Gas discharge tube arresters (GDT) are an important part of electrical surge protection equipment. The GTCN36-900M-R10 arrester is a type of GDT designed for applications with heavy lightning surges. It has rated lightning impulse voltage (LI) up to 900kV and rated discharge current (ID) up to 10kA.

GTCN36-900M-R10 has a high level of insulation and reliable discharge performance. It can effectively reduce or eliminate the noise generated by large amplitude induced lightning surges. This arrester is also designed to limit the impact of strong electric field under normal working conditions and will not remain in a highly conductive state after the surge.

The working principle of a GTCN36-900M-R10 arrester is based on the spark gap effect. This effect occurs when the voltage between two electrodes is increased beyond the breakdown voltage, causing a spark to form between them. This spark creates an ionization channel that conducts the surge current and protects the system from any further damage. The breakdown voltage of the GTCN36-900M-R10 is achieved through the combination of electrode shape, size, and insulation material. The main components of this arrester are the body, the electrodes, the insulation material, and the spark gap.

The body of a GTCN36-900M-R10 is typically made of anodized aluminum, copper, or stainless steel. The body contains the electrodes and insulation material. The electrodes are made up of two metal plates that are either oval or convex in shape. The insulation material between the two electrodes is designed to have a high dielectric strength and be resistant to aging, moisture, and ozone. The spark gap is typically filled with an insulating gas, such as nitrogen, argon, or air.

When the voltage across the GTCN36-900M-R10 arrester exceeds its breakdown voltage, a spark is formed between the two electrodes. This spark ionizes the gas inside the spark gap and creates a conducting path for the surge current. The spark is self-extinguishing, so that once the surge is over, the conduction is immediately interrupted and the spark gap returns to its highly insulating state.

The GTCN36-900M-R10 arrester is typically used in applications where lightning and over-voltage surges pose a significant risk to the system. Its combination of a high breakdown voltage, low failure rate, and high insulation performance makes it an ideal choice for protecting electrical systems from the dangers of lightning-induced surges. It is also commonly used in outdoor installations, such as in oil and gas extraction sites, power plants, substations, telecommunications, and military sites.
