Gas Discharge Tube Arresters (GDT) are devices used to protect circuits from transient high voltage and electrical surges. The technology was invented by Thomas Edison in the late 1800s, and has been continuously improved since then. The C4LF (Contactless Flow Free) technology is an evolution of the GDT technology, which is designed for use in communications/data networks, power systems, and industrial control systems. It\'s used to protect sensitive electronic equipment from overvoltage and transients.The C4LF application field and working principle can be broken down into two main components: the core element and the contactless flow free (CFF) mechanism. The core element is a gas discharge tube (GDT) which contains a high-pressure gas. The gas is ionised by an electrical current which passes through it when a high voltage surge or transient occurs. This causes an arc to form inside the GDT which results in a rapid and extensive reduction of the voltage magnitude and duration. The contactless flow free (CFF) mechanism is designed to ensure the GDT device does not become short circuited by an electrical current that is too great. The CFF mechanism uses a conducting ceramic ring with internal channels that are filled with an insulating liquid. This is placed inside the GDT, and when a high voltage surge or transient occurs, the insulating liquid flows freely inside the ceramic ring. This prevents the current from flowing through the GDT and causing short circuit, thus protecting the sensitive equipment from overvoltage and transients.The C4LF technology is superior to traditional surge arresters as it provides a higher level of protection from transient voltages and electrical surges. Additionally, it is more cost effective than other technologies as it’s much smaller and can be used in more applications and in more places. Furthermore, it\'s highly reliable and durable, with a long service life. It\'s also quick and easy to install, requiring just a single mount that can be installed in minutes. The C4LF technology is becoming increasingly popular in communications/data networks, power systems, and industrial control system industries due to its superior performance and reliability. It can be used to protect a variety of equipment, including telephone and data lines, power system components, and circuit breakers. In power systems, the C4LF can be used in place of Hard-Wired Surge Suppressors, allowing it to be used in a variety of different configurations. Additionally, the insulating liquid used in the CFF mechanism is also flame retardant, reducing the risk of fire damage to sensitive electronic equipment.In conclusion, the C4LF application field and working principle is a cost-effective and reliable technology that is designed to protect equipment from transient voltages and electrical surges. It\'s ideal for use in communications/data networks, power systems, and industrial control systems and is becoming increasingly popular due to its superior performance and reliability. By using this technology, companies can enjoy greater security and peace of mind knowing their equipment is adequately protected from any form of electrical shock or damage.
