The busway uses copper or aluminum as a conductor, which has a large current capacity and good electrical and mechanical properties. In addition, it uses a metal slot as a housing, so it has no combustion, high safety and reliability, and long service life. Or compare, the area occupied by the equipment is significantly reduced, and the appearance is beautiful, which is very beneficial for the construction and power distribution of large buildings. In summary, the busway has the following characteristics: 1. The current capacity can be large; 2. The voltage drop is small; 3 Strong short-circuit load capacity; 4. High reliability and long service life; 5. High safety; 6. The equipment of the power distribution system can be added or changed freely; 7. Small dimensions; 8. Light weight and easy operation; 9 The connection is very simple (like connecting the water pipeline, the connection is made into a system through joints such as tees, elbows, etc.); 10. Simple construction and inspection; 11. Modern and beautiful
