About us

For over 75 years, we have developed and manufactured the Ceramic Gas Tube Surge Arrester (Gas Discharge Tube or GDT). Aolittel gas tube arresters protect personnel, equipment and circuitry from abnormally high voltages caused by lightning or electrical transients. Our surge protection devices have well defined surge-limiting characteristics enabling them to spark over (or breakdown) when the abnormal voltage on a line reaches a specific level. When sparkover occurs in the GDT, the surge is redirected to earth. Aolittel's gas tube arrestors are known for their quality. Throughout the world, products from our factories provide protection for equipment and personnel.

Description

A gas-filled tube, also known as a discharge tube, is an arrangement of electrodes in a gas within an insulating, temperature-resistant envelope. Gas-filled tubes exploit phenomena related to electric discharge in gases, and operate by ionizing the gas with an applied voltage sufficient to cause electrical conduction by the underlying phenomena of the Townsend discharge. A gas-discharge lamp is an electric light using a gas-filled tube; these include fluorescent lamps, metal-halide lamps, sodium-vapor lamps, and neon lights. Specialized gas-filled tubes such as krytrons, thyratrons, and ignitrons are used as switching devices in electric devices.

The voltage required to initiate and sustain discharge is dependent on the pressure and composition of the fill gas and geometry of the tube. Although the envelope is typically glass, power tubes often use ceramics, and military tubes often use glass-lined metal. Both hot cathode and cold cathode type devices are encountered.
