Gas Discharge Tube Arresters (GDT) are electrical components designed to provide surge protection to sensitive equipment from electrical lightning, electrical noise, and acts as a safeguard against overvoltage caused by high-pressure power surges. The components of GDT are comprised of a gas-filled tube, one or more electrodes, and a surge protective device. The gas-filled tube is typically made of aluminum oxide, and when a surge or anomaly occurs in the electrical system, it releases the stored energy to the other components of the surge protection circuit. The electrodes conduct the surge energy to the ground or another circuit and the surge protective device stops the flow of electricity when the surge is detected. GDTs are widely used for protection of power equipment in residential, industrial, and commercial environments.
2028-42-ALF are Gas Discharge Tube Arresters (GDT) specifically designed for use in electrical systems with higher levels of voltage. They are designed to detect high-energy surges, divert them away from equipment, and protect it from further harm. The 2028-42-ALF features a gas-filled tube made of a complex alloy of aluminum oxide, an electrode, a surge protective device, and special repellent foil that protects the components from dust and dirt, allowing for a high degree of reliability in operation.
The working principle of 2028-42-ALF is quite simple. When a surge or anomaly occurs in the electrical system, the gas-filled tube releases the stored energy to the other components of the surge protection circuit, the electrodes conduct it away, and the surge protective device interrupts the flow of electricity to maintain proper operation. By doing so, the 2028-42-ALF can successfully protect sensitive equipment from high-energy surges, lightning, and noise, helping to prevent costly damage.
The 2028-42-ALF is used in a variety of applications, including power lines, telephone lines, security systems, industrial equipment, and aerospace systems. In each case, it is essential that the components of the GDT are well maintained and regularly checked to ensure their proper functioning. With a relatively low cost and high durability, the 2028-42-ALF is a highly popular choice for surge protection needs.
In conclusion, 2028-42-ALF Gas Discharge Tube Arresters (GDT) are designed for use in high voltage electrical systems and are an excellent choice for providing surge protection for sensitive equipment. The gas-filled tube releases stored energy to the other components of the surge protection circuit when a surge or anomaly occurs, the electrodes conduct the surge energy to the ground or another circuit, and the surge protective device interrupts the flow of electricity to maintain proper operation. The 2028-42-ALF is used in a variety of applications, and its relatively low cost and high durability make it an attractive choice for surge protection needs.
