2057-15-BLF

Gas Discharge Tube Arresters (GDT) are used to protect electrical equipment and distribution systems from damaging over-voltages. These components work as an additional layer of protection between electrical circuits and lightning or power system faults.

The 2057-15-BLF arrester is one of the most versatile and widely used GDT arresters. It can be used in a variety of applications, including high voltage switching, surge protection, and lightning protection.

The 2057-15-BLF arrester is designed for switchgear applications with rated voltages up to 36 kV. It has a variety of features such as: a voltage rating up to 50 kV; a 160 ka short-time current rating; a short-circuit current breaking capacity of up to 15 ka; and a front and rear mounting arrangement.

The working principle of the 2057-15-BLF arrester is straightforward. When there is an over-voltage condition in the system, the arrester acts quickly to limit the amount of energy which is allowed to pass through the system. This prevents further damage to the components which are connected to the system.

The arrester has two major components: the gas-filled tube, and the spark gap. When over-voltage conditions occur, the gas-filled tube experiences a rapid increase in pressure. This pressure causes the spark gap between the two ends of the tube to close. This results in the arrester limiting the over-voltage and preventing further damage to the system.

The 2057-15-BLF arrester is one of the most widely used GDT arresters available. It is designed for a variety of applications and has a wide range of features. It is a reliable and efficient way to limit over-voltages and protect electrical equipment and distribution systems.
