Boarden produces gas discharge tubes, which are widely used electronic components for overvoltage protection. These discharge tubes come in two types: diodes and triodes. The voltage range of these tubes varies from 75V to 3500V, with over one hundred different specifications available to meet the needs of various applications. All products are manufactured, monitored, and managed strictly according to CITEL standards, ensuring their reliability and consistency.
Gas discharge tubes are commonly used in the first or first two stages of multi-level protection circuits. Their primary function is to divert transient overcurrents caused by lightning and limit overvoltages, thereby protecting subsequent circuits from damage. They play a crucial role in the protection of communication lines, power systems, and other equipment that requires lightning protection.
The operation of gas discharge tubes is based on the gas discharge phenomenon. When the applied voltage increases and exceeds the insulating strength of the gas, the gap between the two electrodes will break down, causing the gas, which was initially in an insulating state, to become conductive. Once the discharge tube conducts, the voltage between the two electrodes is maintained at a lower residual voltage level determined by the discharge arc, effectively limiting the overvoltage.
