Fully enclosed and sealed high-voltage tubular bus ductThe integrated structure ensures that no matter what equipment is used in the busbar system, derating is not considered. It has a series of supporting equipment, small size, large capacity, short planning and construction period, easy disassembly and assembly, safe and reliable, and long service life.

1. Loading and unloading of busbar trunking: The busbar trunking shall not be lifted and tied with exposed steel wire ropes, and shall not be stacked or dragged into the air. Do not stop other operations on the shell, use multi-point lifting and forklift to lift steadily, and do not damage the bus duct. Bus ducts should be stacked in dry, clean, and non corrosive gas contaminated warehouses. Flexible packing gaskets should be placed between the top and bottom of the bus duct and properly stored.

2. Route of bus duct equipment: Upon delivery of each batch of bus ducts. All guest rooms are equipped with directional maps and detailed directions. When installing, all bus ducts have corresponding branch lines, partition numbers, and viewing numbers.

3. Before installing the busbar trunking device, check whether the busbar trunking shell is intact or damaged, whether the bolts of the busbar trunking shell are loose, and whether the bolts are firmly connected. Check if the bus duct plug interface can be sealed and locked, measure the insulation resistance with a 500V megohmmeter, and ensure that the resistance value of each section is not less than 20m Ω.

4. Bus duct connection: The bus duct bracket must be sturdy. Bus ducts should be placed correctly according to the part serial number, phase sequence, number, direction, and equipment symbol. When connecting this part, adjacent parts of the busbar channel should be aligned. Bus conductors and enclosures should not be subjected to mechanical stress. The process of connecting equipment: Firstly, check whether the wire connection surface and connector at one end of the bus duct are damaged. After confirming that there is no damage, open the two-level bus duct connecting the busbar, insert the bus duct wire into the connector, and then ensure that it is installed in place and locked with a torque wrench; When connecting the busbar, the ends of the two busway wires that need to be connected should be aligned with each other, and then the copper connector and insulation partition should be inserted into the neutral wire (one copper wire per busbar) and the left and right connectors at the busbar terminal. There are insulation partitions between copper connectors. ）After confirming that there is no damage, insert the insulation bolt and pay attention to the alignment of the copper connector, busbar end, and insulation partition. If the copper connector and insulation partition can be fixed in place, please tighten the bolts. A 500V megohmmeter should be used to check the bus duct at the end of the device. The insulation resistance should be greater than 0.5m Ω. In order to maintain the continuity of the circuit, the double arm bridge should be less than 0.1 Ω. The bias voltage of the 2M section bus duct equipment should be less than 5mm.

5. The height of busbar trunking installation, except for dedicated electrical rooms (distribution rooms, machine rooms, electrical risers, technical floors, etc.), should not be less than 2.2m in the air. When laying busbar trunking, the spacing between support points should not exceed 2.5m (for example, when laying large-span high-strength busbar trunking in the workshop, the spacing can be greater than 6m). When installing busbar trunking on supports and hangers, fixed pressure plates should be used for fixation. The connection point of the bus passage should not be located in the through wall section. When the bus passage equipment passes through the wall hole, no sewage or debris is allowed to enter. The busbar trunking plug and feeding hole (front fork connection) should be located in a safe, secure, and convenient place for equipment protection. When the straight length of the bus duct exceeds 60m, a shortened (expanded) part and a settled (expanded) part shall be set at the expansion joint or settlement joint where the bus duct passes through the building.
