A black and gray mineral composite material with excellent electrical conductivity.
The physical resistivity reducer's composition includes a large amount of semiconductor elements and metal compounds such as potassium, calcium, aluminum, iron, and titanium. These metal compounds not only possess excellent conductivity but also provide good cathodic protection for grounding equipment. After absorbing water and swelling, they are surrounded by a network colloid, and the spaces within the colloid are filled with partially hydrolyzed colloids, preventing these elements from being washed away by groundwater and rain. This ensures that the conductivity of the resistivity reducer is consistently maintained, with active ions moving and permeating into the surrounding earth.
Physical resistance reducer effectively addresses the technical challenge of electrical path resistance and contact resistance, solving complex lightning protection grounding and protective grounding engineering issues under various geological conditions. It can ground in large areas with strict engineering requirements and equipment resistance requirements less than 0.5-1Ω, ground under conditions of severe corrosion, ground in rocky and desertic dry geological conditions, and ground in narrow areas within urban areas limited by space.
Physical Resistance Reducer Product Features:
1. Excluding corrosive electrolytes can enhance the performance of metal electrodes; their conductivity is not limited by acidic, alkaline, saline conditions, or temperature and humidity.
2. Non-dissolving excellent conductor; its conductivity is not reduced due to falling groundwater levels or dry weather, nor does it lose conductivity with excessive rainfall.
3. Excellent uniform pressure action, which can even out potential distribution, thereby reducing step voltage and protecting personal safety.
4. Extreme cold resistance, high-pressure impact tolerance, long-term stability, service life over 30 years.
5.常态下, it is a light black solid powder.
Principle of physical resistivity reducer:
1. The resistor is a physical resistor, primarily composed of graphite, a good non-metallic conductive material, along with various additives. START resistor contains stable conductive ingredients, chemical electrolytes, metal passivation rust inhibitors, and other components.
2. The resistivity reducer is applied between the metallic grounding body and the soil, tightly surrounding the metallic electrodes. On one hand, it ensures close contact with the grounding body and soil, expanding the area of conduction and reducing the contact resistance between the metallic grounding body and the soil. On the other hand, by渗透 into the surrounding soil and rock crevices, it forms a root-like network, creating a low-resistance, gradually changing area around the grounding electrode, lowering the resistivity of the surrounding soil, and significantly reducing the overall grounding resistance of the ground grid.
3. The resistance reducer contains metal passivator, which can钝ize the surface of the metallic grounding body, prevent rusting, and prolong the service life of the grounding body. The reducer maintains the soil around the electrodes in a moist state for a long time, preventing the grounding resistance from being affected by climatic changes during dry seasons, thereby ensuring good stability.
