Gas Discharge Tube Arresters (GDT)

2027-35-ALF is a type of Gas Discharge Tube Arresters (GDT). These are electrical components designed to protect electrical systems and components from surges caused by lightning strikes, power outages, and other transient events. GDTs have been utilized in a variety of industries and applications since the early 20th century.

2027-35-ALF GDTs are designed for surge protection and protect electrical circuits from the effects of transient events. They are manufactured with an outer insulating jacket, a gas-filled internal chamber, and an electrical contact assembly to activate the arrester.The most common types of GDTs are gas-filled surge arresters, varistor arresters, and spark gap arresters. Each of these types have different characteristics and offer different levels of protection.

The 2027-35-ALF GDT is a gas-filled surge arrester that utilizes an internal gas chamber that is filled with noble or inert gas at low pressure. The gas chamber contains two electrodes, and when a transient voltage spike is detected, the arrester will create a very short-lived bridge of ionized gas between the two electrodes, creating a pathway for the electrical surge to pass through. This discharge dissipates the surge energy and protects the electrical system it is connected to.

The 2027-35-ALF GDT is also equipped with internal movable contact points and a stainless steel case. This movable contact point, called the trip contact, allows the arrester to quickly and automatically identify changes in transient voltage spikes and reset itself afterwards. The stainless steel case is designed to offer an extra layer of protection against external environment and over-voltage conditions.

The 2027-35-ALF surge arrester is a low-voltage type that is designed to handle voltage spikes up to 100V. It is used in a wide range of electrical applications, including power grids, alternating current (AC) systems, and direct-current (DC) systems. In addition, GDTs are also used in telecommunications systems and electric vehicle charging systems, among others.

To ensure the proper operation and long-term effectiveness of the 2027-35-ALF surge protector, regular maintenance should be performed on the device. This involves checking the trip contact for any oxidization or corrosion, testing the sensitivity of the device, and verifying the presence and condition of the stainless steel case. In addition, the gas chamber should be checked and filled, if necessary, to ensure that it is operating properly.

The 2027-35-ALF GDTs are an important part of any electrical system, providing necessary protection from transient events for the system and components. With proper monitoring and maintenance, these devices can provide reliable protection for a long period of time, ensuring the safety and performance of the system.
