Gas Discharge Tube Arresters (GDT) are voltage limiting devices designed to protect electrical equipment from potentially damaging effects of lightning surges or induced transients. GDTs are constructed using two electrodes, a central electrode and a ground electrode, with a controlled amount of insulating material in between. When connected to a power source, a GDT will act like a voltage clamp, absorbing excess voltage that is above a certain threshold, typically 5 to 10 kilovolts.

2026-23-C2LF is a GDT model designed and manufactured by Siemens. This model is designed for use in high voltage power distribution systems, offering protection from transient events. The 2026-23-C2LF features a 20mm diameter tube and uses nitrogen as its discharge gas. Its voltage rating is 11kV, with an energy absorption capacity of 63.6 Joules.

The 2026-23-C2LF GDT is designed to function by redirecting surplus or disruptive voltage away from sensitive components or wiring. During normal operation, the 2026-23-C2LF does not interfere with or reduce the electrical flow. Once a threshold voltage is exceeded, the device will automatically trip to divert the voltage away, before resetting itself when the voltage returns to a safe level. This allows for effective protection against damaging transient surges.

The 2026-23-C2LF GDT has a number of application fields, including but not limited to AC/DC welding, power distribution systems, renewable energy systems, solar power systems, and electric vehicles. This type of GDT is particularly suitable for use in applications that require a high degree of reliability and protection from external influences.

The working principle of the 2026-23-C2LF GDT is simple yet effective. When the voltage across the tube rises above its rated threshold (usually 5 - 10 kV), a breakdown of the dielectric material occurs. Due to the nature of the breakdown, an arc is created in the tube and this arc forms a low resistance path between the two electrodes. This causes the voltage to be diverted away from the sensitive equipment and towards the ground, protecting it from potential damage.

Once the voltage returns to a safe level, the GDT automatically reset itself and the arc in the tube dissipates. This means that the GDT can be used in high voltage systems without the need for constant resetting and maintenance, ensuring a reliable operation.

The 2026-23-C2LF GDT is a reliable and effective method of voltage limiting and surge protection. It is easy to install, highly reliable, and provides protection from damaging transient events in a wide range of applications. The 2026-23-C2LF is a cost-effective method of protection and an excellent choice for high voltage power distribution systems.
