DEHN protects.

The powerful natural phenomenon of lightning has

fascinated mankind since the beginning of time. In

Greek mythology Zeus, the Father of Gods, is seen as

the ruler of Heavens and his power is often depicted

as a lightning bolt. The Romans attributed this same

power to Jupiter, the continental Germanic tribes to

Donar, and the North Germans to Thor. For a long

time, the enormous force of a thunderstorm was

associated with a supernatural power and humans

felt at the mercy of this power. Since the Age of

Enlightenment and the advancement of science, this

heavenly spectacle has been regarded in a more sober

light. In 1752, the kite experiment by the inventor and

statesman Benjamin Franklin demonstrated that the

phenomenon of lightning is in fact the equalisation

of an electric charge.

Lightning: Fascinating, but dangerous

2

Although nowadays we understand what is behind

this natural phenomenon, it is fascinating to watch,

and extremely dangerous. Every year, lightning kills

people and animals and destroys material assets. Most

of these deadly consequences can be prevented by

taking appropriate protection measures.

Thunderstorms in times of climate change

Increasing weather extremes: Meteorological data

say that thunderstorms are on the rise even in the

moderate European climate. In Germany alone, more

than two million lightning events are recorded every

year and the tendency is rising. Violent thunderstorms

threaten lives and cause severe damage: Hail destroys

roofs or cars, lightning strikes cause fire or surge dam-

age to electrical or electronic devices and systems and

may completely destroy them. Lightning strikes have

particularly fatal consequences in the industrial, power

generation or infrastructure sector: System failures and

production downtimes result in substantial financial

loss, and failure of fire alarm systems or emergency

centres put lives at risk.

Lightning and surge protection from DEHN

In 1910, the electrician and precision engineer Hans

Dehn set up an electrical installation company in

Nuremberg. As Hans Dehn had successfully completed

his training as a state-registered installer of lightning

rods, the installation of lightning protection systems

became an integral part of the young company

right from the start. Fascinated by external lightning

protection, Hans Dehn came up with his first lightning

protection invention in 1918 and registered his first

patent on this subject. Further patents followed in the

course of the company’s history.

“First and foremost, our innovations must benefit our customers.”Dr.-Ing. Peter Zahlmann, Managing Director

We heavily invest in research and development to create

innovative products and to continuously improve our prod-

ucts, their quality and ease of installation. 285 international

patents and inventions for numerous DEHN products and

solutions are the result of our development work. To this end,

we always have an eye on our customers’ wishes and needs.

The feedback from standardisation committees, cooperation

with research institutions and international technical confer-

ences are also considered for new and further developments

of our products.

As part of our corporate strategy, our products have to satisfy

high, uniform quality standards. They are designed so as to

meet the basic requirements of the relevant standards and

the technical prerequisites of the specific field of application.

Our products can be used in the widest variety of applica-

tions, though our focus remains on special industry and

customer solutions.

universities and research institutions.

Developing innovations

9 10

Innovative strength and flexibility are the key pillars of

our company and the driving force that encourages us

– as a technological leader – to new ideas, further de-

velopments and solutions tailored to customer needs.

Many examples from DEHN’s more than 100-year histo-

ry prove that success in the fields of surge protection,

lightning protection and safety equipment, not only

requires visionary thinking, know-how and experience,

but also persistence.

Unique test laboratory

A decisive factor is our renowned impulse current labora-

tory. It is essential for the successful development of new

products, systems and protection concepts: It allows us to

perform tests with lightning currents up to 400 kA (10/350

µs) under realistic conditions. For many years now, we

have been studying the characteristics of natural lightning

strikes in a lightning measuring station in Austria where

natural lightning strikes are analysed and the phenome-

non of lightning is investigated. From the results of this

fundamental research, conclusions are drawn for product

development, standardisation and our test laboratories.

Most stringent quality standards worldwide

Our aim is to provide top quality. This means that the best

materials are used for our products, most of the work steps

are carried out in-house and all products are inspected

before they leave our company. Our products and systems

comply with applicable standards. Products for the interna-

tional market can be adapted to meet the specific require-

ments of national standards. Our quality management

system is certified to the DIN EN ISO 9001 standard. All

these factors allow us to offer our customers safe, reliable

and durable products and protection solutions.

In dialogue with science

We finance an endowed professorship at the Ilmenau Uni-

versity of Technology to promote fundamental research on

modern methods, technologies and materials in the fields of

lightning and surge protection.

Numerous functional tests are performed to test the high quality of materials used in our products and components.

Clearly defined production processes form the basis for the production of high-quality products, for exam-ple the globally leading arresters from our Red/Line® product family.

In our unique impulse current laboratory we carry out product and system tests in line with international standards – also on behalf of our customers.
