Gas Discharge Tube Arresters (GDT) are one of the most important elements for power system protection and lightning power protection. SL1021B250RG is a Gas Discharge Tube Arrester (GDT). It is mainly used for power line short circuit protection, lightning surge protection and overvoltage protection. It is also called a lightning arrester or surge arrester.

Application Field

SL1021B250RG is suitable for protecting the equipment from overvoltage that is normally caused by lightning and the over voltage produced by short-circuit fault. For each line induced by high voltage, SL1021B250RG can flow the over voltage current to the earth wire to protect the equipment. It can also protect the electrical system from damage when the voltage is high. SL1021B250RG is mainly used for lightning protection of power lines, cable communication, low-pressure power transformer and distribution line, as well as single-phase electrical circuit, and is widely used in various industries.

Working Principle

SL1021B250RG has a special internal structure. At normal voltage, SL1021B250RG works in a non-conductive state, and its two ends will not be electrically connected. In this state, electric energy will not flow through the arrester. When the voltage rises, SL1021B250RG enters the breakdown state, and its two ends are electrically connected. At this point, the electric energy will begin to flow through the arrester and be released in the form of heat. When the voltage returns to a safe level, the arrester will automatically return to the non-conductive state, and electric energy will no longer flow through the arrester. The arrester has its own reaction speed and release speed so that it can effectively protect the equipment.

SL1021B250RG has the advantages of high energy absorption capacity, fast response speed, and strong surge protection capacity. The GDT arrester adopts a unique composite structure design, which can reduce the gap sparkover voltage and reduce the capacitive coupling effect. Its fast response speed can reduce the overvoltage time, reduce the equipment damage rate, and increase the work efficiency. It can reduce the overvoltage influence on the equipment and avoid the secondary damage caused by the failure of the power system. It has the advantages of simple installation, reliable performance, and long service life, and makes the safety of the power system work to the greatest extent.
