### **Copper Bonded Rods**

Copper bonded rods are an essential component in grounding and lightning protection systems. They are designed to ensure safety by providing a low-resistance path to dissipate electrical currents into the earth, protecting people, equipment, and structures from electrical surges, faults, and lightning strikes.

### **Key Features:**
1. **High Corrosion Resistance**
Copper bonded rods have a steel core coated with a layer of electrolytic copper. This copper layer provides excellent corrosion resistance, ensuring a long service life even in harsh soil and environmental conditions.

2. **Uniform Copper Bonding**
The rods are manufactured using molecular bonding, which results in a uniform and durable copper coating that adheres tightly to the steel core.

3. **High Conductivity**
The combination of a copper exterior and a steel core provides superior electrical conductivity, ensuring effective and consistent earthing performance.

4. **Durability**
These rods are designed to withstand mechanical stress and environmental degradation over time, making them suitable for long-term grounding solutions.

### **Specifications:**
1. **Material**: High tensile low-carbon steel core with a pure copper coating (99.9% purity).
2. **Copper Thickness**: Typically between 0.25 mm and 0.5 mm, as per standards like UL 467 and IEC 62561.
3. **Lengths**: Available in various lengths, commonly 1.2m, 1.5m, 2.4m, and 3m.
4. **Diameter**: Common diameters include 14.2 mm, 17.2 mm, and 25 mm.
5. **Threading**: Threaded at one end to facilitate easy coupling with another rod.

### **Advantages:**
1. **Cost-Effective**
Compared to solid copper rods, copper bonded rods offer similar performance at a lower cost, making them ideal for large-scale projects.

2. **Easy Installation**
They can be driven into the ground easily, and coupling options allow for deeper installations when required.

3. **Compliance**
Copper bonded rods meet various international standards for earthing, including UL, IEC, and IS standards.

### **Applications:**
1. **Lightning Protection Systems**
Used to create an effective grounding network for buildings and structures to protect against lightning strikes.

2. **Electrical Earthing Systems**
Essential for grounding in substations, transformers, communication towers, and industrial plants.

3. **Telecommunication Networks**
Protect sensitive telecom equipment from electrical surges.
