Product Details

Copper bonded/clad steel grounding tape(IEEE837,IEC62561,UL certification)

Through a large number of copper bonded steel applications in projects, such as power plants, substations, petrochemicals,etc., we found that the copper bonded steel rods cannot meet the large grounding area and the long distance grounding requirement. The length of general copper bonded steel rod is less than 6 meters, when laying a large area horizontally, it needs to be connected every 6 meters, the huge number of welding joints will cost a lot of man-hour, which will increase the project time cost and material cost. According to the weakness, Sunlight Company have developed copper bonded steel round wire and copper bonded steel tape with a length of 100 meters in coil, which contains all the physical properties of the copper bonded steel ground rod and the length advantage of the copper bonded steel strand, to meet the needs of different places in the project.

Technical parameter of Sunlight copper bonded steel

1.Tensile strength :Rm 600Mpa Yield/tensile ratio:0.85-0.90

2.Copper thickness: H 0.254mm

3.Plasticity of copper layer: When the product is bent at 90° there's no crack in the inner and outer edge copper layer.

4.Copper layer bondability: When the product is placed between the clamp or the vise jaws, the spacing is smaller than the diameter of the sample steel core(W=d-0.1),hammer the end of the sample, cut off enough copper layer, fully expose the steel core, the exfoliated copper layer is allowed at the jaws of vise, however the remaining part of rod, exfoliated copper and steel is not allowed to be visible to the naked eye.

5.Electrical-corrosion performance:Simulated fault current releasing, after the electrical-corrosion cycle test, the final resistance value growth rate does not exceed 50% of the initial resistance value, Morever, the resistance growth rate of each test step does not exceed 15% during the testing process, And the surface of the copper bonded steel sample is completed, without cracks, pits,bubbling defects after the test.

Performance testing and matching requirements

In terms of copper bonded steel product application technology, by analyzing IEEE837, IEC62561-2, UL467 and other standards, Sunlight experimental center is equipped with test equipments for all testing, including mechanical testing ,electrical testing, corrosion testing ,ect., for product development and production quality control.

(you can see in the above video image: copper bonded steel produced by other manufacturer cannot pass the fault current test, once the current flows, it melts )

Advantages of copper bonded/clad steel earthing tape coil

1,Copper bonded steel tape coil with a single 100-meter roll( also provide 40-meter, 60-meter, 80-meter roll,etc.,100% suit for market requirements) can be widely used in power plants,substations, petrochemical projects, etc,.

2,Meet the requirements of grounding resistance and potential difference in the grounding system when used in large-scale grounding grid.

3,Reduce direct material cost of the connection joint by 90% and labor cost (eg: The grounding material is laid in a grounding groove with a length of 100 meters, if a single 100-meter copper bonded coil is used, only one connection joint is required, while using a copper bonded steel rod with a length of 6 meters, 16 joints(not including both ends) should be required)
