BSD Resistance Reducing Agent is made of multiple dominate agent, additive, corrosion prevention agent and solidified agent. It is developed on the basis of research, scientific formula, strict physical and chemical properties test and electric property tests. It has the characteristics of high conductivity, low resistance and excellent negative resistance that resistivity automatically reduces with increase of current density. It has high resistance reduction, more than 50 years effective life, stable property, no toxicity and no corrosion. It is indispensable material to reduce ground resistance for lighting resistance ground rod. It also protects ground rod from acidic and base corrosion.
