The fiberglass bridge frame uses sufficiently sturdy materials to ensure the safety of transportation and lifting during installation. When using ropes to lift bus ducts, thick cloth or corrugated paper should be placed under stress to protect the bus ducts from damage. When hoisting bus ducts above 2500A, they should be clamped with sturdy wooden boards and tied with ropes to prevent deformation of the bus duct casing. Before connecting the aluminum alloy bus duct, it is necessary to check whether the contact surface or insulation material is damaged. At the same time, check for any dirt, dust, or other foreign objects, and if so, make sure to clean thoroughly. After connecting a complete circuit, if the insulation resistance is found to be abnormal, it is difficult to check the cause again. Therefore, insulation resistance must be tested for every section of the bus duct connected. When installing according to the layout plan, ensure that the dimensions of each section of the installation line, positioning dimensions, reserved section dimensions, and interface section dimensions meet the requirements of the drawings.
The overall grounding technology of using the shell as the PE busbar for the fiberglass bridge is effective and worthy of promotion. Strong anti-corrosion performance, the aluminum profile shell has much better anti-corrosion performance after anodizing for 10u and galvanizing Long term atmospheric exposure tests on different grades of aluminum alloy sheets and galvanized copper sheets in Japan have shown that the corrosion depth of the former is approximately one twentieth that of the latter, compared to steel shells. A reliable insulation method, with an insulation layer on the conductive busbar and a certain air gap between phases. There is also an insulation pad pressed with DMC material between the conductive busbar and the shell, with triple insulation to ensure the insulation of the bus duct is foolproof, especially when used in humid environments, which shows its superiority.
Large span design, the length of straight busbar trunking is not limited by transportation capacity, and its design and production capacity are not limited by length, which can meet the needs of engineering, especially modern factories, for large-span busbar trunking. Due to its good rigidity, there is no need to install hangers between 6m spans. Easy to install, due to consistent overall dimensions and symmetrical internal structure, it can be arranged as L1, L2, L3, N on either side, making it easy to invert and easy to install.
