DSO 1 255: Coordinated single-pole lightning current arrester with an extremely high lightning current discharge capacity
Details
The spark gap of the coordinated DEHNsolid lightning current arrester has an extremely high lightning current discharge capacity of 200 kA (10/350 µs), making DEHNsolid the most powerful lightning current arrester currently available on the market. Consequently, a technical solution is now available for applications where such powerful surge protective devices are required. The device ensures lightning protection if the lightning current is not distributed and thus the full lightning current may flow through the surge protective device. If a lightning protection level higher than LPL I according to EN 62305 is to be expected, DEHNsolid offers adequate protection.
DEHNsolid features a robust design due to its extreme installation conditions and can be installed in two different ways. On the one hand, the arrester can be directly mounted on the busbar. This ensures a mechanically stable installation, which is required in case of such extreme lightning currents due to the high forces, and short low-impedance connections. On the other hand, the arrester can be screwed onto a mounting plate / fixing unit using the fixing lugs if it is not possible to install it on a busbar. Extremely short and robust connecting cables are required for this device to ensure mechanical strength of the entire arrangement and a minimum voltage drop on the connecting cables to achieve an optimal voltage protection level for the installation.
