Made of brass through CNC machining, used for connecting between two grounding rods.

Product Introduction

1. The assembly consists of grounding rods, drive heads, connectors, and drill bits. The grounding rod utilizes a continuous electrolytic plating process to deposit copper ions onto the pre-treated steel core surface, forming a dense molecular bond between copper and steel, resulting in an alloy product that combines the mechanical strength of steel with high electrical conductivity and strong corrosion resistance.
2. Surface quality: The copper layer is smooth and even, without significant defects or other harmful irregularities.
3. Coating thickness: Coating thickness ≥0.254mm; Dimensions: Nominal diameter deviation ≤±0.10mm.
4. Tensile strength: The tensile strength of copper-clad steel is greater than 300MPa, with the fracture location being more than 25.4mm 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?? Ω·m, conductivity ≥20%.
7. Thermal stability coefficient: Thermal stability coefficient C ≥119.
8. Electrical-corrosion performance: After current-temperature cycle tests, freeze-thaw tests, neutral salt spray tests, and fault current impact tests, the final resistance increase is less than 50%, with each intermediate test phase showing a resistance increase of less than 15%. After testing, the surface exhibits 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 might increase soil resistivity and grounding resistance.
10. Soil applicability: Suitable for any harsh soil environments, 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 adaptability to any harsh soil environment for lightning protection grounding applications.
