This document is Annex 3 containing technical drawings for electrical substations at Caserma Del Din as part of Work Order HB442895J for the repair of MV SF6 breakers in all electrical substations.

The document provides comprehensive technical specifications and dimensional drawings for five separate switchgear installations operating at 24kV, 630A, and 16kA/1s ratings. The switchgear systems documented include: Switchgear ESS-K with four circuits (SFV Metering, WBC Feeder Line 1, WBC Feeder Line 2, and WBC Incoming DG); Switchgear BLDG #55 CEP with twenty-six circuits (including DRC Incoming, SFV Metering, SDC Bypass, WBS DDI, DRS Risers, SDC Bypass, WBC Ring Feeders, WBC Transformer Feeders, WBS Bus Tie, and DRC Incoming circuits); Switchgear CEP 11 kV with three circuits (SDC Incoming Generator, SFV Metering, and SDC Transformer Feeder); Switchgear ESS-n(S)-n with four circuits (WBC Ring Feeders 1-2 and WBC Transformer Feeders 1-2); Switchgear ESS-S-7 with five circuits (WBC Ring Feeders 1-2 and WBC Line_TR Feeders 1-3); and Switchgear ESS-S-9 with two circuits (DRC Riser and WBC Transformer Feeder). Each switchgear installation includes front view elevations, single-line diagrams showing circuit connections and current ratings, general footprint layouts, and detailed dimensional footprints with precise measurements in millimeters for installation and maintenance purposes.
