Structural Features of Wuhan Intensive Busway:

1. Performance

The busbar uses copper or aluminum bars, which have high current density, low resistance, and minimal skin effect, eliminating the need for derating. A small voltage drop means low energy loss, ultimately saving the user's investment. In contrast, for cables, since the cable core consists of multiple strands of thin copper wires, their cross-sectional area is larger than that of a busbar of the same current rating. Moreover, the "skin effect" is severe, reducing the current rating, increasing the voltage drop, and making them prone to heating. This results in significant energy loss in the circuit and makes them susceptible to aging.

2. Safety

The metal enclosed shell of the busway protects the busbar from mechanical damage or animal harm. The use of plug-in units in the power distribution system is very safe, and the shell can be grounded as a whole, ensuring highly reliable grounding. In contrast, the PVC sheath of cables is susceptible to mechanical and animal damage. Installing cables requires cutting off the power first, which can be dangerous if errors occur. Especially when on-site grounding work is required for cables, unreliable grounding increases the risk.

3. Installation

The busbar consists of many segments, each of which is short and lightweight. Therefore, installation can be completed quickly with just a few people. The busbar has many standard parts and is kept in stock, allowing for quick delivery and saving on-site working time. Its compact "sandwich" structure reduces the electrical space, freeing up more room for commercial purposes, such as leasing or public use. Installing cables, on the other hand, is a difficult task. Single cables are often heavy, requiring the cooperation of many people and considerable time to complete the installation. Additionally, due to the bending radius limitations of cables, more installation space is needed.
