Underground Electrical Distribution Plan for Residential Subdivision

Overview

This civil engineering drawing depicts a comprehensive underground electrical distribution system plan for a residential subdivision called “Villa da Mata” in Franca, SP, Brazil. The plan illustrates the layout of 22 residential lots with associated electrical infrastructure.

Key Infrastructure Components:
– Underground secondary distribution network using PEAD (polyethylene) conduits
– Multiple junction boxes (CS1 and CS2 types) strategically positioned throughout the development
– Distribution panel cabinet (QDP-01 DIN-00) with 250mm occupancy
– Conduit specifications including DPE-(1X2)100-8, DPE-(1X3)100-6, and DPE-(1X1)50-6 varieties

Technical Specifications

– Underground conduit installation depths: 60cm for sidewalks/pedestrian areas, 80cm for vehicle traffic areas
– Junction box dimensions: CS1 (620x620x1000mm), CS2 (520x1070x1000mm)
– Warning tape placement above conduits for excavation safety
– Fine sand bedding requirements for conduit protection

The drawing includes detailed cross-sections showing proper installation methods for secondary conduit lines with specific compaction requirements and safety protocols. Utility corridors are carefully coordinated with the residential lot layout, with seven CS2 junction boxes and one CS1 junction box positioned strategically for network access and maintenance.

The subdivision includes designated areas for institutional use (2,424.51m²), green spaces, and a water detention reservoir, demonstrating integrated infrastructure planning.
