Retrofitting earthing systems: a breeze with the DEHN earth rod set
Retrofitting earthing systems in existing buildings poses challenges for owners and specialised companies. A functioning earthing system is essential, especially when it comes to renovations, energy modernisations or the installation of photovoltaic systems, wall boxes and heat pumps. However, many existing buildings lack proof of standard-compliant earthing or use outdated systems such as water pipe net-works. In addition, limited space, sealed surfaces and difficulty accessing the soil often make conventional retrofitting a complex and costly undertaking. With the new D18014 earth rod set, DEHN provides a practical solution specially developed for the requirements of renovating existing buildings.To comply with standards, the electrical installation must be equipped with a functional earthing system that safely conducts fault currents to earth, thereby ensuring its safety and functionality. It protects people from hazards, such as lightning exposure, and prevents fires. In Germany, an earthing system is a standard requirement for electrical installations, espe-cially in new buildings. But owners of existing buildings often deliberate on whether retrofit-ting is mandatory when they embark on a renovation or modernisation project.Although there is no general obligation to renew the entire electrical installation in older buildings, newly installed or modified system components, such as technical extensions re-lating to renewable energies, must comply with the applicable safety and technical stand-ards. The relevant standards for the installation of an earthing system are DIN VDE AR-N 4100 and DIN 18014.The D18014 earth rod set from DEHN contains all the necessary components for the profes-sional installation of earth rods and is particularly suitable for new buildings and existing buildings with limited soil or minimal excavation possibilities. Whatever the season, the earth rod solution ensures and maintains stable earth resistance regardless of weather con-ditions or soil moisture. The set meets all relevant standards by complying with the re-quirements of DIN 18014 and the applicable VDE specifications. Its versatility makes it suit-able for a variety of applications, including partial renovations, selective upgrades, installa-tion inside the building or a complete renewal of the earthing system.The set consists of five earth rods, each 1 metre long, to be inserted into the ground. A driv-ing spike makes it easier to drive in the rods. The earth rods are connected to the connecting cable (round wire 8-10 mm or cable 16-50 mm2) without a cable lug using a connection clamp. This establishes a secure connection between the earthing system and the main earthing busbar (MEB) of the electrical installation. For buildings with a foundation area of up to 200 m², two sets are required to meet the normative requirements. Installation in-volves minimal disruption of existing outdoor facilities. Only two small excavation sites and wall bushings are necessary.Technical details can be found here.

Yet more innovation: DEHN opts for new double screw technology for surge protective devices
Long connection cables, which cause inductive voltage drops in switchgear cabinets, often pose a challenge for installers. DEHN solves this problem with an innovative advancement of its proven connection technologies. With the new double screw technology in the Type 2 + 3 surge protective device series DEHNguard MD, the company is once again confirming its pioneering role. This technology complements the existing screw and push-in connection terminal and enables the wiring of different types of conductors. The feed-through wiring option also offers even greater flexibility in terms of electromagnetic compatibility (EMC) for applications with a nominal current of up to 63 A. Push-in technology has proven itself in many areas thanks to its tool-free, fast and secure wiring – especially in residential construction with smaller cross-sections of connection cables. With the new double screw technology, DEHN is now going one step further. Two terminals per pole enable continuous wiring ('V-connection') without additional pin-shaped terminals. The technology allows the use of conductors with a larger cross-section – for two through cables up to 16 mm² each or as a stub line up to 35 mm². This makes it a robust connection that remains permanently stable even under vibration or mechanical stress such as temperature fluctuations.The DEHNguard MD series with double screw technology is particularly advantageous for EMC-compliant wiring in accordance with DIN VDE 0100-534 / IEC 60364-5-53, as there are no high, inductive voltage drops generated across the connection cables. Optional feed-through wiring saves on components and ensures that maximum cable lengths comply with standards. This makes it easier to integrate into existing systems – a huge advantage when retrofitting.The DEHNguard MD has also proven itself in power distribution and switchgear cabinet building, as it meets strict requirements for current-carrying capacity and safety. Areas such as building automation and critical infrastructure also benefit from integrated double screw technology, as it enables durable and low-maintenance connections. In building technology, a supply cable with a cross-section of 16 mm² can now also be easily connected to the device using feed-through wiring.A floating remote signalling contact reliably indicates the status. Defective protection modules in the DEHNguard MD series can be quickly replaced during operation without having to disconnect the wiring.You can find the technical details here.

