Pipelines are the lifeline of our industrialised society. Their reliable functioning is essential for many supply and production systems. Increased bundling of transportation and energy routes increases inductive and ohmic interference on pipelines. As a result, voltage can occur on and damage pipelines. This may present a hazard to people, material assets and the environment, often resulting in high repair costs. Interference voltages can be caused, for example, by nearby high-voltage transmission lines and railway lines, but also by earth faults and lightning currents. The screwable earth rod from DEHN is the solution for safe earthing. The very low earth electrode resistances achieved with it reduce the corresponding voltages on the pipelines to a minimum. Interference voltages are safely discharged, thus protecting pipelines and people.

More than 99 percent of German companies are small to medium size enterprises (SMEs). Not only do they account for around half of the country's total economic output. They also employ around 60 percent of the total workforce in Germany. Some of these companies stand out for their exceptional entrepreneurial drive and courageous plans for the future. Every year, the Bavarian State Ministry of Economic Affairs, Regional Development and Energy selects fifty exemplary Bavarian companies under the motto "Bavaria's Best 50" - and DEHN is once again one of this year's award winners.

A failure of sensitive, networked technology, whether in industry, infrastructure or even in residential and office buildings, is unacceptable and often has serious consequences. DEHN, one of the world's leading suppliers of surge protection, lightning protection, earthing and safety equipment, offers protection solutions for industry, photovoltaic systems, e-mobility charging infrastructure, energy storage systems, LED lighting, railway infrastructure or even residential and office buildings, for example – in tailor-made fashion to meet all different requirements. "Mobilising electrification and digitalisation for a sustainable society", is the slogan for this year's ELFACK, one of the most important trade fairs in northern Europe for energy and electrification, which is taking place from 9 to 12 May 2023 in Gothenburg. Accordingly, on the occasion of the first public appearance of DEHN Sverige at stand G00:40, DEHN will show how the challenges described can be solved easily and safely.

Over the past few years few topics have been as intensively discussed as our energy supply. What components should our energy mix have in the future to support the further development and expansion of the various megatrends of our time? Particularly in the recent past, the topic of hydrogen has become increasingly prominent, but only a few players are currently venturing into the subject. A first coordinated initiative is the " Hydrogen Center Bavaria (H2.B) ", which links partners from industry, science and politics. DEHN has been part of the alliance since the beginning of 2023. For regardless of whether it is a matter of producing or transporting "green hydrogen", comprehensive protection against lightning strikes and surges is essential.

Smart technological solutions for residential and functional buildings, and networked systems in infrastructure and industry, are currently the state of the art. Maximum availability is a prerequisite here. Malfunctions with unscheduled downtimes can quickly cause significant additional work associated with extremely high costs. The reliability and protection of sensitive systems is therefore of the highest priority. Comprehensive lightning and surge protection is an essential component in rendering installations and systems safer and more reliable, and thus more efficient. At this year’s Light + Building, from 2 to 6 October, DEHN is presenting pioneering protection solutions for a wide variety of fields – be it for residential buildings, industrial buildings, data centres or e-mobility.

Advancing digitalisation demands an ever faster supply of data.  High transmission volumes and ever improving bandwidths are a prerequisite. Structured cabling is an important component of today's network topology for information and data technology. In this context, safety is a multifaceted topic, in which lightning current and surge arresters play an important role. The new DEHNpatch DPA CL8 EA 4PPOE arrester is designed for use in a switchgear cabinet or data distributor and can handle data rates of up to 10 GBit/s.  With Power over Ethernet (up to 4PPoE with a power transmission of up to 100 W), class EA transmission standard (max. 500 MHz), status indication and the possibility of remote signalling, the DEHNpatch is equipped for modern applications. Available bandwidths can be maxxed out while undisrupted data transmission can be ensured.

DEHN and Max Bögl collaborate on a wind tower project

How to prevent damage to a wind turbine as best as possible if lightning strikes the exposed tower? This was the question posed to simulation experts from DEHN along with the Max Bögl Group in a project. Now both companies are benefitting from the results.

Equipotential bonding is essential; particularly in potentially explosive areas. It eliminates differences in potential, thus preventing dangerous touch voltages and sparking. In order to achieve this, all external, conductive system parts and installations that could cause dangerous potential differences must be connected to the main earthing busbar.

In just 4 standard DIN modules, the compact combined arrester, type 1+2+3, protects against transient overvoltages in low-voltage switchgear and controlgear assemblies. Small width and a compact single module that saves you time during installation and maintenance.
