IFB_25-040-MC_Addendum_1_ATTACHMENT__B_.pdf

This document is an Invitation for Bid (IFB) 25-040-MC for 69 KV Vertical Air Break Replacement Disconnects, involving multiple electrical substations including Marydia Substation and BVL Substation. The project involves replacing vertical air break disconnects at various substations, with detailed technical drawings and site photographs provided in Addendum 1, Attachment "B". The technical specifications include precise dimensional layouts, electrical connection details, and mounting configurations for disconnect switches at different locations, with specific measurements and component numbering for each site.

The technical drawings demonstrate complex electrical infrastructure configurations, showing multiple disconnects, conductor connections, and structural support details across different substation sites. The images include both schematic diagrams and actual photographs of the electrical equipment, revealing galvanized steel structures, white electrical cabinets, insulator assemblies, and gravel-lined substation grounds. The documentation appears to be part of a comprehensive replacement and upgrade project for high-voltage electrical infrastructure, with precise engineering specifications to ensure proper installation and performance of the new disconnect switches.
