Gas discharge tubes (GDTs) are an essential component of the surge protection device. They provide a low-impedance path and clamp the overvoltage to the desired level. The GTCS28-900M-R20 is a GDT with lead three-phase arresters, one-end triple-pole connection, and rated current of 20kA. It is designed for protecting traction equipment in railway, metallurgy, lifting and automatization system.

Customer benefits of using the GTCS28-900M-R20 GDT include a reduction in the surge voltage due to its rated current of 20kA, improved system reliability and longer service life. In addition, the GDT is resistant to environmental impacts and has a different insulation level, which enables it to operate in a variety of applications with different environmental conditions.

The working principle of the GTCS28-900M-R20 GDT is based on the capacitive division of the waveform. It suppresses normal overvoltages and is used to protect against surge voltages that could potentially damage the insulation of electrical equipment. When the voltage rises above the rated voltage, the gas tube will turn on and provide a low-impedance path to divert the excess voltage. As a result, the peaks of the waveform are decreased and the load voltage is safely clamped.

Installation and set-up of the GTCS28-900M-R20 GDT are simple, and the device can be easily connected to existing power systems. In addition, the GDT can be integrated into existing systems without the need for additional components. The device is designed for use with two-wire or three-wire systems, and is suitable for use in traction, heat and air conditioning systems, and automotive applications.

Overall, the GTCS28-900M-R20 GDT is an ideal choice for protecting traction equipment from overvoltage surges. The device is designed to deliver reliable protection and can be easily integrated into a variety of systems. Additionally, the GDT is resistant to environmental impacts and has a rated current of 20kA to effectively reduce voltage surges.
