Gas Discharge Tube Arresters (GDT) are devices used in electrical circuits for the purpose of protection against transient surges or electrical over-voltages. Such arresters are made up of a combination of components such as diodes, capacitors, and gas-filled tubes in order to create the desired protection level. In particular, GTCA28-141M-R10 is a type of GDT that can reliably protect cables and other connected equipment from power surges that exceed the normal operating voltage.GTCA28-141M-R10 is a type of gas-filled tube arrester and typically consists of a gas filling core, a core lead, a support socket, and a metal case. The gas-filled core is composed of a combination of nonlinear resistors and a zone gap. This combination is made to regulate and suppress the over-voltages that occasionally occur in an electrical system. The core lead is responsible for connecting the core to the support socket and provides mechanical support. The support socket acts as an adapter between the core lead and the metal case, which also acts as an enclosure for the device. Inside the metal case, a spark gap is used to regulate any high transient voltages, thus providing effective protection against overvoltages.The basic working principle of GTCA28-141M-R10 gas-filled tube arresters is based on the concept of Zener voltage breakdown. When an over-voltage transient occurs, it causes the breakdown of the gas molecules in the tube. This causes an avalanche breakdown that immediately current-limit the surge current. As such, the peak voltage of the surge is regulated or limited by the Zener voltage. Moreover, the device is able to continuously discharge high-frequency lightning surge current and reset itself after the surge has passed.GTCA28-141M-R10 is commonly used in a variety of applications such as in high-power electric power systems, telecommunication networks, industrial systems, as well as in cables and other places where protection against transient surges is desired. It has fast response time, operates in a wide temperature range of -40C to +160C, and can withstand voltage up to 50kV. Additionally, it has a surge current capacity of 18kA, making it suitable even for high current applications.In conclusion, GTCA28-141M-R10 is a gas-filled tube arrester that is used for protection against electrical over-voltages. It consists of a gas-filled core, a core lead, a support socket, and a metal case. The device uses a Zener voltage breakdown to control the surge current and provide effective protection. It has a fast response time, operates in a wide temperature range, and can withstand high voltage and current. With the numerous features offered, it is suitable for use in a variety of applications from high-power electric power systems to telecommunication networks.
