In the following cases, the distribution box, cabinet using copper row is more appropriate.

1, when the distribution box, cabinet distribution circuit is too much, the use of copper is more appropriate, mainly to facilitate wiring, because the line is too complex, then, for the wiring is very unfavorable.

2, when the distribution box, cabinet cable in the factory is not convenient to make, the use of copper will reduce the workload, and use more convenient and fast, and more practical.

Extended information

Copper row quality factors affecting the copper row, copper row also become copper busbar.

1, copper busbar surface finish influencing factors

Relative to other metals, copper has good corrosion resistance, but in high temperature, humidity, acid fog and other environments will still undergo chemical changes, resulting in surface discoloration. In the copper busbar production and storage and transportation process, to varying degrees, there are these unfavorable environmental conditions, which will have a certain impact on the surface quality.

2, temperature

In the atmospheric environment, copper at room temperature will be slowly oxidized; the temperature rises to one hundred degrees Celsius, began to generate black copper oxide, oxidation rate is proportional to the logarithm of the time; when the temperature rises to 185 degrees Celsius, the rate of oxidation increased significantly, the temperature rises to more than 400 degrees Celsius, oxidation rate is faster, a parabolic rise.

3, humidity

In a humid environment, due to the presence of water vapor, resulting in copper bus surface corrosion or oxidation. At a certain temperature, the growth rate of the oxide film increases with the humidity.

4, tensile processing process lubricant factors

The role of the process lubricant is to reduce friction, the second is to ensure and improve the surface quality of the processed material, the third is to prevent the metal from sticking welded to the mold, and the fourth is the role of cooling.

Copper busbar stretching process residual lubricant on the surface of the copper busbar, residual acid, residual water, etc. will also directly or indirectly affect the surface quality of the copper busbar. Better lubricant, its lubrication, capacity residue on the surface of the copper busbar is the surface of the copper busbar to produce discoloration or corrosion stains of the root cause.
