GDT, short for Gas Discharge Tube Arresters, is an important type of switching components used in the electronic circuit. It is mostly used to protect sensitive electronic devices from damage caused by transient high voltage. The SL1411A470C belongs to this type of protection component in principles and application field.

The SL1411A470C is designed specifically for voltage protection applications. It is a single-row unidirectional arrestor that maximizes surge protection performance and efficiency. It is specially designed for power line protection, including power transmission lines, medium voltage power substations and related applications. This arrester has a very stable discharge rating throughout its lifetime with a low service fee.

The working principle of the SL1411A470C is based on the gas discharge tube (GDT) technology. This arrester uses an arc discharge tube containing a special gas mixture composition to protect the device against transient voltage surges. It works by intercepting the fast surge current quickly and providing a secure ground path for the current to flow away. The arc discharge tube reduces the energy of the surge by dissipating the energy as heat, thus preventing physical damage to electrical circuits.

When a transient voltage surge reaches the SL1411A470C, the breakdown occurs and the current is discharged through the gas arc discharge tube. The tube regulates the current with the pressure of the gas that is contained in the arc discharge tube. As the pressure increases, the gas conducts the current and the arrester dissipates the extra energy as heat. Meanwhile, the arrester prevents the transient voltage surge from travelling further downstream. Eventually, the current flow stops and the voltage returns to its steady state.

The SL1411A470C has been tested and certified for various standards, such as IEC61439 Part I-IV, IEC 61643-21 and ANSI C37.90. It is also designed to withstand extreme environmental conditions, ranging from -25℃ to +90℃. In addition, its excellent remote indication features and security information enable convenient condition verification during fault diagnosis.

The SL1411A470C is designed to offer the highest level of protection against surges and fault currents. It is an ideal choice for protecting sensitive electronic devices in any power transmission and distribution network. Additionally, its advanced features, superior performance and reliability make it suitable for a variety of high voltage protection applications. With its excellent surge protection performance, the SL1411A470C is a reliable protective device for ensuring long-term safety.
