| This paper investigated the computer aided design for laying the electric cables of the thermal power plant . A technical principle of cables line and cross-section of cable ducts is also presented . Also, the paper puts forwads with the original method about arranging cables in the bridge, and can find the insection of cable. Finally , a computer aided design system for laying electric cables of various thermal power plants (200MW, 300MW, 600MW, etc.) is developed. This system accords with the actual application of power plant cable laying and has been applied in the ppwer plant Sanhe. |
