HV Substations Minto Ingleburn and Guildford
Degnan successfully delivered three traction substations at Minto, Ingleburn, and Guildford as part of the Power Supply Upgrade (PSU) for the Rail Network and critical to supporting its capacity and reliability for future operations.
The project scope included constructing robust structures with bored concrete piles, concrete floor systems, and steel structural frameworks.
The façades combined honed and split face blockwork with alucobond composite cladding, while two-stage louvres ensured adequate ventilation for the housed electrical equipment.
Advanced drainage solutions were implemented, including SPEL oil containment and stormwater detention systems, ensuring environmental safety and compliance. Each substation was enclosed by blockwork retaining walls and security fencing, providing a secure and functional design.
Working within a live rail corridor presented challenges requiring meticulous planning and coordination. Degnan prioritised safety and efficiency, leveraging expertise in high-risk rail environments to deliver the project successfully. Collaboration with high-voltage contractors and Sydney Trains, the end user of these traction substations, ensured seamless integration and functionality.
