INDUSTRIAL MANUFACTURING
Industrial manufacturing refers to the industry in the era of mechanical industry that utilizes certain resources (materials, energy, equipment, tools, capital, technology, information, and manpower, etc.) to transform them into large-scale tools, industrial products, and consumer goods that can be used and utilized by people through the manufacturing process in accordance with market requirements. The manufacturing industry is the mainstay of the national economy, the foundation of building a country, the tool for revitalizing the country, and the basis of a strong nation.

PUBLIC BUILDINGS
Public buildings include office buildings (including office buildings, government department offices, etc.), commercial buildings (such as shopping malls, financial buildings, etc.), tourist buildings (such as hotels, entertainment venues, etc.), science, education, cultural and health buildings (including cultural, educational, scientific research, medical, health, sports buildings, etc.), communication buildings (such as postal, telecommunications, data centers, broadcasting rooms), transportation buildings (such as airports, high-speed railway stations, train stations, subways, bus stations, refrigerated warehouses, etc.), and others (police stations warehouses, detention centers, etc.).
REAL ESTATE DEVELOPMENT
Real estate development mainly refers to the preliminary work of housing construction, which can be divided into two situations:
One is the development of new district land, which means transforming agricultural or other non urban land into urban land suitable for industrial and commercial use, residential housing, commercial housing, and other urban purposes;
The second is the renovation or secondary development of old urban areas, which refers to the demolition of existing buildings and the reconstruction of land that is already urban land due to changes in land use, urban planning, and other reasons, and the investment of new labor.

The calculation method of copper busbar current carrying capacity mainly includes the following steps:
Basic formula: Copper busbar current carrying capacity at 40 ℃=busbar width 9x thickness coefficient 9. The thickness coefficient varies depending on the thickness of the copper bar, for example, a 12mm thick copper bar has a coefficient of 20, a 10mm thick copper bar has a coefficient of 18, and so on.
Double layer copper busbar 9: Current carrying capacity=Single layer copper busbar current carrying capacity x1.56-1.58.
Three layer copper busbar 9: Current carrying capacity=Single layer copper busbar current carrying capacity x2.
Four layer copper busbar 9: Current carrying capacity=Single layer copper busbar current carrying capacity x2.45 (not recommended, it is best to use a non-standard busbar instead).
Temperature correction: The current carrying capacity of copper bars at 25 C is equal to the current carrying capacity at 40 C multiplied by 0.85.
Specific calculation example
Taking TMY100 \* 10 copper bar as an example, the specific calculation is as follows:
1. Single layer copper busbar current carrying capacity: 100mm width x 18 coefficient=1800A.
2. Double layer copper busbar current carrying capacity: 1800Ax1.58=2940A.
3. Three layer copper busbar current carrying capacity: 1800Ax2=3720A.
The above calculation results are quite close to the manual data.
