Leading motor, drive, and gearbox manufacturer WEG is set to play a key role in one of the largest water transmission projects in the Middle East.

WEG will provide a complete package of motors, variable frequency drives (VFDs), and transformers to support the new water infrastructure, which will deliver water between two of the region’s biggest cities.

The large-scale water transmission system presents significant challenges, with extreme temperatures and environmental conditions. The customer required a holistic solution that includes transformers, water-cooled VFDs, and motors with power ratings up to 9.1 MW to power the pumps within the system.

The MVW01 VFDs with water cooling, a specific requirement for this project, are equipped with an electric panel featuring a new thermal dissipation design that allows for greater power output. The VFDs also include a user-friendly 10-inch touchscreen HMI, simplifying programming and monitoring of key operational parameters. By controlling the process speed efficiently, the VFDs reduce energy consumption, operation and maintenance costs, and the overall total cost of ownership (TCO).

The phase-shifting transformers in the package offer complete isolation, reducing common-mode voltage stress on the motor and lowering harmonics on the power supply. Oil-type transformers were selected to meet the project’s outdoor installation needs. Designed with a step-lap-type magnetic core, the transformers optimise noise levels and keep exciting current low, while their rugged construction can handle short circuit stresses. In addition, the external coatings protect the transformers against harsh environmental conditions.

WEG also provided water-cooled W60 MV motors, which are built to deliver excellent performance under aggressive operating conditions, including extreme ambient temperatures. These motors are designed for industrial applications such as compressors, pumps, and fans. They are both efficient and modular, allowing for different cooling configurations.

“Water transmission systems are a crucial part of critical infrastructure and require specialised equipment that is both robust and reliable to ensure that they run effectively and safely. This can be a particular challenge in harsh outdoor environments,” said Alla Aldrras, HVS development sales manager for HVS Motors & Drives. “We’ve drawn on our experience of developing solutions for the water industry globally to offer a holistic package to meet the customer’s needs, and thanks to our facilities in Brazil, we are able to deliver this well within the project schedule.”
