Copper Bonded Round Steel Wire

***Introduction

The Copper Bonded Steel Round Wire are using copper and steel bars made by horizontal continuous casting process, combining copper and steel metallurgy molecules, no electrochemical corrosion and galvanic effect.

As a high-tech grounding lightning protection material, Continuous casting copper bonde steel grounding material have a low difficulty of construction operations, strong corrosion-resistant, excellent electrical properties and other significant advantages for different geological conditions. Especially for coastal pollution of groundwater area, it has excellent value for money.

**Features **

1, the manufacturing process:

The horizontal continuous casting production process: Let steel through a furnace filled with molten copper, uniform bonded of the copper in the steel surface, and by molding. The combination is copper and steel metallurgy molecules.

2, excellent conductive properties:

Conductivity of the Continuous casting copper bonde steel grounding material more than 40%, when the transmission frequency is greater than 1.67MHz, its conductive properties fully comparable to solid copper.

3, corrosion resistance:

The horizontal continuous casting copper bonded steel grounding material surface is 99.9% copper, the copper layer and the binding layer is a combination of steel molecules overcome their electrochemical corrosion, and experiments show - copper loss was 0.017mm/Year. By calculating that copper clad steel grounding material, there is a strong resistance to corrosion buried in the soil, life of more than 40 years.

4, the combination of steel and copper layer uniformity:

Use exothermic welding joint continuous casting grounding materials to build connections grounding device, we can be seen as a reliable, stable and maintenance-free copper ground network.

Regardless of their service life, conductivity, potential difference within the network, the process of construction and investment costs, it is better than the traditional hot-dip galvanized steel construction.

**The main technical parameters of ground rod

1, the average thickness of the copper layer is ≥ 1.0mm

2, tensile strength ≥ 600N/mm2

3, Straightness error ≤ 1mmm

4, the copper layer plasticity: grounding rod (wire) bent 90 degrees, both inside and outside edge of the knuckle no cracks phenomenon.

5, the copper layer bond strength: After adhesion test, after Pointing Machine rolling, deformation combined with a good part of the copper steel, cracking and peeling does not appear.

**The main technical parameters of ground wire

1, the average thickness of the copper layer is ≥ 0.8mm

2, tensile strength ≥ 300N/mm2

3, Straightness error ≤ 1mmm

4, the copper layer plasticity: grounding rod (wire) bent 90 degrees, both inside and outside edge of the knuckle no cracks phenomenon.
