Gas discharge tube arresters (GDT) are semiconductor devices used to protect electrical circuits from damage caused by the effects of lightning and other transient events. They are designed to detect and arrest high voltage spikes, such as those caused by lightning, by controlling the flow of current through the device. GDTs work by temporarily grounding high surge currents, thereby acting as a protective barrier between the source of the surge and the protected equipment.

A GDT is composed of two electrodes, called electrodes A and B, that are separated by a dielectric material, typically an insulating ceramic. Electrodes A and B are arranged in an alternating pattern, with electrode A connected to the positive side of the power supply while electrode B is connected to ground. When a surge occurs, electrons flow from the positive terminal through electrode A and to the negative terminal through electrode B, effectively grounding the surge and protecting the circuit.

2018-50-SMH-RPLF are low-voltage surge arresters designed to protect telecommunication equipment from transient overvoltage faults caused by lightning. This product is designed to protect components like line cards, coaxial cables, and other sensitive equipment like radios and routers against voltage surges. The maximum surge ratings for the 2018-50-SMH-RPLF are 10kA/10kV (10kA/3000V) peak and 2kA/20kV (2kA/8000V) peak, with a maximum series resistance of 0.25 Ohm.

The working principle of the 2018-50-SMH-RPLF is based on the temporary disconnection of the power line from the ground, allowing the voltage surge to be absorbed by the arresters. The energy is then dissipated in the form of heat or light, depending on the type of arrester. The high voltage arrester will provide protection for the connected equipment even when it has been subjected to a lightning strike.

The 2018-50-SMH-RPLF gas discharge tube arresters are designed for telecom equipment, such as radio repeaters, to protect them from the damaging effects of lightning and other transient events. The product is designed with a series of electrodes that are connected in an alternating pattern, allowing for the passage of current from the positive side of the power supply to the negative side via the electrodes when a surge occurs. The surge is absorbed by the arrester, which then dissipates the energy in the form of heat or light.

The 2018-50-SMH-RPLF gas discharge tube arresters are an efficient and reliable solution for protecting telecom equipment from the damaging effects of transient events. With a maximum surge ratings of 10kA/10kV (10kA/3000V) peak and 2kA/20kV (2kA/8000V) peak, and a series resistance of 0.25 Ohm, these gas discharge tube arresters provide an effective solution for protecting telecom equipment from harmful voltage surges.
