Anti-corrosion grounding materials are a new generation of grounding products developed by me based on the market development needs of the lightning protection industry. In order to effectively solve the anti-corrosion and conductive problems of the ground network, this product uses nanocarbon anti-corrosion grounding materials. It is a new generation of anti-corrosion conductive grounding material developed on the basis of nickel powder and graphite anti-corrosion conductive coating. Using nanocarbon as a conductive additive, it has stronger conductivity and anti-corrosion than graphite powder and nickel powder anti-corrosion conductive agent. It is a kind of nano-carbon with very strong conductivity and resistivity close to that of ordinary metals. Nano-carbon serves as a metal grounding body and soil The medium between them will not affect the spread of impulse current. Nanocarbon has excellent high temperature resistance and will not fall off when encountering the impact of a relatively strong current. The nanocarbon anti-corrosion grounding body has good anti-corrosion properties: for acidic grounding environments, the nanocarbon grounding body uses alicyclic amine as the curing agent, which greatly improves the acid resistance of the coating. For alkaline soil, the curing of the resin is After chemical reactions such as condensation, ring closing, addition or catalysis, the thermosetting resin undergoes an irreversible change process. Therefore, the anti-corrosion performance of the nanocarbon grounding body is more superior. Excellent surface bonding performance: The nanocarbon grounding body coating uses epoxy as the base material. Since its molecular structure contains epoxy groups and ether groups, it has inherent high adhesion properties, so the nanocarbon and the grounding body will not interact. Strip.

Copper-clad steel strand copper-clad steel (copper-clad steel) is copper-clad steel core. In fact, the surface of the steel core is evenly covered with a certain thickness of pure copper metal composite wire. It uses the skin effect principle of low-voltage and high-frequency signals to walk along the surface in the high-frequency area. Therefore, as long as the copper layer reaches a certain thickness range, the signal in a certain frequency range can be guaranteed to be transmitted. The role of copper is to conduct weak electrical signals; the role of the steel core is to support. Traditionally, steel-clad grounding wires generally use pure copper wires or galvanized steel, but the conductivity and service life of galvanized steel are far less than those of pure copper wires. However, the disadvantage of pure copper wire is its high cost, which is not as affordable as galvanized steel. Therefore, the new copper-steel composite conductor can not only carry good electrical conductivity like pure copper wire, but also have the strength of rigidity, and greatly reduce the cost. According to the skin effect, when the copper layer on the surface of the ground conductor reaches a certain thickness, the steel core intercepts the current very little and can successfully replace the pure copper wire. This product not only has the characteristics of steel such as strength, toughness, resistance to sudden changes in temperature differences, and resistance to pressure, but also has the advantages of corrosion resistance, high conductivity, and anti-oxidation of copper. On this basis, it also extends its service life and reduces costs. . Therefore, this product is an updated product of high-tech products. Compared with traditional copper stranded wires, this product has the advantages of low density, high strength, and low cost, but its working efficiency is equivalent. According to the different methods of wrapping copper onto the surface of the steel core, it is mainly divided into electroplating, cladding, hot casting/immersion and electroforming processes. According to the copper-clad steel currently on the market, the electroplating process is widely used, which uses the working principle of electrolytic cells to fully dissolve the copper and then guide the current to cover the surface of the steel core; what about the cladding method? That is to wrap the copper strip around the steel core, and use argon arc welding at the wrapped interface; hot casting/immersion is to heat and melt the copper into a liquid, cover it on the surface of the steel core, and cool and solidify after a certain period of time. According to different strengths, copper-clad steel can be divided into: soft A, semi-hard M, hard HS, and super-hard EHS. According to different wire diameters, it can be roughly divided into: (below 0.2) center wire), large wire), Thick wire and above) Application scope: This product has been widely used in lightning protection grounding, anti-static grounding, protective grounding and other work in petrochemical, railway, electric power, airport, network communication and other places.

The more bound charges are generated. Bound charges also generate an electric field, which always weakens the external electric field. When filling the dielectric, due to the polarization of the dielectric, bound charges appear near the surface of the dielectric. Correspondingly, the free charges on the plate also increase accordingly. That is, after filling the dielectric, the plate accommodates more free charges, indicating that the capacitance is increased. Therefore, the relative permittivity of the dielectric is always greater than 〖. For example, mica=polystyreneer=5. The dielectric constant of insulating materials changes due to factors such as power frequency, temperature, humidity, etc. As the temperature increases, the dipole steering polarization is easy to proceed and the dielectric constant increases. However, when the temperature exceeds a certain limit, due to the intensification of thermal motion, the polarization becomes more difficult and the dielectric constant decreases.
