WestConnex - The New M5, Sydney NSW

Background

WestConnex - The New M5, is Australia’s largest transport infrastructure project. WestConnex is part of an integrated transport plan to keep Sydney moving - easing congestion, creating jobs and connecting communities. The new motorway will provide crucial support for Sydney’s long-term economic and population growth.

The Equipment

Ampcontrol was contracted to provide 45 Electrical Equipment Rooms (EERs) to support the power and communications requirements for the WestConnex - M5 tunnelling operations. The EERs include a transformer, switches, circuits and communication systems to assist with fire control, air quality and fan systems. No two EERs are identical as they have different specifications depending on their location within the tunnel. They have been designed and specified to have a 25 year design life.

Unique Application

Westconnex is the first tunnelling project in Australia where EERs have been manufactured offsite and installed directly into the tunnel, compared to the traditional method of building them in-situ. This method has resulted in a number of positive benefits for the project, namely significantly reduced install time, improved safety and a decrease in the resources required for installation.

Achievements

An Australian first for transportable tunnel EERs, manufactured offsite and installed directly into the WestConnex M5 tunnel.

Ampcontrol has provided support during the design phase and once into production, we have achieved all deadlines for delivery. Up to two EERs are manufactured and dispatched from our Hunter operations each week with the last EER planned for delivery in April 2019.

IPM V2- INTEGRATED PROTECTION RELAY

Ampcontrol’s IPM V2 is an intelligent microprocessor based protection relay.

The IPM V2 relay provides all the functions required for protecting electrical outlets supplying underground tunnelling machinery, powered by reeling or trailing cables. The relay can also be used to provide optimum overload protection of motors used on conveyors, pumps, fans and compressors.

Additionally the IPM2 V2 provides pump (snore) and fan (burp) control to protect pump and fan motors.

All of the protection functions are combined into a compact, plug-in unit, which can be easily changed to minimise downtime in the event of a problem with the relay.

Machine data transfer is provided through the use of a Remote Termination Module (RTM) which allows the relay parameters to be automatically uploaded from the machine when a cable is inserted into a power outlet. The RTM also allows for remote start capability.

An automatic insulation test ensures the resistance of the cable insulation to earth exceeds the selected value before allowing the main contactor to close. This is coupled with a manual insulation test to allow fault finding.
