Coordinated Type 1 Lightning Current Arrester
- Coordinated spark-gap-based lightning current arrester
- Extremely high lightning current discharge capacity up to 200 kA (10/350 µs)
- Low voltage protection level UP ≤ 2.5 kV
- Extremely robust design for installation on busbars or mounting plates
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.
