Reliability in Surge Protection AC power line Photovoltaic system High frequency coaxial line Telecom and data line Gas discharge tube www.citel2cp.com CITEL, the company Etablished in 1937, CITEL-2CP is the leader in France for Surge Protection Devices (SPD, TVSS...). In addition to the hundred of thousands of modules manufactured, CITEL2CP is also oldest in the world for the manufacturing of Gas Discharge Tubes (GDTs, protection for fixed telecom lines, modems, medical equipment etc...). • • • • SPD and GDT manufacturer for several decades International sales > 80 % Subsidiaries in Germany, USA, China, Russia, India Internal Test Laboratory “Lightning” (100 kA @10/350µs) Our goal is to provide efficient and standard-compliant solutions in order to ensure maximum performance and reliability of our surge protectives devices. Our objective : to protect your equipment against overvoltages Various causes of transient overvoltages Mainly caused by lightnings, transient overvoltages (several kilovolts during a few microseconds) brings about important consequences in every network (AC, DC, Telecom, Data, RF). They may create disturbances, losse of data and even the full destruction of sensitive equipment. Direct strike Coupling Strike on overhead lines Earth Potential rise Protecting your installation will allow you to : • • • • • Increase your productivity Limit discontinuities of service and their costs Increase the life duration of your equipments Improve the quality and precision of your process Result : savings + improved quality of service Affected equipment or network The Surge Protection Devices (SPD) SPDs are the only efficient solution against transient overvoltages due to lightning or to switching phenomena. The goal is to limit the overvoltages to a level in compliance with the electrical withstand of the terminal equipment to be protected. The SPD has to : • • • Photovoltaic Radiocom AC Powerline provide the lowest residual voltage as possible, provide a discharge capacity adapted to the real risks, avoid disturbances of operation for the equipment. These parameters will be reached by selecting the relevant surge protectors, as well as installing them in the correct way. Easy to use and efficient, CITEL surge protectors have been designed following the main international standards. CITEL provides a wide range of surge protectors adapted to every network: AC power , DC power, Telecom, Data and RF .

Moreover, the “quarter-wave” technology does not need maintenance. Nevertheless the PRC protectors cannot be used on RF cable with DC power injection (active antenna) and must be carefully chosen in relation with the operating frequency. Equipment “Sparkover” operation DC up to 6 GHz Imax : 20 kA Residual voltage < 300 V Ageing in relation with the number of operations The use of dedicated gas tubes allows a very large bandwidth to the P8AX surge protectors (from DC to 6 GHz). Due to very low insertion losses and excellent VSWR, these units can be used on all kinds of RF lines, even in case of DC power injection (e.g.active antenna). For a fast and easy maintenance, the internal gas tube is replaceable.
