Since the busbar is made of copper or aluminum as the conductor, the current capacity is large and the electrical and mechanical properties are good. In addition, the metal groove is used as the outer shell, so it has the advantages of non-burning, high safety and reliability, and long service life. In comparison, 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. To sum up, the busbar has the following characteristics: 1. The current capacity can be large; 2. The voltage drop is very 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 size; 8. Light weight and easy operation; 9. The connection is very simple (just like connecting water pipes, each section is connected into a system through joints such as tee and elbow) as shown in the figure below; 10. Simple construction and inspection; 11. It has a modern appearance.
Low-voltage busbar use
FM series busway is based on the professional technology of the United States and Japan. It is suitable for three-phase three-wire, three-phase four-wire and three-phase with rated working voltage of 660V and below, frequency of 50Hz (or variable capacity section 60Hz), and rated current from 60A to 5000A. The power supply and distribution system in the five-wire series has the advantages of small size, large transmission current, safe and reliable, flexible installation, non-interference between power distribution construction and infrastructure construction, reasonable design, and complete specifications. FM series low-voltage busway is a modern The most ideal power supply equipment for large and medium-sized enterprises, high-rise buildings, introduction projects, experimental bases and other places.
Normal working conditions
1. Continuous work indoors.
2. The ambient air temperature is not higher than 40°C, and the lower temperature limit is -10°C.
3. The relative humidity should not exceed 90% (when the ambient air temperature is +20°C).
4. When the working conditions have special requirements, our factory can manufacture them according to the special requirements.
The main technical parameters
Rated voltage: 660V.
Rated frequency 50Hz (or 60Hz).
Insulation resistance value: The insulation resistance of each busway unit should be greater than or equal to 20 megohms. When installing, the user should check the insulation resistance value before installation.
Dielectric strength, each section of busway unit has been subjected to 50Hz3750V/Min power frequency withstand voltage test before leaving the factory.
Short-circuit strength (ability to carry short-circuit strength): The busway can withstand the thermal stress and electromotive force generated by the short-time withstand current and rated peak withstand current specified in Table 2.
