Steel Strand/pc Steel Strand

Steel strands are produced through cold rolling and hot rolling to achieve metallurgical fusion between copper and steel. Then ensure the perfect combination of the copper layer and the steel layer, which can be stretched freely like a single metal without breaking, warping, or cracking.

The composite interface of the steel strand is welded at high temperature, with a surface copper layer greater than 0.254mm and no residue, and the joint surface will not show corrosion; The surface copper layer is relatively thick (with an average thickness of over 0.4mm), has strong corrosion resistance, long service life (over 40 years), and reduces maintenance labor intensity.

Compared with the traditional manufacturing method of pure copper grounding rods and grounding plates, the cost of steel stranded wire is greatly reduced. Widely applicable: Steel stranded wire is suitable for grounding under different soil moisture, temperature, pH value, and electrical resistivity changes, with strength that cannot be achieved by pure copper grounding rods.

The steel stranded wire adopts dedicated connecting pipes or hot melt welding, and the joints are firm and stable. Convenient and fast construction: The steel wire accessories are complete, and the installation is fast, which can effectively improve the construction speed. Improving grounding depth: Steel strands have special connection and transmission methods, which can penetrate more than 35 meters underground, meeting the low resistance requirements in special occasions.
