This paper analyzes the cable laying method and the process of determining height of semi underground cable layer in the Wentao 220 kV substation in Suqian.By optimizing functional zoning of the semi underground cable layer and layout of the primary and secondary cable suspension brackets,a new semi underground cable layer design scheme that meets the requirements of cable fire zoning,non-dead corner cable layer inspection,and smooth escape routes,is pro-posed.This scheme has been successfully implemented in the Wentao 220 kV substation in Suqian,achieving significant u-tility and is helpful in subsequent implementation of the semi underground cable layer design of 220 kV substation.