Hard as steel: The new connection clamp from DEHN
Integrating steel girders, metal sheets, or profiles into lightning protection or equipotential bonding systems often presents a challenge. This is particularly true when protective coatings against corrosion prevent the direct, conductive connection that is essential for effective lightning current discharge or equipotential bonding. The new connection clamp for steel girders from DEHN overcomes this hurdle with a special blade that penetrates coated surfaces up to 0.2 mm without damaging the surface protection. It is therefore particularly suitable for buildings with metallic structures, such as industrial plants, halls, and multi-storey car parks.The clamp is made of high-quality materials and can be used wherever an electrical connection to steel girders, sheets, and profiles is required. With a variable clamping range of 3 to 52 mm, it offers maximum flexibility during installation. The product is approved for use in Zone 2/22 hazardous areas and has a high lightning current carrying capability of up to 100 kA (10/350 μs). It fulfils the requirements of the DIN EN 62561-1 standard and provides a permanently safe, electrically conductive connection even under high loads during a lightning strike.The clamp is available in various designs and materials, both in stainless steel (V2A) and galvanised steel (HDG), with a double clamp or connection bracket. Suitable for round and flat material as well as cables, it is extremely versatile. Typical applications include lightning equipotential bonding with round wire, the installation of air-termination rods without drilling, or the connection of steel girders to earthing systems using connection lugs. The special 7-segment digits also allow use as a test joint, an additional advantage when it comes to testing or maintenance.

Greater manufacturing capacity for European markets: DEHN breaks ground for production in Romania
Global electrification is the main driver of business for the family-owned company DEHN. The expansion of renewable energies, the growing share of electric vehicles, the necessary infrastructure, data centres and much more require products and solutions from the specialist for lightning protection, surge protection and safety equipment. The new production site in Piteşti, Romania, expands capacities for customers in Europe. The plant fits seamlessly into the company's existing global production network. "Piteşti gives us the flexibility we need to supply our customers in Europe even better," says Dr Philipp Dehn, CEO DEHN SE. "The plant underscores our internationalisation efforts and creates future-proof jobs in the greater Bucharest area."Open configuration optionsTo meet the anticipated global market demand, the company recently opened additional production sites in Mühlhausen (Germany) and Mooresville (North Carolina, USA). As the existing capacities in Germany will soon reach their limits, DEHN is now pushing ahead with the construction of an additional production facility for the European markets. After an intensive search for a location, during which several cities and regions throughout Europe were evaluated, the decision fell in favour of Piteşti, located north-west of the Romanian capital Bucharest. The combination of a well-trained workforce, very good local conditions and sufficient space for the construction project were the key arguments in favour of the new site in the CTPark Piteşti. DEHN plans to invest around 10 million euros in this Eastern European plant over the coming years. While the production sites in Neumarkt and Mühlhausen will primarily focus on high-volume products and highly automated processes in future, the focus in Romania will be on customised surge protection products in smaller quantities that require a high level of manual production.The ground-breaking ceremony marks the start of an approximately 10-month construction phase.

DEHN joins the Open Direct Current Alliance
DC technology plays a key role in the modern energy landscape. Whether photovoltaics, battery storage systems or charging stations, DEHN has been dealing with the protection of DC systems for a long time. DEHN's involvement in the Open Direct Current Alliance therefore marks a further milestone in the lightning and surge protection specialist's endeavour to shape the future of the electrical industry with innovative and sustainable solutions. DEHN has already successfully participated in the DC-INDUSTRIE research project, which investigated the advantages and potential of DC technologies in industrial applications.‘Our membership of the Open DC Alliance once again symbolises our commitment to promoting sustainable and innovative energy solutions,’ said Christian Höhler, CTO of DEHN SE. ‘We look forward to being at the forefront of DC technology, alongside other industry leaders, and actively shaping the future of energy supply.’The Open DC Alliance is a leading consortium dedicated to promoting and standardising DC technologies. As a member of the Alliance, DEHN can contribute to the development and implementation of future-oriented DC solutions that improve the efficiency and environmental impact of the energy supply. DC technologies offer significant environmental benefits. They reduce energy losses and increase energy efficiency which, in turn, reduces CO₂ emissions and allows a more sustainable use of resources.Renewable energies, like photovoltaic systems, and storage systems, such as fuel cells, can be integrated much more efficiently into a DC grid. That is why direct current is an essential component for the success of the energy transition. The two DC INDUSTRIE research projects reveal that energy consumption in existing systems can be reduced by up to ten per cent. Another benefit is the reduced need for copper in conductors. While conductors with four to five wires are required for alternating voltage, one to two wires less are needed for direct voltage. This represents a copper saving of more than 40 per cent.For many years, DEHN has been committed to protecting DC systems and offers customised protection solutions. The company has a DC test field where surges and DC networks can be simulated. The specific source characteristics of PV systems can also be reproduced there.The company was particularly active in the forerunner project DC-INDUSTRIE and was able to gain valuable insights and experience. These are channelled into pilot projects dealing with DC grids in industrial applications and buildings. DEHN supplies, for example, DC surge arresters for local public transport systems and special surge protection solutions for photovoltaic systems.Further information on DEHN’s DC range or sustainability efforts (sustainability | DEHN) can be found on our website DEHN - lightning protection, surge protection, safety equipment.
