Lightning Protection Solutions for Residents and Buildings
We offer a best solutions for Residents, Office and Commercial Buildings. Surges are a great danger. Direct, nearby and remote lightning strikes as well as switching operations in electric power stations can seriously damage buildings and systems. Many buildings and systems are exposed to lightning strikes and discharges, switching overvoltages, surges caused by short-circuits and switching off inductive loads. Apart from power supply systems, reliably functioning information technology systems are indispensable for smooth operation in office and administration building
Protect your residential buildings
In modern households, electrical devices and systems make life easier:
• TVs, stereo and video equipment, satellite systems
• Electric cookers, dish washers and washing machines, driers, refrigerators / freezers, coffee machines, etc.
• Laptops / PCs / tablet PCs, printers, smartphones, etc.
• Heating, air-conditioning and ventilation systems.
First step: System protection:-
The first step is to consider all lines leaving or entering the building: Power supply / telephone / lighting lines, TV / SAT connections, connections for PV systems, etc. In residential buildings, meters and sub-circuit distribution boards are often placed in one enclosure. For this purpose, DEHNshield comes in different versions to protect both the installation and the terminal devices on the power supply side, even in case of direct lightning strikes. DEHNbox can be provided for the telephone connection e.g. via DSL / ISDN. This arrester is sufficient to ensure safe operation of the DSL router. DEHNrail and BLITZDUCTOR®XT protect the controller of the heating system, which is often located in the basement. If there are further distribution boards, DEHNguard® surge arresters are to be installed.
Second step: Protection of terminal devices:-
The next step is to protect all terminal devices, which are fed by several power supply systems, by installing surge protective devices right at their inputs. These terminal devices include TVs, video and stereo equipment as well as alarm and video surveillance systems. The antenna amplifiers can be protected by means of DEHNgate.
Protection of power supply systems
Combined arresters such as DEHNvenCI and DEHNguard® surge arresters can be used to protect power supply systems. DEHNrail , SFL Protector or DEHNsafe protect terminal devices from surges and reduce induced voltages and switching overvoltages to safe values
Protection of information and telecommunication systems
To ensure safe operation, both data and voice transmission require adequate protection elements. Networks are typically designed in the form of universal cabling systems. Even if fibre optic cables between building and floor distributors are standard today, copper cables are typically installed between the floor distributor and the terminal device. Therefore, the HUBs, bridges or switches must be protected by NET Protector LSA 4TP.
DEHNpatch cables are used to protect terminal devices. The DEHN equipotential bonding enclosure, which can be fitted with LSA disconnection blocks and lightning current carrying DEHNrapid® LSA plug-in SPD blocks, can be provided for information technology lines extending beyond the building.
To protect the telecommunication system, NET Protector can be installed in the floor distributor to protect the outgoing lines to the system telephones. A data protection module, for example, can be used for the system telephones.
Protection of building automation systems
Failure of building automation systems can have fatal consequences. If the air-conditioning system fails as a result of surges, a data centre may have to be disconnected or a server may have to be shut down. Bus systems such as KNX / EIB or LON can be protected by BUStector, DEHNconnect or BLITZDUCTOR® XT.
