The main contents include the following aspects: first, the press unit area of law, unit index method for the load calculation. Second, the choice of the box-type stations step-down form and position. Finally, according to the voltage and current choose low voltage cables model calculation and low voltage power distribution equipment. Briefly introduced the lightning protection and grounding of the box-type stations, and map out the relevant electric drawings. Finally based on electrical construction drawing design developed an construction expenditure targets. Keywords: Load calculation; Compact substations; Cable; Grounding; budget  目 录 摘 要........................................................................................................................I Abstract..........................................................................................................II 第一章 设计说明 1.1.住宅小区基本情况.....................................................................................4 1.2.设计范围.....................................................................................................4 1.3.设计原则.............
