ABB pioneering technologies help Viettel Group to achieve green and inno- vative asset objectives for its headquarter. 

ABB’s supplied technologies include Medium Voltage Switchgear Unisec, Type Tested Low Voltage Switchgear, System Pro E Power, Dry Transformers, ABB i-bus® KNX system and HVAC ACH580 drives.

ABB dry transformer, a high-efficiency solution supports Viettel to minimize environmental contamination and fire hazard for the structures. Manufactured in accordance with international standards, ABB dry transformer is virtually maintenance free. Containing no oil, the transformer is ecological and many of the integral parts are fully recyclable, which fits with the “using clean and renewable materials” motto of Viettel office project.

Meanwhile, the ABB System pro E power, an innovative main distribution switchboard solution, fulfils all elec- trical installation requirements in terms of protection degree, segregation form and electrical characteristics. In addition, the system brings the perfect synergy with all ABB’s low voltage equipment to meet the reliability and efficiency that building’s operators expect.

In order to meet the high demand of safe, smart and connected workplaces for a dynamic and creative work- ing environment, Viettel headquarter is equipped with most innovative solutions for smart building control including the well-established ABB i-bus® KNX system and HVAC ACH580 variable speed drives.

In the innovative ABB i-bus® KNX system, all devices of the building ranging from lighting and shutter control to heating, ventilation, security and energy management communicate with one and another via a single bus interface which is installed alongside the normal power lines. Thanks to the ABB i-bus® KNX system, the Viettel office becomes easier to manage and control delivering increased flexibility, security, economic efficiency and convenience. The operational flexibility of an ABB i-bus® KNX electrical installation allows working routines at Viettel’s office to be adapted easily and comfortably to the needs of the building occupants.

ABB’s ACH580 drives are the next evolution in the speed control of electric motors used for heating, ventila- tion and air conditioning applications. The drives’ HVAC-specific functionality makes the air conditioning pro- cesses more reliable and the environment comfortable. With precise control, the motors only use the energy required to produce the air or liquid flow needed at any given time, so no electricity is wasted. Thanks to the drives’ ultra-low harmonic (ULH) version, excessive electrical disturbances in the grid are avoided to ensure continuous operation. A built-in override mode helps overcome fire emergency in the building, increasing safety of the occupants and property. Integrated BACnet connectivity allowed the drives to easily and cost- efficiently become part of the building automation systems.

“ABB is proud to be a partner of Viettel Group on this innovative building project and to contribute to a greener, safer and smarter operation of their new headquarter. With ABB’s solid track record for smart build- ings in Vietnam, we will continue to help investors achieve their green footprint” said Doan Van Hien, Sales Di- rector, Electrification Business of ABB in Vietnam.

Being functional in late 2019, the building has accommodated Viettel Group’s key business and functions with around a thousand employees. Viettel Group’s ambitious about making its headquarter in Vi- etnam a standard for other Viettel’s buildings over the world.
