CG75L is a member of the Gas Discharge Tube Arresters (GDT) family, a family of protecting devices used for electrical and electronic equipment from voltage transients and electrostatic discharges caused by lightning and other transients. CG75L is unique in its use of a gas fill between two electrodes, which limits the arrester\'s current through a transient absorbing element. The working principle behind the CG75L GDT arrester is relatively straightforward. In normal operating conditions, the arrester will remain in its open state, allowing current to flow freely; however, when a surge or spike in current occurs, it activates the arrester mechanism. This occurs when the voltage across the arrester exceeds a predetermined level, usually between 90 and 1000 volts. When this happens, the gas fill between the electrodes expands, compressing the upper dielectric and forming a spark gap, limiting the current to a predetermined level. The increased number of electrons then forms a spark channel, which is then discharged as a single flash event. The advantages of CG75L GDT arrester is that it is a stand-alone unit, eliminating the need for a grounding system to reduce or prevent overvoltages. GDT arrester also has a low-resistance path that serves as an extremely fast protection against high-voltage surges and electrostatic discharges. They are also highly reliable, with a lifespan of up to 20 years. Their low installation and maintenance costs make them an attractive choice for protecting sensitive electronic equipment. In terms of usage, CG75L GDT Arresters are mainly used in industrial applications such as power stations, substations, telecommunications sub-stations, telecommunication exchanges, railway crossing clamps, lightening rods and broadband transmission networks. Their ability to provide high-speed protection from high-voltage surges and electrostatic discharges make them highly suitable for these tasks. Additionally, the low cost and high reliability of CG75L GDT Arresters make them a perfect choice for residential applications as well. In conclusion, the CG75L GDT Arresters provide a highly reliable and cost effective solution for protection against voltage transients and electrostatic discharges. Their easy installation and long lifespan make them the perfect choice for applications such as power stations, lightening rods, broadband transmission networks, and residential residences.
