Gas Discharge Tube (GDT) arresters provide electrical protection against damage caused by lightning or other transient overvoltages. GDT is a kind of semiconductor, the main task is to protect against high-voltage transients, which can cause malfunction or damage to electrical equipment. 2036-42-B2 gas discharge tube has its own application field and working principle.

2036-42-B2 GDT mainly applies to AC systems at a power frequency of 50/60 Hz or DC systems as a protective device. This type of product also fits high-voltage circuit breakers, cables, switchboards, tractors, ships, electronic circuit boards, telecommunications, relay protection, building lightning protection and various other fields. The electrical control equipment mentioned above are usually subjected to voltage surges or lightning surges, resulting in failure or loss of performance, and need to be equipped with 2036-42-B2 arrester.

The 2036-42-B2 arrester performs its role by getting rid of transient currents. If there is a breakdown or surge in the power line due to an external electrostatic discharge, strong lightning or other disturbances, the arrester will automatically operate and carry the transient voltage personnel to the ground safely. This type of gas discharge tube is a bipolar type, which means that it can pass current in two directions. The internal structure of the arrester includes an alumina outer glow tube, which contains a ZnO arrest element and electrodes.

The working principle of the 2036-42-B2 arrester is to allow the normal working voltage to pass through, and act to break down the unduly high voltage. Due to its self-recovery characteristics, the metal oxide surge arrester can quickly extinguish the arc without damage of the internals and produce a low residual voltage.

2036-42-B2 GDT is able to withstand a much higher voltage rating than other conventional arresters. This type of arrestor is typically used to protect electric systems from Lightning, Impulse or Electrostatic Discharge events with a voltage rating of up to 42kV. It also has high-powered surge capacitance, supporting double-responded protection. It also features excellent surge current withstand capabilities with an 8/20μs 100kA maximum discharge current.

In order to ensure the safe operation of equipment and longer service life, it is recommended that 2036-42-B2 arrester be installed in the circuit with respect to the relevant standards. Its characteristics need to be tested professionally and certified, to ensure that the arrester is able to protect the power line from surge and spike.
