The busbar and busway are actually one open and one closed, and the other is not closed. The closed busway is referred to as the busway, that is, the busway is sealed
Closing the shell of the busbar, closing the busbar, and busway all refer to the same thing. The metal plate (steel plate or aluminum plate) is a bus system composed of a protective shell, conductive strips, insulation materials and related accessories. It is possible to make a penetrating closed wire with a piercing junction box from a distance, or it can be made into a feed-in closed bus without a junction box in the middle. It is the main busbar, and the bus bar is closed by metal external light.
Closing the busbar has the following advantages:
1. It is easy to standardize and has good interchangeability.
2. Turn off the external light - generally, use non-magnetic or weak data to reduce the occurrence of heat.
3. The bus bar is closed, which improves the anti-fouling ability of the system and is suitable for coal spinning manufacturing. Papermaking, chemical and other areas with serious dust and high humidity. The closed bus can be divided into dense insulated bus and air insulated bus line, suitable for three-phase four-wire system or three-phase five-wire system, rated operating voltage 60v, Q rated operating current 250-2600, frequency 50H, with the advantages of exposed structure, high dielectric strength, large transmission current, good interchangeability, accurate electrical function and convenient operation. It has a series of characteristics such as convenient maintenance and long service life. It is widely used in industrial and mining enterprises, high-rise buildings and public facilities.
Power distribution system connection. The non-closed bus is referred to as the bus, which refers to the connection of voltage distribution devices at all levels in the substation, and the connection between transformers, electrical equipment and corresponding distribution devices is mostly a bare wire or stranded wire of rectangular or circular cross-section.
The busbar is generally used to connect the power distribution cabinets together. Hidden in a combination cabinet for greater security.
Busbar, also known as busbar or current-carrying bank, is a conductor that carries current, and is mainly used for the busbar in switchgear and control equipment, distributing and transmitting power to connect primary equipment.
Modern high-rise buildings and large factories require a lot of electricity, and in the face of such a huge load requiring hundreds of thousands of amperes, it is necessary to select safe and reliable conduction equipment. The busbar system will be the choice of your ambition. The busbar system is an efficient transmission current, and the distribution unit is particularly accustomed to the demand for economically rational wiring in increasingly tall buildings and large factories.
The bus is not installed in the bus duct, if it is installed in the high-voltage cabinet, it only needs to be fixed with a splint with excellent function.

220V DC Hazard in Busbar System – Wiener
The grounding of the DC system should include two conditions: the one-point grounding of the DC system and the two-point grounding of the DC system.
In the DC system, the positive and negative poles of DC are insulated from the ground, and they do not cause any harm when generating a ground current because there is no path to constitute a grounding current, but the ground of one pole is long.
