The nature is different
Busbar: It is a common path on which multiple devices are connected in the form of side-by-side branches.
Busway: It is a closed metal equipment composed of copper and aluminum busbars.
Different uses
Bus: Can be used to transfer data between these computers at will, but only one device can send data at a time.
Busway: It is used to distribute large power to the individual components of the dispersion system. Wires and cables have been increasingly replaced in indoor low-voltage power transmission trunk projects.
The characteristics are different
Busbar: The plug-in bus duct is AC three-phase four-wire or five-wire system, which is suitable for power supply and distribution applications with a frequency of 50-60Hz, an additional current of 100A-6300A, and an additional voltage below 690V, especially for the low-voltage power distribution system of industrial plants and mines and the power supply system of high-rise commercial and residential buildings, hotels, hospitals, etc.
Bus duct: The bus duct is characterized by a series of matching, commercial production, small size, large capacity, short design and construction period, convenient assembly and disassembly, no incineration, safe and reliable, and long service life. The bus duct products are suitable for AC 50Hz, additional voltage 380V, additional current 250A-6300A three-phase four-wire, three-phase five-wire power supply and distribution system engineering.
Turn off the busbar
The closing bus is a bus system composed of metal plates (steel plates or aluminum plates) as protective shells, conductive bars, insulating materials and related accessories.
Including out-of-phase shut-off bus, co-box (including co-phase isolation) shut-off busbar and cable bus, which are widely used in power plants, substations, industrial and civil power supply leads.
Busway
Busway is a closed metal device composed of copper and aluminum busbars, which is used to distribute large power to each component of the dispersion system. Wires and cables have been increasingly replaced in indoor low-voltage power transmission trunk projects. It has been popularized in developed countries abroad, as well as Hong Kong and Macao in China.

The essence of Wiener busbar technology
1. Closed busbar hooking technology
Circuit breakers and contactors can be hooked on the bus through the bus adapter, and fuse switches and other products are directly attached to the bus, so the bus bar plays a two-layer effect of conductive and fixed rotation.

Difference Between Fuse and Circuit Breaker – Vernal
The principle of the fuse is to use the current to flow through the conductor to heat the conductor, and the conductor is ablated after reaching the melting point of the conductor, so the electrical appliances and circuits used for circuit maintenance are not burned out. It is an accumulation of heat, so it is also able to complete overload maintenance. Once...

The advantages of low-voltage closed busbar system without punching connections
1. Save space. The components are attached to the busbar, which can save 1/3 of the size of the box transformer.
2. Operation**. The busbars are placed behind the components, and the upper and lower plates can be sealed to prevent touch protection.
3. Improve the stability and reliability of operation, improve the dynamic and thermal stability, and the bus bar is not perforated.
