Product Description

Normal Power Graphite Electrode

Electrical industry does not always use electrical components but also graphite products. Therefore, our company has designed Normal Power Graphite Electrode that is utilized power distribution and stabilizer transformers to control the power supply and endure voltage fluctuations. This Normal Power Graphite Electrode has ideal resistivity, bending strength, and bulk density to remain in shape for numerous years. It also comes in different shapes and variants.
