Copper-plated steel grounding assembly

Product Introduction

1. The component consists of a grounding rod, drive head, connector, and drill bit. The grounding rod utilizes a continuous electrolytic plating process to coat copper ions onto the surface of a pre-treated steel core, forming a dense molecular bond between copper and steel. This results in an alloy product that combines the mechanical strength of steel with the high electrical conductivity and strong corrosion resistance of copper.
2. Surface Quality: The copper layer is smooth and even, with no significant defects or other harmful irregularities.
3. Coating Thickness: Coating thickness ≥ 0.254 mm; Dimensions: Nominal diameter deviation ≤ ±0.10 mm.
4. Tensile Strength: The tensile strength of copper-clad steel is greater than 300 MPa, with the fracture location being more than 25.4 mm from the fixture.
5. Bending Performance: After bending tests, the copper layer shows no cracks, fissures, pits, or other defects that could impair corrosion resistance.
6. Resistivity and Conductivity: Resistivity ≤ 8.62 × 10⁻⁸ Ω·m, Conductivity ≥ 20%.
7. Thermal Stability Coefficient: Thermal stability coefficient C ≥ 119.
8. Electrical-Corrosion Performance: After undergoing current-temperature cycle tests, freeze-thaw tests, neutral salt spray tests, and fault current impact tests, the final resistance increase is less than 50%. During each intermediate test phase, the resistance increase is less than 15%. After testing, the surface shows no cracks, fissures, pits, blisters, or other defects that could impair corrosion resistance.
9. Grounding electrodes can be connected to the required length and driven up to 30 meters underground, unaffected by climatic conditions (such as frost and drought) that may increase soil resistivity and grounding resistance.
10. Soil Applicability: Suitable for any harsh soil environment, including mountains, rocky terrain, and highly acidic or alkaline conditions.
Product Features: Dense bimetallic structure, excellent mechanical strength, high electrical conductivity, strong corrosion resistance, easy installation without excavation, and suitability for lightning protection grounding applications in any harsh soil environment.
