Cortem electrical components Germany Cortem model Cortem price

Cortem electrical components refer to lightning arrestor tubes or antenna switch tubes used for overvoltage protection, which contain two or more electrodes and are filled with a certain amount of inert gas. A gas discharge tube is a gap-type lightning protection component used in the lightning protection of communication systems. Gas discharge tubes are gap-type lightning protection components that have been widely used in the lightning protection of communication systems. Discharge tubes are often used in the first or first two stages of multi-stage protection circuits to discharge instantaneous lightning overcurrents and limit overvoltages. Due to the inter-electrode insulation resistance of the discharge tube
