Gas Discharge Tube Arresters (GDTs) are an important part of a power system and in many ways play a protective role. They are also called lightning arrester, surge protector, or surge diverters. The purpose of a GDT is to divert lightning and other high-energy surges away from delicate electronics and power systems. GDTs can protect a power system from lightning strikes, line surges, and other electrical disturbances caused by sudden changes in voltage.

One type of GDT, the 2026-25 CBLF arrester, is designed to protect high-voltage AC circuits such as electrical distribution systems, industrial equipment, and medical equipment from high-energy transient events. The CBLF series of GDTs use a spark gap to detect high-energy surges and divert it away from the protected equipment by quickly discharging the energy into a grounding conductor. This type of GDT operates as follows: when a high-energy surge or transient event passes through the spark gap, the voltage rises high enough to create a spark, breaking down the gas inside the GDT. This spark acts as a short circuit and diverts the energy away from the protected circuit.

The CBLF GDTs have several advantages, including excellent noise protection, high voltage stability, high temperature and humidity resistance, and an easy-to-install design. They are also self-resetting, so they will not require replacement after each protective event. Additionally, CBLF GDTs are designed to operate in temperatures ranging from -10°C to +50°C and a humidity range of up to 95%.

The CBLF GDTs can be operated in either manual mode or automatic mode. In manual mode, the GDT is triggered by a switch and can be reset manually. In automatic mode, the GDT will activate when a high-energy surge is present in the line and will reset automatically when the surge dissipates. This makes the GDTs well-suited for use in applications where high-energy transients are common, such as industrial equipment, medical imaging equipment, and automotive systems.

The 2026-25 CBLF GDT is designed for use with AC electricity and is rated for voltages of 15kV and below. It has a nominal discharge current of 10kA, a voltage safety margin of up to 6.14kV, and a maximum voltage of 20kV. It is UL and CSA listed, which indicates that it has been tested for safety and reliability. It also has a life expectancy of more than 100 years, making it a durable and reliable choice for protecting delicate electrical equipment.

In conclusion, the 2026-25 CBLF gas discharge tube arrester provides reliable and durable protection for AC circuits from high-energy transient events. It features high voltage and temperature stability, high humidity resistance, easy installation, and a long life expectancy. The self-resetting GDTs can be used in both manual and automatic modes, making them a great choice for use in industrial and medical applications.
