Copper plated steel grounding rods by electroforming technology special 99.9% copper uniform converage to the low carbon steel core,copper and steel core completely molecules (such as combination does not close, in the case of electricity, will produce the original battery reaction,anode metal iron oxidized into iron loss,but speed up the steel core by corrosion).It has a thick copper layer (0.25mm),the adhesiveness is good,not peeling (rolling thread) etc.It has the advantages of high tensile strength (up to 600N/mm2), strong corrosion resistance (which can ensure the service life of more than 30years),with stable low resistance and good plasticity,with the same performance as copper and together with feature of steel.

Copper plated steel grounding rods,buried deep underground in both natural corrosion or electrochemistry reaction, it has strong protection alibity.Grounding rods and earthing connections with hot-melt solder our production of welding, the grounding device is completely under the protection of copper,a maintenance free earthing device real.

Copper plated steel grounding rod is equipped with a coaxial connector, and the driving head drill kit. According to the different geological and use requirements can be achieved by the use of brass coaxial connector (bolt) connection, arbitrarily increase the length of copper plated steel grounding rods. The top drive head (the connecting bolt connection for use with blow), deep. Terminal adopts specially made drill (bolt) connection, to facilitate the bastinado deep.

Product features

1. Copper and steel bar continuous molecular perfect combination: composed of a solid core of cold drawn steel car, plating a layer of nickel, plating thickness of copper in nickel layer, due to nickel and copper and steel has good bonding properties,so as to ensure the perfect combination of the copper layer and the steel core.
2. Combined with copper and steel core is perfect,the surface of copper layer with 25times the magnifying glass to detect no loopholes.
3. Superior anti-corrosion performance,surface with thick copper layer (average thickness equal to or greater than 0.254mm),strong corrosion resistance, the service life is expected to exceed 40 years,reducing the labor intensity and cost of maintenance.
4. Better electrical properties:excellent conductive properties of surface copper material,make its resistance value is much lower than that of conventional materials.
5. The use of a wide range: ground built this product is suitable of different humidity, temperature, PH value and the resistivity change conditions.
6. The construction is convenient and fast,and can manual or the use of mechanical construction,minimally invasive operation,greatly improving the efficiency of the construction.
7. High strength,suitable for drilling deep 35 meters underground,the copper layer is not broken,do not fall off,in order to meet the special occasions of low resitstance requirements.
8. Low cost:the construction method using pure copper grounding rod,ground,cost is greatly reduced.(and has the strength of steel,cooper grounding bar cannot reach)

Related tests

1. Adlesion test: the lathe cutting,made of copper plated steel surface to the internal cutting,which is smaller than original diameter of 1mm turning to exposed copper layer and steel rods, outsourcing copper layer without peeling phenomenon.
2. Bending test: the sample length is 40 times the diameter of the copper plated steel,the tiger clamp the bent 30°, copper layer without peeling,no wrinkles.
3. Tensile test: tensile strength of plated steel rods of copper up to 600N/ mm2.

Mechanical hammer

Power-driven impact hammer can be used when the rod cannot be piled into the ground or piled into depth by hand under hard soil environment.

Selection of drill holes

It is necessary to use drilling tools when it is really difficult or impossible to pile into desired depth.

Insert the ground rod into the hole and then inject the water-containing resistance-reducing agent.
