Gas Discharge Tube Arresters (GDT) are an indispensable piece of technology in the modern world. They are used to protect electrical systems from intense electrical current or voltage fluctuations, by automatically disconnecting the system from the power source when an overvoltage or undervoltage occurs. GDTs may also be referred to as surge arresters, spark gaps, gas cans, lightning terminators, or transients.

The 2028-42-C2LF is a Gas Discharge Tube Arrester (GDT) that is designed for overhead power line applications, and used to protect high voltage transmission lines, transformers, switchgear, and other electrical equipment against switching surges and lightning strikes. It is composed of a Metal-Oxide Varistor (MOV) and an ozone protected, heavy duty air core GDT, which are connected in parallel with a self-reset feature in the arrester.

The MOV element of the 2028-42-C2LF is designed to absorb and disperse high frequency noise, while allowing passage of lower frequency power without affecting its operation. When subjected to a sudden surge, the MOV element immediately increases its resistance, absorbing most of the surge voltage. The GDT will then trigger and limit the voltage that is passed to the secondary components.

The heavy duty air-core GDT utilizes air gaps that operate within a high voltage rating. It is housed in a flameproof enclosure and is designed to provide the greatest protection against sparks and arcing. Whenever an abnormal voltage occurs, the GDT will be activated and begin to operate simultaneously with the MOV. Upon contact of the current and voltage, an arc will be generated, which is attracted towards the next gap due to electrostatic forces. The arc is eventually extinguished by the compression of air as the air expands between each gap in the GDT.

The 2028-42-C2LF automatically resets itself after the event is over. This ensures that the power system is back in balance and the voltage is back to its nominal voltage. GDT\'s can also be used as direct current detectors, as the arcing will be permanent for certain DC conditions. The 2028-42-C2LF is designed to withstand a wide range of temperatures and environmental conditions, and is UL489 approved.

The 2028-42-C2LF has a wide range of applications, including high voltage power lines, power stations, underground transformations, service drops, and communications buildings. It can be used in residential, commercial, and industrial applications, and is ideal for both alternating current (AC) and direct current (DC).

The 2028-42-C2LF Gas Discharge Tube Arrester (GDT) is one of the safest and most reliable devices available for protecting electrical systems against intense current or voltage fluctuations. It offers superior protection against surges, lightning, and arcing, as well as reliable self-resetting features. This GDT provides the assurance and peace of mind needed to ensure that your electrical systems will remain safe and operational.
