Product Introduction
Jichangdi brand CD series copper-clad steel ground rods are made of high-quality low-carbon steel with a carbon content of 0.10%-0.30%. The high-conductivity electrolytic copper is uniformly covered on the round steel surface with a thickness of 0.25 －0.5mm, this process can effectively slow down the speed of ground rod oxidation in the ground. This ground rod can be divided into two types: single and combined. The single rod can be pointed at one end and flat at the other end, and can be threaded on the roll with each pointed end. The two ends of the combination need to be threaded on the roll. The thread is processed by the roll thread groove, which maintains the tight connection between steel and copper, ensures high strength, and has excellent electrical grounding performance. This product has been widely used in the grounding system of electric power, petrochemical industry, transportation, civil construction, and large-scale mechanical equipment. It has the characteristics of long service life, economy, and excellent electrical conductivity.
Structure
Main rod: The ground rod is made of high-quality cold drawn element steel, and is cast with red copper (thickness 0.3~0.5MM, copper content 99.9%) with special equipment to ensure its excellent electrical conductivity and mechanical strength. This product has excellent Anti-corrosion performance.
Connecting pipe: A copper connecting pipe can be used to connect the rods, which has a better anti-corrosion effect. The rod is in close contact with the rod, and the driving force directly acts on the ground rod when the ground rod is driven into the ground or when the driving drill is used to drill into the ground. Divided into threaded connection and non-threaded connection.
Drive head: It is made of high-strength alloy steel, which can ensure that the drive force goes underground smoothly.
Alloy tip: to ensure penetration into the ground under complex geological conditions.
Application
Copper-clad steel grounding materials are suitable for general environments and special environments where damp, saline-alkali, acidic soil and chemically corrosive media are produced. They are widely used in power plants, substations, transmission line towers, communication base stations, airports, railways, subway stations, and various Lightning-proof grounding, anti-static grounding, protective grounding, work grounding, etc. in high-rise buildings, microwave relay stations, network computer rooms, petrochemical plants, oil storage depots, etc.

6 | Production Process | The four-dimensional electroplating method adopts the domestically pioneered nano alkaline copper pre-plating technology. The principle is to finely control the density and deposition speed of nano-scale particle clusters formed by complexes and Cu2+ in the plating solution by constructing an aerodynamic field environment, and construct a new type of nano-scale particle deposition model between mace and steel, cathode The metal deposition forms a nano-scale alkaline copper particle crystal coating structure. The nano-scale crystal coating has good compactness and a highly activated surface, which greatly enhances the affinity between the coatings and makes the product binding force reach the standard. The finished product has excellent mechanical strength, ductility and corrosion resistance. |
