Description
Technical Data

Overview：

Ultra High Power Graphite Electrodes are a type of electrode that are used in high-power electrical applications. These electrodes are made from graphite and coated with a conductive material such as platinum or gold. The graphite provides a large surface area for electron transfer, while the conductive material allows for efficient current flow. Ultra High Power Graphite Electrodes are commonly used in electrochemical sensors, electroluminescence devices, and other high-performance electrical devices that require precise control over electric potential differences. They are also used in research laboratories to study the behavior of materials under high electric fields.

Description：

Allows the use of current density greater than 25A/cm2,mainly used for ultra-high power steel making electric arc furnace.

UHP graphite electrode is used for the recycling of steel in the electric arc furnace industry. Its main ingredient is high-value needle coke which is made from either petroleum or coal tar. Graphite electrodes are finished with a cylinder shape and machined with threaded areas at each end. In this way, the graphite electrodes can be assembled into an electrode column using electrode nipple.
