Graphite resistivity reducer is a powdered grounding material composed of high-grade microcrystalline graphite, along with膨润剂, adsorbents, electrolytes, and other materials. It is a physical type of resistivity reducer, with all its components simultaneously adsorbing moisture and toxic ions around, thereby purifying the surrounding soil environment. Hence, it is an environmentally friendly new type of grounding material.

Graphite resistivity reducer features:

High conductivity

To achieve excellent resistance reduction, the material's resistivity must be low. The Guodian Tianbang series of physical graphite resistance reducer is made from non-metallic conductive materials, relying on the dense electronic connections of the conductive materials and is unaffected by moisture. This graphite resistance reducer, which relies on the electronic conduction mechanism, is particularly suitable for desert and arid, rainless mountainous areas. Even when moisture is dispersed, the resistivity remains low, ensuring a significant resistance reduction effect.

High mechanical strength

Graphite resistance reducer utilizes a gradation of different materials, mixed with water and applied to the grounding body. Under natural curing conditions with backfill, the compressive strength of the graphite resistance reducer reaches 10MPa. Its high mechanical strength has a similar effect to concrete, protecting the grounding body from rain erosion and to a certain extent preventing theft. These features hold practical significance in rugged mountainous线路 areas.

3. Excellent performance

Chemical graphite resistivity reducer can cause corrosion to steel grounding bodies due to the release of ions, especially chloride ions. The soil has significant heterogeneity in its physical and chemical properties. Additionally, some resistivity reducers made of graphite without strength (cannot solidify) may not be tightly packed around steel grounding bodies, allowing moisture, oxygen, microorganisms, and others to penetrate and cause corrosion. The second point mentions that the Guodian Tianbang series of physical graphite resistivity reducers have the properties of concrete, becoming solid and dense after construction and curing, thus preventing steel corrosion. Moreover, the SUPERWELD series of physical graphite resistivity reducers have a high pH value, which can resist corrosion from many acidic ions. The good corrosion resistance of the steel reinforcement in concrete is due to this reason. The Guodian Tianbang series of physical graphite resistivity reducers also contain corrosion inhibitors to protect the grounding bodies.
