The thesis includes six Chapters. previous four Chapters are mostly about the design of the forceful electric power Part ； Chapter 5 and 6 are mostly about the design of the light current and firefighting. The part of the forceful electric power mainly including: the distribution system of the low voltage, lighting system and rounding for lightening systematical pose ， among others include load calculation, illumination calculation . The part of the light current mainly including: CATV, Public Broadcasting System, Closed Circuit Monitoring TV and Premises Distribution System and so on. The part of the firefighting mainly including:the design of the warning system and linked system etc. The design adds up to 34 electric charts. Including 17 graphics for the forceful electric power parts ,9 graphics fo
