Leading motor, drive and gearbox manufacturer WEG will play a key role in a major water transmission project in the Middle East, set to be one of the largest of its kind in the region. 

 

WEG will supply a package of motors, variable frequency drives (VFDs) and transformers to support the new project, which aims to deliver water between two of the largest cities in the region.

 

The new water infrastructure will be a major undertaking as it will be one of the largest water transmission systems in the region. The customer required a holistic package of transformers, water-cooled VFDs and motors with powers up to 9.1MW, able to withstand the region’s extreme temperatures and environmental conditions to power pumps in the new system.

 

MVW01 VFDs

The MVW01 VFDs with water cooling, which was a specific requirement for this project, feature an electric panel with a new thermal dissipation design, allowing for a greater range of power output. The MVW01 also features a user-friendly 10” touchscreen HMI that simplifies programming and monitoring of key parameters. The VFD allows for efficient process speed control, reducing energy consumption, operation and maintenance costs and the total cost of ownership (TCO).

 

The phase shifting transformers selected as part of this package offer complete isolation to mitigate common-mode voltage stress on the motor and naturally reduce harmonics on the power supply. Oil-type transformers for outdoor installation were chosen to meet the project requirements. 

 

The transformers’ step-lap-type magnetic core optimises noise levels and low exciting current while the optimised natural anchoring of the set withstands short circuit stresses. In addition, the external coatings protect the transformers against the harshest environments.

 

Water-cooled W60 MV motors

WEG also supplied water-cooled W60 MV motors offering excellent performance across severe and aggressive operating conditions, including the extreme ambient temperatures. These modern motors are designed to meet the requirements of industrial applications, including compressors, pumps and fans, and are 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 Alaa 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.”--TradeArabia News Service
