Introduction

Gas Discharge Tube (GDT) Arresters are components used to protect power systems from overvoltage surges. SL1021B090RS is a 10kV Gas Discharge Tube Arrester used for medium voltage applications. This arrester offers excellent performance, reliability, and low cost. It is suitable for a wide range of applications such as residential, commercial, and industrial.

Application Field

SL1021B090RS Gas Discharge Tube (GDT) Arrester is used to protect medium voltage power systems from overvoltage surges. It is used in applications such as residential, commercial, and industrial power systems. It is also suitable for intermittent or seasonal protection in telecom and power distribution systems.The SL1021B090RS Gas Discharge Tube Arrester offers a very high surge current rating due to its design and construction. It has a low Voltage Protection Service Level (VPSL) of 8.5kV, so it is able to provide effective protection from as low as 8.5kV surges up to 10kV.

Working principle

The working principle of the SL1021B090RS Gas Discharge Tube Arrester is based on the basic electrical principles of charge storage and discharge. When a surge is detected, the arrester acts as a switch, opening up the circuit and storing the excess electricity in a capacitor. The excess electricity is then allowed to discharge safely through the arrester, without damaging the power system.The SL1021B090RS has a unique hermetically sealed design which eliminates air exhaustion from the arrester. This design ensures reliable operation in harsh environments and offers superior performance in terms of surge current handling.

Conclusion

SL1021B090RS is a 10kV Gas Discharge Tube Arrester suitable for medium voltage applications. It offers excellent performance, reliability, and low cost. The unique hermetically sealed design ensures reliable operation in harsh environments. It is suitable for a wide range of applications such as residential, commercial, and industrial power systems.
