Gas Discharge Tube Arresters (GDT) is a type of protection devices used in electric power systems to protect against transient overvoltage caused by lightning or switching. SL1024A145R is a commonly used arrester with bidirectional lightning protection performance.

Application field

SL1024A145R is a type of silicon oxidevaristor arrester used in various lightning surge protector applications. It is particularly suitable for ensuring power transmission systems, distribution lines, and various types of electrical equipment against transient overvoltage due to lightning or other power surges. A typical application range of SL1024A145R is 0 to 150 kV (1.2/50us). Due to its impressive high-performance lightning protection capability, it is popular in both indoor and outdoor lightning protection applications.

Working Principle

SL1024A145R is a Gas Discharge Tube Arresters (GDT) composed of a gas-filled glass tube with a metal inside. When a large overvoltage surge enters the non-conductive gas filled glass tube, the electric force produced by the two electrodes of the metal electrode splits the gas molecules into positive and negative ions, resulting in an arc discharge between the electrodes. This process will absorb energy from the overvoltage surge and limit the peak value. Such fast and reliable action prevents the surge from damaging the protected equipment.

Physical Characteristics of SL1024A145R

SL1024A145R has eight standard sizes between 0.5 square inches and 2.2 square inches, ranging from 15kV to 150kV. It has a voltage limiting range of 0-150kV, a maximum limiting power 250 VA, and a maximum allowed continuous operating voltage of 125kV. The outer shell of the arrestor is made of stainless steel and reinforced glass, providing excellent physical protection of the internally insulated components.

Conclusion

SL1024A145R is a efficient and reliable Gas Discharge Tube Arresters (GDT) with bidirectional lightning protection capability. Its powerful voltage protection can be applied in multiple applications for both indoor and outdoor lightning protection. It is an ideal protection equipment for the power transmission system, distribution lines and other electric equipment.
