Product introduction

Description
Ordinary power graphite electrodes use Chinese high-quality Fushun coke as raw materials. Products of the same specification have low resistance and high flexural strength, making them the highest quality products for ordinary power. Below 450 can carry current 8000A-18000A.
Feature
High-quality petroleum coke is used as raw material.
Excellent break resistance.
High resistance to oxidation and thermal shock.
The product has high stability and is not easy to fall off
High mechanical strength and low electrical resistance.
