Copper-Clad Steel Grounding Electrode/Earthing Rod-Advanced High-Efficiency Grounding And Resistance-Reducing Materials
I.Product Introduction
Copper clad steel grounding rod,the introduction of advanced technology from France,using a unique production process.The product also combines the low resistance of copper,strong corrosion resistance,good electrical connectivity,as well as the high strength of steel,construction convenience and other characteristics,is the best choice to replace the traditional metal grounding materials.The product adopts French advanced electroforming technology,copper layer into one,has good plasticity,can be rolled thread,can be bent,transport and construction is convenient,can be widely used in power transmission,power stations,communication base stations,buildings and antennae grounding devices,and the lightning catcher(lightning rod,lightning conductor)and lead wires to form a lightning protection and grounding system.
II.Product features
French advanced manufacturing technology
Adopting France first-class new copper electroforming technology production,bending 180 degrees will not appear delamination,cracking phenomenon.
Low cost,wide range of applications
Compared with the traditional pure copper grounding rod,the cost is reduced by 70%.Special multi-segment connection method,can be deep underground 35 metres,to meet the requirements of special environmental construction.Suitable for any project,the application is very wide.When used with flexible grounding technology,it can greatly reduce the length of deep wells and save construction costs.
Strong anti-corrosion characteristics
Oxygen-free copper layer on the surface(up to 0.256~0.5),strong corrosion resistance,suitable for different PH value,resistivity,humidity,temperature of the soil environment,service life of more than 30 years.
Easy construction
WM exothermic welding or wire clip fixing method of connection,fast and simple,solid joints,good stability.
Obvious resistance reduction effect
Oxygen-free copper surface material is highly conductive,and the resistance reduction effect is significantly better than that of ordinary metal materials.
III.Product specification
Example:HD-Φ14.2 means the diameter of grounding rod is 14.2mm.
It means that both ends are threaded.If there is no marking,it means one end is pointed and one end is flat.
Note:The above models are all pointed at one end and flat at the other;if you need both ends with threads,please specify before placing an order.
IV.The technical test
1、Tensile strength:≥600N/mm².
2、Copper layer bonding:After the adhesion test,the rod body copper-steel bonding is good,there is no stripping phenomenon,vise jaws jaws bite a little flaking copper layer,is a normal connection wear.Can be required length through the connection sleeve to lengthen the grounding rod,deep underground 35 metres,to reduce the impact of climatic conditions(such as frost and drought)on the soil resistivity and grounding resistance.
