Sumitomo Electric Industries (SEI) offers technologies for energy transmission (overhead conductors and cables) as well as monitoring systems powered by sensors, digital technology and AI. For overhead lines, SEI offers high temperature low sag (HTLS) conductors for higher operating temperatures with low sag. For existing overhead lines, the transmission capacity of existing overhead line systems can be optimally increased by applying dynamic line monitoring (DLR). 

Technologies from SEI for DLR, such as a DLR sensor, weather sensor and integrator, contribute to the up-rating of the allowable transmission capacity by analysing conductor temperature, transmission current, wind speed, ambient temperature and solar radiation.

SEI presents a portfolio of monitoring systems for cable systems and tunnel systems. These systems are used to reliably evaluate the relevant operating states (inner conductor temperature, operating current, etc.) that enable optimal system operation. With the monitoring system, accidents can be avoided and the efficiency of maintenance can be increased. In addition to the conventional method of data communication (optical and wireless), SEI also offers a specialised method for powerline communication (PLC). Especially for cable systems, SEI offers a wide portfolio of monitoring solutions for partial discharge detection, as well as a variety of detection systems based on optical measurement methods.

GridCal provides grid operators with smart, scalable solutions for digital low-voltage grid management. Their core offering – the GridCal System – is a unique hybrid architecture combining intelligent edge-computing (GridCal Nodes) for substations and a central platform (GridCal Operator) for orchestration and scalability.

This approach delivers local intelligence in the field and central control at scale. Edge devices collect and analyze grid data in real time, enabling fast, autonomous decisions. The central platform ensures network-wide coordination, data visualization, and seamless integration into existing IT/OT infrastructure.

Built on Security-by-Design and full data ownership, GridCal enables reliable, transparent, and cost-efficient grid operations – essential as distributed generation, e-mobility, and heat pumps increase network complexity.

The GridCal solution includes real-time monitoring, automated connection checks, power flow analysis, and AI-based forecasting – all designed for lean deployment and quick results. Through the GridCal Alliance, they also offer a full-service ecosystem of technology, implementation, and support – helping DSOs scale fast, stay flexible, and gain full grid visibility from day one.

The transformation of the energy infrastructure requires a dynamic interplay of various flexibility mechanisms to balance grid stability, economic efficiency and regulatory requirements. Only through the coordinated control of generation, consumption and storage in real time can grid stability, economic efficiency and regulatory requirements be combined.

The VGT Platform serves as the backbone of this strategy, providing precise control over decentralised generation, consumption units and storage systems to optimise the use of flexibility. The VGT Device Manager connects these units in real time, analyses consumption and feed-in profiles – and adapts their use to current market conditions. In this way, flexibility is always used where it brings the greatest technical and economic benefits and grid bottlenecks are avoided.

Thanks to deep integration into IT systems such as ERP, MDM and EDM – as well as direct connection to grid operators and markets – the platform automates the entire energy management process. Decisions are made based on current data and in real time.

Utilising flexibility requires a strategy that goes beyond isolated solutions. The key is a comprehensive system that links existing potential, recognises market opportunities and reacts to grid requirements in real time. Those who implement this integrated control approach at an early stage not only ensure grid stability and security of supply, but also gain considerable economic advantages.

Power Transmission & Distribution Technology Expo 2025 will see Bekaert introduce its high-tensile steel conductor cores (S5A, S7A, S8A), designed for efficient grid upgrades through reconductoring and new line construction. These IEC 63248-compliant cores, coated with corrosion-resistant Bezinal, enable advanced conductors such as ACSS, GAP and ZTACSR to operate safely up to 200°C – increasing current-carrying capacity while maintaining sag within limits.

The benefits are tangible: double the transmission capacity without replacing towers and up to 40% sag reduction with on-site prestressing and seamless compatibility with standard hardware. Field-proven and ready for inspection with magnetic non-destructive tools, cores from Bekaert offer predictable performance and peace of mind.

For new line construction, Bekaert’s high-tensile ACSR conductors combine mechanical strength with low weight and minimal sag – ideal for long spans, harsh weather and lighter tower designs. The result: a leaner infrastructure with a lower total cost of ownership.

Part of the company’s Inhera platform, these solutions reflect its commitment to sustainability, circularity and performance. With these products, Bekaert is helping grid operators shape the way we live and move – safely, smartly and sustainably.

Hivoduct develops, manufactures and installs pressurised air cables for low-loss electrical energy transmission in medium and high-voltage systems. This technology uses pressurised air as an insulating medium, along with a boltless fitting as tube connection. Unlike gas-insulated lines (GIL/GIS), pressurised air cables do not require PFAS gases such as SF₆, making them particularly environmentally friendly and safe. Pressurised air cables can replace high-voltage overhead lines, underground cables and busbars from medium to extra-high-voltage applications efficiently and sustainably.

Pressurised air cables are setting new standards in energy infrastructure for upcoming projects. In particular, they are ideally suited for use in existing tunnels in parallel with other linear infrastructures, thus eliminating or reducing the need for extensive construction work and new tunnels. This approach is particularly beneficial in urban areas, where space is limited and the installation of new overhead lines will face strong opposition. By installing the cables underground in pipes or tunnels with secured access, they are also protected from external weather influences and vandalism, which is key for critical infrastructure.

Hivoduct uses highly conductive aluminium pipes with large conductor cross-sections of up to 5,000mm². At a nominal voltage of 245kV, a single system already allows a power transmission up to 1,600MW and, compared with conventional overhead lines, losses per kilometre are up to five times lower. The product portfolio covers the complete range from medium- to high-voltage (12kV to 420kV) and all current ratings up to 5000A.
