Gas Discharge Tube Arresters (GDT) are one type of surge protection devices used in electrical and electronic equipment to protect from transient high voltages. They are also known as spark gaps, gas tubes, and lightning arresters. GDTs generally have very low resistance to allow only a very small amount of current to pass when installed in a system. When exposed to a surge or lightning strike, the current flow increases sharply, causing the gas filling the tube to ionise and act as an electrical conductor. This conductor is then able to divert the high energy surge away from the protected system, thus providing the needed protection.

2027-42-ALF is a type of Gas Discharge Tube Arrester specifically designed to protect from transient high voltage and lightning strikes in the telecommunications industry. It is a positive temperature coefficient (PTC) type GDT arrester, which means that its resistance increases when its temperature increases. This curve ensures that the protection is in an active state during the surge or lightning strike, allowing the current to be funneled safely away from the main transmission line.

The working principle behind the 2027-42-ALF GDT arrester is relatively simple. When the arrester is exposed to a transient high voltage or lightning, the voltage increases beyond the breaking voltage of the arrester, and the gas within the tube is ionised. This facilitates the breakdown of the gas within the tube, allowing current to flow through it until the voltage drops below the breakdown voltage of the arrester. Once the voltage drops, the gas will recombine, stopping the current flow and enabling the arrester to return to a non-conductive state.

The 2027-42-ALF Gas Discharge Tube Arrester is also designed to be able to handle high currents with ease. It is rated up to 200 A, which means it is suitable for use on many different types of lines, including aerial, underground, and power supply cables. It also features an adjustable protection level, allowing it to provide protection for different types of lines, ranging from low-voltage to high-voltage lines.

The 2027-42-ALF Gas Discharge Tube Arrester is a reliable and cost-effective surge protection solution that is suitable for a wide variety of applications in the telecommunications industry. Its simple and effective design ensures that it can protect any system from transient high voltages and lightning strikes, ensuring the safety of people and assets. Its adjustable protection level and high current rating make it an ideal choice for protecting both low and high-voltage lines, making it a great choice for any telecommunications company looking to keep their equipment safe from the dangers of lightning strikes.
