How about a dense busbar
Release Time:
Feb 10,2023
Dense busbars use copper or aluminum dense busbars, which have high current density, low resistance, small skin effect, and do not require derating. Low voltage drop means low energy loss, saving users investment. For cables, because the core is made of multiple strands of thin copper wire, its root area is larger than that of dense busbars with the same current rating. Moreover, the “skin effect” is serious, which reduces the rated current, increases the pressure drop, and is easy to generate heat. The line energy loss is large, and it is easy to age.
1. High Density
High-Density BusbarUsing copper or aluminum high-density busbars, the current density is high, the resistance is low, the skin effect is small, and derating is not required. Low voltage drop means low energy loss, saving users' investment. For cables, because the cable core is composed of multiple strands of thin copper wires, its root area is larger than that of high-density busbars with the same current rating. Moreover, the "skin effect" is serious, which reduces the rated current, increases the voltage drop, and is prone to heat generation. The energy loss of the line is large, and it is easy to age.
2. Good Safety
The metal enclosed shell of the high-density busbar can protect the high-density busbar from mechanical damage. The installation of the power distribution system plug-in is safe, the shell can be grounded as a whole, and it is very reliable. However, the PVC shell of the cable is easily damaged by mechanical and animal damage. When installing the cable, cut off the power first. If an error occurs, it will be very dangerous, especially when the cable needs to be grounded on-site, which will increase the risk.
3. Fast Installation
High-density busbars are composed of many parts, and each part is short and light in length. Therefore, only a few people are needed to complete the installation quickly. High-density busbars have many standard parts and inventory, which can be shipped quickly, saving on-site work time. Its compact "sandwich" structure can reduce electrical space, thus freeing up more space for commercial use, such as leasing or as a public space. For cable installation, this is a difficult job. Because a single cable is often very heavy, the installation work requires the cooperation of multiple people, and it takes more time to complete. In addition, due to the bending radius of the cable, more installation space is required.
4. Line Optimization
By using high-density busbars, we can merge some branch circuits and convert them into a large high-density busbar using plug-in boxes. This can simplify the electrical system, obtain more harnesses, and lower current values. Therefore, it saves construction costs and is easy to maintain. For traditional cable lines, cables make the electrical system extremely complex, large, and difficult to maintain, thus wasting engineering costs and installation space.
5. Measurability
For high-density busbars, system expansion can be completed by adding or changing a few sections, and the reuse rate is high. In most cases, cables cannot be reused because the length and route are different. If we want to expand the system, we need to purchase new cables to replace the old ones.
