99.9% Copper Steel Wire Spool for Grounding Rod (IEC, UL Listed)

99.9% Copper Steel Wire Spool for Grounding Rod (iec, ul Listed)

Description

Copper clad steel grounding conductor has better mechanical properties, corrosion resistance, electrical performance and life cycle. In large area grounding or long distance grounding, the length of copper clad steel rod is less than 6 meters, in large area horizontal laying, it needs to be connected every 6 meters, a huge number of welding joints will cost many man-hours, which will increase the project time and material cost. According to this shortcoming, Sunlight has developed 100m/roll copper clad steel round wire (customized available).

Tensile strength:

350-770 MPa (for vertical grounding); 290-510 MPa (for horizontal grounding)

Copper thickness:

0.254 mm-0.8 mm (custom order is available)

Ductility of copper layer:

When the product is continuously bent by 90° three times, no cracks will occur on the inner and outer edge copper layer.

Weldability of copper layer:

When the product is placed between the clamp or vice jaws, the distance between which is less than the diameter of the steel core of the sample (W=d-0.1), hit the end of the sample with a hammer, cut off a sufficient layer of copper, completely expose the steel core, the peeled copper layer is allowed on the vice jaws, but the remaining part of the rod, peeled copper and steel should not be visible to the naked eye.

Electrocorrosion characteristics:

when simulating the short-circuit current interruption after the electrocorrosion resistance test, the final resistance growth rate does not exceed 50% of the initial resistance value. Moreover, the resistance growth rate at each stage of the test does not exceed 15% during the test. The surface of the copper-coated steel sample after the test is solid, without cracks, cavities, and defects in the form of bubbles.
