Abstract:

Copper Bonded Steel Ground Rods are an innovative grounding material that combines the high conductivity of copper with the high strength of steel, widely used to reduce grounding resistance and improve the safety of grounding systems. This article will provide a detailed introduction to the technical parameters, performance testing, and application advantages of Copper Bonded Steel Ground Rods.

Ensuring the safe operation of electrical systems involves numerous measures, among which the design of the grounding system is crucial. Copper Bonded Steel Ground Rods, as an innovative grounding material, have gained widespread market recognition for their outstanding performance.

Ⅰ. Overview of Copper Bonded Steel Ground Rods

Copper Bonded Steel Ground Rods are a one-piece copper-steel composite material, with an outer layer of copper with a purity of 99.9% and an inner core of high-quality carbon structural steel. This composite metal material has a high bonding force and is mainly used for vertical grounding electrodes in grounding systems to reduce grounding resistance and improve the safety of the grounding system.

Ⅱ. Technical Parameters

The technical parameters of Copper Bonded Steel Ground Rods are as follows:
Tensile Strength: 350-770Mpa for vertical grounding; 290-510MPa for horizontal grounding.
Copper Thickness: 0.254mm to 0.8mm, customizable.
Ductility of Copper Layer: The product has no cracks in the inner and outer edge copper layer after being bent at 90° three times continuously.
Bondability of Copper Layer: Under specific conditions, the separation of the copper layer from the steel core is only allowed at the jaws of the vise, while the remaining part of the rod, the separated copper and steel, should not be visible to the naked eye.
Electrochemical Corrosion Performance: After the electrochemical corrosion cycle test, the final resistance value increase does not exceed 50% of the initial resistance value. Moreover, the resistance increase rate of each test step does not exceed 15% during the testing process, and the surface of the copper bonded steel sample is complete, without cracks, pits, or bubbling defects after the test.

Ⅲ. Product Advantages

1. High Conductivity: The high purity of the copper layer ensures excellent electrical conductivity of the ground rod.
2. High Strength: The internal carbon structural steel provides the necessary mechanical strength.
3. Corrosion Resistance: The copper layer effectively resists corrosion, extending the service life of the ground rod.
4. Customization Service: Customizable copper layer thickness and other parameters according to customer needs.

Ⅳ. Lead Time and After-Sales Service

Lead Time: Within 15 working days.
After-Sales Service: In case of product quality issues, our sales personnel and product engineers will respond within 24 hours.
