Gas Discharge Tube Arresters (GDTs) are protective devices that protect sensitive electronics and electrical wiring from lightning-induced damage, such as voltage spikes, transients, and surges. GDTs are housed in a metal cylinder and contain a filling of various gases and a dielectric material, such as quartz, that lines the interior of the cylinder. When lightning strikes or electrical power is disrupted, the dielectric material in the GDT breaks down, allowing the charge to pass through and be absorbed into the gas, which is then dissipated safely away from sensitive electronic components.

The 2027-35-BT1 GDT Arrester is a 3-pole, 350 mm (14") long angle-valve gas discharge tube arrester. It is designed for medium-voltage applications that are able to withstand up to 5 kilovolts (KV) of electrical current. The 2027-35-BT1 is UL recognized for up to 8.3 KV of surge insulation and over-voltage certification. The 2027-35-BT1 also features a large diameter brass body, meaning that it can absorb more energy, and consequently provide superior protection from voltage surges. The 2027-35-BT1 GDT Arrester has an allowable leakage current of <1mA under normal operating conditions. The 2027-35-BT1 is an excellent option for power conversion and distribution applications, and in some cases, can be used in conjunction with other GDTs for added protection.

The 2027-35-BT1 works by reducing the voltage in high transient surge situations. When a surge of electrical power is detected, the 2027-35-BT1 GDT Arrester will absorb the excessive energy and decompose it into harmless levels of current. This is made possible by the construction of the GDT, which utilizes the gases within the arrester allowing it to absorb the excessive energy, rather than allow it to surge into the protected equipment.

In order for a GDT to operate correctly and absorb the electrical surge as intended, the 2027-35-BT1 must be mounted properly. It should be installed within 6 inches (15 cm) of the protected equipment or on the main power distribution lines to the equipment. The goal is to ensure that the 2027-35-BT1 GDT Arrester is the first device to experience the surge, thus preventing it from entering the system and damaging the electronics.

The 2027-35-BT1 GDT Arrester is an excellent choice for medium-voltage applications, and is designed to protect sensitive electronic equipment from lightning-caused surges of energy. Through its ability to absorb the surge, the 2027-35-BT1 GDT Arrester ensures that the components of an electrical system are not damaged in the event of a power disruption or lightning strike. The 2027-35-BT1 provides superior protection with its large diameter brass body, which can absorb more energy than smaller GDTs, and its low leakage current rating. Additionally, it requires proper installation in order to function efficiently.
