Core knowledge of Ground Copper Bus Bar and installation specifications for computer rooms

Ground Copper Bus Bar is the core component of the electrical equipment grounding system, whose core function is to achieve effective connection between electrical equipment and the ground, while also undertaking the function of current transmission and equipment connection in the circuit. This component is made of copper as the core material, and with outstanding advantages such as low resistivity and high bendability, its conductivity is significantly better than that of other material components, such as aluminum bars. As a high-current conductive product, Copper Ground Bus Bar is widely suitable for electrical engineering scenarios such as high and low voltage electrical appliances, switch contacts, distribution equipment, bus ducts, etc. It also has indispensable applications in ultra-high current electrolytic smelting projects, such as metal smelting, electroplating, and chemical caustic soda.

The core standard for judging the quality of Power Distribution Bus Bar is primarily based on copper content. Copper, as a conductive metal second only to gold and silver, directly determines the conductivity of the grounding copper bar due to its purity. In the electrical industry, high-purity oxygen-free grounding copper bars (also known as "purple grounding copper bars") are the best choice, with a purple-red appearance that is clearly distinguished from bright yellow brass. To prevent surface rust and corrosion, some grounding copper bars will undergo tin plating treatment to make their appearance smooth and bright. In high-voltage switchgear, circular grounding copper bars are usually used to avoid the risk of sharp discharge and ensure the safety of operators. Among them, tin-plated circular grounding copper bars have both safety and efficiency, making them an ideal choice for high-voltage scenarios.

Copper Ground Bar has a wide range of applications in power systems. In distribution equipment, due to the superior comprehensive conductivity of copper compared to aluminum, grounding copper bars are commonly used for U, V, W phase busbars and PE busbars in distribution cabinets, and are usually distinguished by phase color letters or phase color paint. Among them, the U phase is painted yellow, the V phase is painted green, the W phase is painted red, and the PE busbar is painted yellow and green alternately.

In a circuit, the connection of high current phase lines, neutral lines, ground lines, and high current primary components inside the electrical cabinet all require the use of a Ground Bus Bar Electrical Panel. For example, the connection between multiple electrical cabinets usually uses a main busbar, and the main busbar branches to the isolating switches, circuit breakers, and other electrical switches of each electrical cabinet as branch busbars. The commonly used grounding copper bars are mainly tin-plated and bare copper bars. At the connection of the copper bars in the electrical cabinet, tin plating treatment, embossing treatment, or conductive paste is usually carried out, and the spare parts are protected by heat-shrink tubing or insulation paint.

In addition to the core applications mentioned above, Grounding Copper Busbar is also widely used in electrical engineering, such as high and low voltage electrical appliances, switch contacts, bus ducts, as well as ultra-high current electrolytic smelting projects, such as metal smelting, electroplating, and chemical caustic soda.

Copper Grounding Busbar has several outstanding characteristics. In terms of corrosion resistance, although copper's corrosion resistance is lower than gold, platinum, silver, and titanium, it is significantly better than metals such as iron, zinc, and magnesium; Compared with aluminum, copper is more resistant to corrosion from non oxidizing acids, alkalis, and seawater, but its corrosion resistance is more advantageous in environments such as atmosphere and weak acids.

In terms of processing and forming, Vertical Copper Bonding Busbar has moderate strength (about 200-360MPa), with deformation resistance greater than aluminum but much lower than steel and titanium, and excellent plasticity. It can withstand various cold and hot pressure processing such as rolling, extrusion, forging, stretching, stamping, bending, etc. The deformation degree of rolling and stretching can reach more than 95%, without the need for intermediate annealing and other heat treatment processes, making it extremely convenient to process.

The Copper Bus Bars for Earthing System Kit also has strong antibacterial properties, which can effectively inhibit the growth of bacteria and other microorganisms. 99% of bacteria in water can be completely killed within 5 hours in a copper environment. This feature makes it unique in scenarios that require high hygiene and safety, such as drinking water transmission, food utensils, and marine engineering.

In terms of welding performance, Grounding Busbar Tmgb Copper is easy to weld through soft soldering, hard soldering, gas shielded arc welding, and other methods, with phosphorus deoxidized copper containing a small amount of phosphorus having better welding performance. Due to the good thermal conductivity of copper, high-power welding facilities and gas protection are required for the welding of grounding copper bars, and spot welding technology is usually not used. In addition, grounding copper bars have good platability and can be electroplated with high melting point metals such as nickel and chromium, as well as low melting point metals such as hot-dip tin and zinc; At the same time, copper bars belong to non-magnetic metals, which play an important role in protecting circuits and avoiding magnetic field interference.
