Gas Discharge Tube Arresters (GDT)

Gas Discharge Tube (GDT) arresters are used for power engineering applications where they are used to protect devices and electronics in medium voltage systems. They are also known as Spark Gaps or Lightening Arrestors. They protect against electrical overloads caused by power outages due to natural disasters, which helps to preserve and protect circuit equipment in the network.

2031-42T-SM-RPLF gas discharge tube arrester is designed for indoor and outdoor medium-voltage power systems. This type of GDT provides superior protection against surges caused by lightning, transients from the switching of capacitors, and flicker from variable speed drive loads. The device consists of an outer polyethylene shell, which is filled with an arrester mixture. The inner part of the device is composed of a ceramic tube, filled with a metal oxide or sodium molybdate.

The working principle of a 2031-42T-SM-RPLF GDT arrester is very simple. The device is connected to the system’s phase line and neutral line. When a surge occurs, the arrester’s mixture is forced through the ceramic tube and forms a conducting path. This conducting path transfers the surge current away from the equipment being protected. As the surge passes through the ceramic tube, the electrically charged metal oxide particles in the mixture become charged, and create an electric field that prevents further surges from entering the system. Once the surge is over, the electric field dissipates, and the particles return to their neutral state.

The 2031-42T-SM-RPLF GDT arrester is designed with a high energy handling capability. It is able to absorb and dissipate more energy than a solid state arrester, making it more reliable and providing better protection for sensitive equipment. Additionally, its ceramic design ensures that the device maintains its performance even after multiple surge events. The device also offers a wide variety of installation configurations, making it suitable for almost any application.

In conclusion, 2031-42T-SM-RPLF GDT arresters are reliable and efficient surge protection devices. They are designed to protect sensitive equipment from power outages due to natural disasters, and their ceramic design provides excellent energy handling capacity. They can be installed in various configurations, making them a versatile choice for a wide range of applications.
