Protection solutions
DEHN supplies comprehensive protection solutions in the fields of surge protection, lightning protection/earthing and safety equipment for many different industries.
Buildings
Surges pose a risk to buildings. Surges result from, e.g.,
- Indirect lightning strikes
- Direct lightning strikes
- Switching overvoltage in the power grid
- Self-generated switching overvoltage
Protect your power and data lines and don’t give surges even the chance to cause damage.
 | Indirect lightning strikes - when lightning strikes overhead lines, trees or the ground, surges can enter buildings via data and power lines. There, they can damage or destroy electrical equipment. |
 | Direct lightning strikes - the enormous amount of energy in a direct lightning strike can damage the roof and set it on fire. Here, external lightning protection comes into its own. |
| Switching overvoltage in the power grid - switching operations in the power grid can generate surges. These are transmitted to buildings via power lines. |  |
| Self-generated switching overvoltage - Surges can also be generated by devices in your own network, e.g., when switching the air-conditioning or a flow heater on or off. |  |

Cell sites
Reliable protection against lightning and surge damage is an important aspect when redesigning and extending the existing network infrastructure.
New transmission technologies require constant hardware adaptions. The higher the investment costs, the more important it becomes to protect the installation from damage that may lead to downtime.
Prevent lightning damage to the host building, mobile radio infrastructure and electrical systems.
Oil and Gas Industry
Chemical and petrochemical systems bear a high risk due to their large surface area, isolated location and design. Their high-tech measuring and control systems are both expensive and vulnerable.
Protect the electrical and electronic installations in the oil and gas sector.
Transportation
Protect highly sensitive electronic systems in the field of railway transportation. Buildings, systems and associated electronic equipment are vulnerable to lightning strikes and electromagnetic interference.
