About this file
This file is a PLS-CADD drawing (Section 11-J Plans) prepared for the City of Gallup, New Mexico by T & D Services, LLC, depicting the design of a 115 kV transmission line for the New Sunshine Substation project. The plan shows a transmission line route with multiple tower locations and configurations, including existing towers to be replaced and new towers to be installed. The project involves eight primary transmission structures: an existing T8-N tower at station 0+000 to be maintained, a T7-N tower to be replaced with a new T7-NA configuration at station 0+857, a new T6-NA tower at station 0+951, a retiring T6-N tower at station 1+180, a new T6-N tower at station 1+449, a T5-N tower to be replaced at station 1+849, and an existing T4-N tower at station 2+257. The drawing includes detailed specifications for two H-Frame Steel structures and provides cable tension calculations for both 3/8-inch 7-strand EHS steel and Cardinal ACSR conductors at various line segments, with initial tensions ranging from 182 to 3,681 pounds at 60 degrees Fahrenheit.
The drawing was prepared for preliminary design review with revisions dated January 30, 2025, and indicates design completion as of September 10, 2025. The project site encompasses approximately 4.375 acres and includes property boundary information, utility easements, and infrastructure details such as concrete walls, wire fencing, and chain-link fencing. Geographic coordinates and elevation data are provided for each tower location, with embedment lengths ranging from 8 to 16 feet and tower heights between 52 and 92.5 feet. Maintenance specifications require the existing T7-N to T8-N line tensions to be maintained and mandate epoxy coating application to a minimum of 1 foot above ground line for all direct embedment poles. The drawing serves as the technical design foundation for the transmission line construction contract in Gallup, New Mexico.
