Tungsten Copper High-voltage Discharge Tube Electrode

Tungsten copper electrode for discharge tube is made of high purity W and Cu powder by isostatic pressing, high-temperature sintering, infiltration, which has excellent conductivity and arc erosion resistance.

During the operation of high-voltage vacuum discharge tubes, the contact material of tungsten copper will experience a temperature increase of several thousand degrees Celsius in just a few seconds. The anti erosion performance, high toughness, and good electrical and thermal conductivity of tungsten copper provide necessary conditions for the stable operation of discharge tubes.

Tungsten's high melting point and hardness lets it resist the temperatures and arc erosion of a tungsten copper high-voltage discharge tube electrode. Since the electrode surface does not suffer extreme ablation and deformation, there is always a high degree of shape and size stability which binds the discharge process and its reliability. Discharge stability also relies on the tungsten copper electrode having strong surface adhesion since copper has a high current distribution ensuring an even current throughout the electrode surface. The furnace's strong current ensures a strong electric field for releasing fused gas ions, ionization, while discharging a pulse. Any further electrode ablation is prevented by the oxide films forming which also extend the electrode lifespan. Protective layers can be relied upon during discharges to withstand extreme arc ablation that diminish abundant gas on the surface. Its thermal expansion coefficient also ensures other discharge tube components remain thermally stress damage safe.

Tungsten copper high-voltage discharge tube electrode plays a key role in high-voltage electrical equipment. In high-voltage switches, as the core component of controlling discharge and turning on and off the circuit, it ensures that the switch can operate accurately and reliably in a high voltage and high current environment to ensure the safe operation of the power system; in lightning arresters, by promptly and effectively guiding lightning current discharge, power equipment and lines are protected from lightning overvoltage damage; in pulse power devices, they are used to generate high-energy and short-pulse electric fields to meet special needs in scientific research, industrial processing and other fields, such as the energy excitation of lasers, the operation of particle accelerators, etc.
