Silent Group: Busway Introduction

The Bus-Way-System, a new circuit technology developed in the United States, features conductors made of copper or aluminum, supported by non-flammable insulation, and then mounted in a metal channel to form a novel conductor. Its first practical application in Japan was in Showa 29 (1954), and since then, busbars have seen development. Now, they have become a wiring method for electrical equipment and power systems in high-rise buildings and factories.

In recent years, due to the increasing demand for electricity in buildings, factories, and other structures, the traditional conduit wiring method has posed numerous difficulties during construction. Moreover, when it comes to modifying the power distribution system, simplifying the process is nearly impossible. However, by using busbars, the goal can be easily achieved, and the buildings can also be made more aesthetically pleasing.

From an economic standpoint, busway slots are more expensive than cables, but compared to the various accessories for wiring and the entire power system, using busways can significantly reduce construction costs (see simplified diagram), particularly when dealing with high current capacities.

Busbar channel advantages:

Due to the use of copper or aluminum as conductive materials in busbars, they offer high current capacity and excellent electrical and mechanical properties. Additionally, being encased in a metallic shell, they are non-combustible, highly reliable, and have a long service life. Compared to traditional power distribution equipment, the busbars significantly reduce the occupied space and have an aesthetically pleasing appearance. They are highly beneficial for the construction and power distribution in large buildings. In summary, busbars possess the following characteristics:

1. The current capacity can be quite large.

2. Voltage drop is minimal.

3. Strong short-circuit load capacity.

High reliability and long service life.

Highly secure;

6. Equipment additions or modifications to the power distribution system are flexible and unrestricted.

7. Compact in size and dimensions.

8. Lightweight and easy to operate;

9. The connection is extremely simple (just like connecting water pipes, joining sections through tees, elbows, and other fittings to form a system), as shown in the following diagram.

Construction and inspection are simple.

11. Modern aesthetics.
