Trans Mountain 138kV Transmission Line
Project Description
The Trans Mountain 138kV Transmission Line project in Black Pines, British Columbia is a significant initiative focused on enhancing the power transmission infrastructure to serve the growing energy demands in the region. The project aims to engineer a 723-meter self-supported span across the North Thompson River and design custom 138kV steel structures to ensure an efficient and reliable transmission system.
Results
This project highlights our team’s ability to deliver innovative and precise engineering solutions. By overcoming challenges and ensuring compliance with all standards, we successfully completed our scope of work, contributing to a reliable and efficient transmission system for the region.
Our work on this project underscores our commitment to quality, collaboration, and supporting critical infrastructure development in British Columbia.
Highlights
Engineered a Record-Setting Span: Designed a 723-meter self-supported transmission line crossing over the North Thompson River - the longest span in Primary's history, showcasing innovative engineering expertise.
Custom 138kV Steel Structures: Developed tailored designs for 138kV steel structures, including detailed specifications, shop drawing reviews, and on-site field inspections to ensure quality and compliance.
Innovative Take-Off Structure Design: Created a unique take-off structure to minimize modifications to nearby BC Hydro structures in a difficult-to-access location.
Grounding System Optimization: Conducted a comprehensive grounding analysis to ensure all structures met BC Hydro's strict grounding standards for transmission systems.
Safety Through Induction Analysis: Assessed electromagnetic induction effects on nearby single-phase lines to ensure system reliability and safety.
Ampacity Analysis for Efficiency: Evaluated the electrical capacity (ampacity) of the overhead line to ensure optimal performance under operational conditions.
Compliance with Aviation Standards: Designed marker ball placements that adhered to BC Hydro and Transport Canada requirements for safe aerial navigation.
Precise Crossing Designs: Created detailed crossing drawings that complied with all necessary approval authority specifications, ensuring regulatory alignment.
