Gas Discharge Tube Arresters (GDT) are electrical components that are used extensively in order to protect electrical circuits from lightning and other transient surge voltages. The 2026-47-C3LF is a type of GDT tha has matured over the years to become a standard product offering included in almost every line of surge arresters. This article will discuss the application field and working principle of the 2026-47-C3LF.

As stated earlier, GDTs are primarily used to protect against transient surge voltages. They are often used in residential and commercial applications such as in fire alarm systems, data networks, and telecommunications equipment. The 2026-47-C3LF is particularly well suited for frequent lightning surge surge protection in power distribution systems, optical fiber systems, and outside plant applications. It has an outstanding insulation performance, with an insulation breakdown voltage of 6500V x 5kA. The excellent impulse lightning protection level of 20kV combined with a very low let through voltage provides superior surge protection capabilities.

The working principle of the 2026-47-C3LF can be broken down into two parts: the insulation component and the current limiting component.

The insulation component is composed of multiple layers of insulation and is designed to prevent electric current from flowing through the arrester and bypassing the GDT. The insulation component also sustains relatively high voltage levels of difference between the high and low sides of the circuit, creating a greater electric potential difference that can be used to effectively extinguish the surge in question.

The current limiting component works by utilizing a nonconducting corona barrier that shuts off the current flow when the voltage on the conductor reaches a predetermined level. As a result, the current is limited to a specific amount and does not exceed the current limiting capacity of the arrester. In other words, the GDT can only permit a certain amount of current to pass through it.

The combination of the insulation component and the current limiting component make the 2026-47-C3LF an ideal choice for surge protection applications. It is compact and easy to install with a low insertion loss performance. The 2026-47-C3LF can also be used in applications that need a high level of surge protection and low long-term maintenance costs. With its impressive performance characteristics, the 2026-47-C3LF is sure to be an effective solution for many surge protection requirements.
