Abstract

The contents of the design are the Electrical Design of NO.3 Building of the first phase of Daxidi. It belongs to the second high - rise residential building, the gross area is 5375 square meters. It has 14 layers on the earth and 2 layers underground,there are 28 households in this buliding.This design contains two parts --strong electric and the weak electric. Strong electric part contains lighting design and the outlet design, lightning protection low-tension distribution system design, and earth connection design; The weak electric part contains cable T.V. systerm design and Fire control system design.

Power supply is the third class load for NO.3 Building of the first phase of Daxidi, As well as to the second class load for Elevator load,The type of radiation with trunk power supply;Light Design includes the calculations of intensity of illumination, the choices of lamps and lanterns, the choice of socket wiring, the way of lying of wires of line branch. This project adopts the earth connection of TN-C-S.. The lightning protection is the third-class for this project. Earth connection and lightning protection use the grounding device together. cable T.V. systerm design and Fire control system design；mainly include the choice and calculation of concerned equipments etc.

The design of electrical accomplished 3128 drawings and one of them is hand-painting Drawing.

Key words: illumination; sockets; cable TV; power distribution ;grounding for lightning
