Surge arrester is one of the equipment that investors are interested in to install for their projects to ensure the safety of the project's facilities, as well as to ensure the safety of customers. people using the project as well as around the project.

- Surge protection devices are one of the most important devices that need to be installed in construction projects with the purpose of ensuring safety for people and material assets.

- Based on access to new technology, as well as consumer needs, pcccdongnam.vn has researched and proposed lightning protection solutions with outstanding efficiency and quality with a system of lightning protection devices. Dedicated spread, technical assurance. Ensuring the best service and protection for the lives of apartment buildings, houses, villas,... as well as public works.

Choosing suitable lightning protection devices for a project is very important. To choose the right lightning protection device for a project, it is necessary to rely on many factors such as power source, climatic conditions, and capacity. Integrated with alarm switch,...

Outstanding features of surge protection devices:

- Able to withstand high overpressure.

- There is a system to report the working status of the device.

- Low residual voltage.

- Able to cut high lightning pulses and cut many pulses.

- Low pass filter, lightning filter, power filter and noise filter. Applications of surge protection devices:

- Ensure safety for electrical, electronic, telecommunications equipment, etc. when struck by lightning on power supply lines.

- Lightning and surge protection for telephone/fax/modern/ADSL/ISDN lines.

- Made with modern equipment, techniques and technology, good for areas with high lightning density. To install effective lightning protection devices, you need to consider the following two issues:

Location of installation of surge protection devices: It is necessary to find out which type of lightning protection device is suitable for each type of circuit and protection location, and which locations should be installed with surge protection devices. Among construction equipment, communication equipment is one of the devices at risk of damage due to inductive pulses on the signal lines connected to these devices. The most reasonable method of reducing this risk and saving costs is to use lightning protection barriers placed at both ends of the wire. For high-rise buildings, the highest risk is present on communication lines and building entry/exit signals. In this case, lightning protection devices should be installed at the point of entry into the building or at the equipment end. How to select equipment for the designated location?

To choose a surge protection device suitable for the specified location, you need to pay attention to the following factors:

1. The device must withstand the maximum signal current.

2. The connection terminals, number of protection lines, installation method and other physical characteristics are evaluated and considered.

3. Surge protection devices must be designed to clamp excessive surges safely to the equipment and not affect the normal signal voltage. The clamping voltage of the selected lightning arrester must match the maximum working voltage of the circuit.

4. The lightning protection device bandwidth must be sufficient for the system to operate smoothly without causing signal degradation.

5. The overvoltage protection level of the surge protection device must correspond to the installation location. For high-rise buildings, the minimum protection level is 0.25kA. For circuits connected to input/output lines outside the building, the recommended protection level is 10-20kA. Hopefully with the above information, you have understood some notes in installing a system of lightning protection devices.
