WWYK263009_65 Design Analysis_Part22_Part1.pdf

This is an electrical design analysis document containing detailed specifications for underground cable raceway systems, including duct bank data, conduit specifications, and cable data for the Tinker Air Force Base Bomber Agile Common Hangar project. The document includes multiple branch panel schedules and a one-line electrical service diagram.

The analysis shows specifications for three underground raceway systems (RW1, RW2, and RW3) with detailed measurements for duct banks, conduits, and cables. The systems use PVC-40 conduits ranging from 2-4 inches in diameter, with light aggregate fill and specific thermal properties. The branch panel schedules (NH1L, NH1M1, NH1M2, NH1R, NHDR, NL1R1, NL1R2) detail the electrical distribution system, showing circuit descriptions primarily for HVAC and receptacle loads. The system operates on 480Y/277V and 208Y/120V power with varying MCB ratings from 100A to 400A. Temperature limits are set with alarms at 90.0°C and warnings at 88.0°C. The document includes comprehensive ampacity calculations and thermal analysis for all cable runs.
