Project Spotlight: Plymouth 138/147 Mainstem Replacement

InfraSource has successfully delivered various solutions to the Electric Distribution and Transmission industry, and our team brings over 100 years of combined experience installing underground high voltage transmission lines.

With the completion of this job in Plymouth, Pennsylvania, the crew successfully reduced the likelihood of disruption, leaks, failures and other hazards associated with outdated infrastructure.

Before starting work, the team conducted a thorough inspection of the existing infrastructure to determine its condition and the necessary work. They checked for any potential hazards, existing utilities and environmental concerns that could affect the process.

This project involved the installation of several complex components, including about 10,000 feet of four to five-inch duct package, one manhole, 24, 207-feet of three phase cable, elbow sets, two underground switches and six poles.

The crew used cold splicing to join wires and cable and interruption splicing to join conductors. These required strict adherence to safety protocols due to exposure to high voltages – particularly interruption
splicing, as it is performed while systems are live.

Aerial terminations were performed to connect the overhead lines to the power grid. These had to be Carefully done with safety protocols at the forefront due to the high voltage involved, and the fact they have to be able to withstand wind, rain and ice.

Project Spotlight: 13kV Recloser Installation

Our urban electric crews bring extensive experience and specialized skills to managing projects in densely populated and high-traffic areas. Our team excels in implementing effective and safe traffic management strategies, working collaboratively with local authorities to protect both the crew and the public during project execution. Our commitment to safety and efficiency is evident in every project we undertake, making us a trusted partner in urban infrastructure development.

Because of these capabilities and commitments, we were awarded the contract to replace nine utility poles as part of an extensive infrastructure replacement program. This initiative aimed to enhance the reliability and efficiency of the electrical distribution network.

Throughout the duration of this project, nine utility poles were replaced, along with five 13kV transformers and three additional transformers of varying specifications. Also, 1,500 feet of new 4/0 aluminum conductor was installed, and finally, the existing 1/0 aluminum conductor was replaced.

The new poles and transformers reduce the likelihood of outages and improve overall system reliability. Upgrading the conductor to 4/0 aluminum allowed for higher electrical loads, meeting the growing demand in the area.

In conclusion, our team’s dedication to safety, efficiency, and collaboration has ensured this project’s successful completion and significantly contributed to the enhancement of the local electrical infrastructure. We look forward to continuing our role as a reliable partner in future urban infrastructure projects.
