Gas discharge tube (GDT) arresters are devices used to protect power systems from transient voltages caused by lightning. The 2028-35-ALF is an example of a GDT arrester that uses a unique combination of materials and a sophisticated design to provide optimal protection against surges and lightning strikes.

Design and Construction

The 2028-35-ALF arrester is constructed from two electrodes; the main electrode and the auxiliary electrode. The main electrode is made from a metal compound and has a sharp pointed tip that helps to increase electrode energy, reducing arcing. The auxiliary electrode is constructed from a carbon impregnated silicone and is placed in an annular-shaped insulation mold, thus isolating it from the main electrode. Two pressure relief holes are also included in the design and act to dissipate energy quickly and safely in the event of a surge.

Working Principle

The working principle of the 2028-35-ALF arrester is based on the Zener diode effect. In the event of a surge, the high voltage is conducted into the GDT and connected to the main electrode. When the voltage exceeds a predetermined level (dependent on which materials are used in the construction of the arrester), electrons flow from the positive side of the main electrode to the neutral side, forming an electric arc. This arc is then dissipated through the two pressure relief holes.

Application Field

The 2028-35-ALF arrester is suited for use on electrical systems operating at below 35kV. Due to its unique construction and design, it can provide excellent protection against voltage surges, transients and lightning strikes. The arrester is also designed for use in environments with extreme weather conditions such as high humidity or salty air that could potentially corrode the electrodes or cause other types of damage.

Conclusion

The 2028-35-ALF gas discharge tube arrester is a reliable and effective means of protecting power systems from the effects of lightning and transient voltages. Its unique construction and design allow it to provide protection in even the most extreme weather conditions. The arrester works on the principle of Zener diode conduction and is suitable for use on electrical systems operating at below 35kV.
