REAL ESTATE DEVELOPMENT
Real estate development mainlyrefers to thepreliminary work of housing construction, whichcanbedivided intotwosituations:
One is the developmentofnew district land,which means transforming agricultural orothernonurbanlandintourbanland suitable for industrial and commercial use, residential housing,commercial housing,and otherurbanpurposes;
The second is the renovation or secondary development of old urban areas, which refers to the demolition of existing buildings and thereconstruction of land that is already urban land due to changes in land use,urban planning,and other reasons,and theinvestmentofnewlabor.

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 of18, 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 capacityx2.
Four layer copperbusbar 9: Current carrying capacity=Singlelayer copper busbar current carrying capacity x2.45 (notrecommended,it is best to use a non-standard busbar instead).
Temperature correction:The current carrying capacity of copper barsat 25~°C isequal tothecurrent carrying capacityat 40~°C multiplied by0.85.
Taking TMY100\*10 copperbar as an example,the specific calculation is asfollows:
1.Singlelayer copper busbar currentcarryingcapacity: 100 \mathsf{mm} widthx18coefficient=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.
