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.
