against loosening after tightening.
Quality requirements for the welding of components: During the welding of the iron tower components, the engineer is responsible for ensuring that the welding process is operated by qualified workers. Welding shall not be carried out under any of the following conditions without effective protective equipment: heavy wind (wind speed greater than or equal to 10m/s) in rain or snow; relative humidity greater than or equal to 90%.
All welds at the site shall be inspected and stopped at level 3 welds. The welding consumables shall be replaced with the factory. Wind protection, insulation and degreasing should be performed during welding. Stop rust treatment after passing inspection. After the completion of the tower installation, the measurement and calibration must be stopped. All values ​​must meet the acceptance criteria.
The above is just part of the data compiled by the technicians of Zhengzhou Leidi Electronic Engineering Co., Ltd. For more detailed information, please visit or contact us.
