Gas discharge tube (GDT) lightning arresters are widely used in various industries to protect electrical equipment from the damaging effects of lightning strikes. These devices are designed to provide a low-resistance path for the lightning current to flow, thereby diverting it away from sensitive equipment and preventing potential damage. In this article, we will explore some of the popular models of GDT lightning arresters and their common applications.One of the most commonly used GDT lightning arresters is the Littelfuse CG6 series. This series offers a wide range of models with different voltage ratings, making it suitable for various applications. The CG6 series is designed to provide reliable protection against lightning strikes and other transient voltage surges. It features a compact and robust design, making it suitable for use in both indoor and outdoor environments. The CG6 series also offers a high surge current handling capability, ensuring effective protection for sensitive equipment.
Another popular model of GDT lightning arrester is the Bourns 2049 series. This series is specifically designed for high-speed data line protection, making it ideal for applications in telecommunications and data centers. The 2049 series offers low capacitance and fast response time, ensuring minimal signal distortion and maximum data integrity. It also features a compact and surface-mountable design, making it easy to integrate into existing circuitry. The Bourns 2049 series is highly reliable and provides excellent protection against lightning-induced surges.
For applications requiring higher voltage ratings, the Phoenix Contact VAL-MS series is a popular choice. This series offers GDT lightning arresters with voltage ratings up to 1000V, making it suitable for use in industrial and commercial power distribution systems. The VAL-MS series features a modular design, allowing for easy installation and maintenance. It also offers a high discharge capacity, ensuring effective protection against lightning strikes and other transient voltage surges. The Phoenix Contact VAL-MS series is widely used in applications such as power plants, substations, and industrial control systems.
In addition to these popular models, there are several other GDT lightning arresters available in the market, each with its own unique features and specifications. Some of these models include the Siemens SITAS series, the Eaton CVM series, and the ABB OVR series. These models offer a wide range of voltage ratings, surge current handling capabilities, and other features to cater to different application requirements.
When selecting a GDT lightning arrester, it is important to consider factors such as the voltage rating of the equipment to be protected, the surge current handling capability of the arrester, and the specific application requirements. It is also essential to ensure that the arrester complies with relevant industry standards and regulations to guarantee its performance and reliability.
In conclusion, GDT lightning arresters are essential devices for protecting electrical equipment from the damaging effects of lightning strikes and transient voltage surges. The Littelfuse CG6 series, Bourns 2049 series, and Phoenix Contact VAL-MS series are some of the popular models available in the market. These models offer a wide range of voltage ratings, surge current handling capabilities, and other features to cater to different application requirements. When selecting a GDT lightning arrester, it is important to consider factors such as the voltage rating of the equipment, surge current handling capability, and compliance with industry standards.
