IREM Voltage Stabilizers are confirmed as a reliable and cutting-edge solution for the most important civil engineering works, strengthening IREM’s position as an accredited manufacturer of Power Quality equipment.
IREM recently delivered five Sterostab T314AN80HMR voltage stabilizers for the control system of the Storstrøm Bridge cable-stayed bridge currently being completed in Denmark.
Voltage stabilizers are essential to ensure stable and safe operation of critical systems, adapting to complex infrastructures such as this bridge.
The Storstrøm Bridge will extend for approximately 4 km and will consist of two central cable-stayed spans of 320 m in total and 44 other spans of 80 m each, representing a significant engineering work.
What features distinguish the supplied stabilizers?
The 5 three-phase voltage stabilizers manufactured by IREM have the following specifications:
- Mains input voltage: 400V ± 15%;
- Three-phase output voltage: 400V ± 1%;
- Power: 80 kVA;
- Frequency: 50 Hz;
- Correlated phase regulation;
- Degree of protection: IP54 for indoor installation;
- Compliance standards: Marine & Offshore Power Supplies;
- Overload capacity: 120% without time limit;
- Designed to meet the customer’s request for a 30-year operating life.
What advantages do IREM solutions offer?
Voltage stabilizers designed for this infrastructure include a number of advanced features, including:
- Resistance to extreme climatic conditions, including low temperatures and saline atmospheres.
- Mechanical components in painted AISI 316L stainless steel.
- Electrogalvanic treatments to improve the durability of contact surfaces and reduce resistivity.
- Protection of magnetic components through vacuum and pressure impregnation.
- MIL-I-46058C conformal coating for electronic control circuit boards.
- Thermo-hygrometric systems to ensure operation even at -25°C.
- Cables with low emission of corrosive gases and fumes
- External feedback via potential-free status contacts.
What are the fields of application?
IREM voltage stabilizers are essential to power sensitive systems in complex infrastructures such as this latest-generation cable-stayed bridge. In particular, they support:
- The control and supervision systems of the technological systems.
- The real-time data collection through a capillary network of sensors, useful for monitoring movements, vibrations and operating conditions of the bridge.
- The automated inspection equipment, ensuring continuous and reliable operation.
