Gas Discharge Tube Arresters (GDT)
The gas discharge tube arresters (GDT) is a class of electrical surge arresters that protect electrical systems from various lightning and power surge-induced overvoltages. GDTs are composed of two metal plates or cylinders, these cylinders are separated by an insulator. An arc is created when the voltage reaches a certain level, and this arc extinguishes the electrical spike. GDTs are typically used in outdoor power systems to protect them from hazardous over voltage transients that can be induced by lighting, switching operations, and other electrical events. GDT arresters are known for their cost-effectiveness, reliability, and durability.

The 2028-25-ALF GDT arrester is a popular model of GDT from one of the most trusted arrester manufacturers. It is designed for outdoor use in medium-voltage applications and is rated for a maximum operating voltage of 46kV. The device is also tested to withstand an impulse of 105kV, meaning it can protect against the most intense surges that might occur. The device is also resistant to thermal stress and offers a long service life.

The 2028-25-ALF arrester has a 10-20kA discharge current rating and operates by having an incoming surge-induced current flow from the line side to the ground side. This current causes the arrestor to discharge, which then extinguishes the voltage spike. The arrester is also equipped with a spark gap which creates a safe path for the discharge current to flow. This helps to reduce the amount of heat generated by the device during operation. The device can also help reduce corona losses by controlling the electric field.

In general, the 2028-25-ALF GDT arrester is designed for outdoor use and is suitable for a wide range of applications, from distribution networks to industrial machinery. It can provide long-term protection against lightning and other overvoltage surges, and its durability makes it an excellent choice for areas with harsh environmental conditions.
