Gas Discharge Tube Arresters (GDT) are a type of surge arresters that are used to protect electrical power systems from transient overvoltage events like lightning and switching surges. GDTs are a combination of resistors, gas-filled tubes, and a spark gap, and are designed to dissipate extremely high voltages. GDTs work by limiting the voltage at a predetermined level and diverting it to ground. This effectively reduces the transient voltages of any system they are attached to.

The 2027-35-BT1LF GDT arrester is specially designed for low-voltage applications such as voltage transformers, then low-voltage power lines, LED lighting, and solar inverters. It consists of a steel housing filled with polycarbonate, zinc oxide elements, and noble gases, and is designed to protect against overvoltages up to 4.6kV. It has a maximum continuous operating voltage of 1.3kV and an operating current range of 2mA to 20mA.

The 2027-35-BT1LF GDT arrester works in two ways. First, it uses resistive elements to absorb lightning surges and high-frequency voltages, reducing their output. These resistive elements then shunts the surges to ground, away from sensitive equipment. Second, it uses a spark gap design to dissipate the remaining high voltages. By limiting the voltage, it makes sure that any surge is safely dissipated away from sensitive components. This helps to protect both connected equipment and the electrical system itself.

In addition to its excellent surge protection capabilities, the 2027-35-BT1LF GDT boasts a long service life and is designed to withstand harsh environmental conditions. It has an operating temperature range of -55°C to +105°C and a total service life of up to 200,000 hours. Moreover, it features a high remanence and high energy absorption capability, making it suitable for both low-voltage and high-voltage applications.

Overall, the 2027-35-BT1LF GDT is an excellent option for protecting low-voltage electrical systems from transient overvoltages. Its combination of resistive elements and spark gap design ensures high energy absorption and long service life. Its superior environmental resistance makes it suitable for outdoor applications, while its low operating voltage range lets it be used for many low-voltage electrical systems, such as LED lighting, voltage transformers, and solar inverters.
