Features and advantages
1. Unique manufacturing process: using cold rolling and hot drawing production technology to achieve metallurgical fusion between copper and steel. It can be pulled freely like pulling a single metal, without detachment, warping, or cracking.
2. Superior corrosion resistance: The composite interface adopts high-temperature welding, with no residue and no corrosion phenomenon on the joint surface; The surface copper layer is thick (with an average thickness greater than 0.3mm), has strong corrosion resistance, and has a long service life (greater than 30 years), reducing the intensity of maintenance labor.
3. Better electrical performance: The excellent conductivity of the surface copper material makes its own resistance value much lower than conventional materials.
4. Widely safe and reliable: This product is suitable for grounding construction under different soil moisture, temperature, pH value, and resistivity changes.
5. Safe and reliable connection: using dedicated connecting pipes or hot melt welding, the joints are firm and stable.
6. Easy and fast installation: With complete accessories and convenient installation, it can effectively improve construction speed.
7. Improve grounding depth: With a special connection transmission method, it can penetrate up to 35 meters underground to meet the low resistance requirements of special occasions.
8. Low construction cost: Compared to the traditional construction method of using pure copper grounding rods and grounding strips, the cost has been significantly reduced.
Technical Specifications
1. Copper layer thickness ≥ 0.3mm
2. Tensile strength ≥ 600N/mm
3. Flatness error ≤ 0.5mm/m
4. Copper layer plasticity: When the grounding rod and grounding round wire are bent at 30 degrees, there are no cracks on the inner and outer edges of the bend.
Copper layer adhesion: After adhesion test, except for tigerThe copper layer on the jaws of the pliers has peeled off, and the restPart of the copper and steel are well bonded, but peeling phenomenon may occur.
