Gas Discharge Tube Arresters (GDT)

A Gas Discharge Tube Arresters (GDT), also known as a spark gap, is an electrical device used to limit the voltage between two points in the electrical system. It is used to protect circuits and components from voltage surges, such as lightning strikes and switching operations. Gas Discharge Tube Arresters (GDT) are basically employed as surge protectors, as they block and absorb high voltages to both living creatures and electronic equipment, and they are widely used in the industrial, transport and telecommunications applications.

Application field and working principle of 2027-09-B10LF

The 2027-09-B10LF is a type of Gas Discharge Tube Arresters (GDT) renowned for its outstanding performance. It has long shelf life, excellent safety performance and is widely used in the fields of high voltage protection and lightning protection. It is suitable for power transmission, power distribution, communications equipment, industrial control and other equipment.

The working principle of 2027-09-B10LF is fairly simple. When it is connected in series between two points of the power system, it has a high breakdown voltage, and the current flowing through it is basically zero until a transient event occurs, an abnormal surge or lightning strike. Once a transient event occurs, the GDT will switch rapidly from a high-resistance state to a low-resistance state, thereby dissipating the surge energy and limiting the current passing through it, thus protecting the system.

The 2027-09-B10LF GDT is usually composed of an anode tin oxide layer, an insulating porcelain body-casing or glass-casing, a gas-filled tube, and two electrodes. Upon a surge event, gas filled in the tube ionizes, and the electrons generated by the ionization process accelerate and collide between the electrodes, resulting in an arc discharge that increases the current conduction of the tube. This arc discharge dissipates the surge energy in a controlled manner, thus protecting the connected equipment from damage.

Conclusion

Gas Discharge Tube Arresters (GDT) are an essential component in the protection of power transmission and distribution systems. They are used to limit the voltage between two points in the power system to protect the equipment from voltage surges, lightning strikes and switching operations. The 2027-09-B10LF GDT has excellent safety performance and is perfectly suited for high voltage protection and lightning protection. Its working principle is straightforward, and it dissipates surge energy in a controlled way, thus ensuring a safer environment for both the living and electronic equipment.
