10mm Copper Bonded Conductor for Structural Lightning Protection | ARK Make by DFMHUB India.
A 10mm copper bonded conductor is a critical current-carrying component used in structural lightning protection systems (LPS). It safely conducts lightning current from the air termination network through down conductors into the earthing system, minimizing thermal, mechanical, and electrical damage to structures.
The 10mm Copper Bonded Conductor – ARK Make by DFMHUB is specifically engineered for Indian climatic, soil, and regulatory conditions, offering superior conductivity, long-term corrosion resistance, and compliance with IEC 62305 lightning protection standards.
This page provides a complete engineering, performance, and compliance-focused overview—written for consultants, EPC contractors, developers, and electrical engineers—with zero marketing fluff.
Why 10mm Copper Bonded Conductor Is Critical for Structural Lightning Protection
A 10mm copper bonded conductor is a steel or copper core conductor molecularly bonded with high-purity copper, designed to safely carry lightning impulse currents from strike points to earth without melting, cracking, or corroding.
Role in a Structural Lightning Protection System
Forms the primary down conductor path
Ensures low-impedance current dissipation
Prevents side flashing and thermal damage
Maintains electrical continuity during high-energy impulses
Why Copper Bonded Conductors Are Preferred in India
India presents unique challenges for lightning protection design:
| Indian Condition | Impact on Conductor Selection |
|---|---|
| High soil resistivity (rocky, dry zones) | Requires high-conductivity conductors |
| Coastal & industrial corrosion | Demands bonded copper over GI |
| Extreme heat cycles (45–50°C) | Needs thermal stability |
| High lightning density regions (East, Central India) | Requires impulse-tested conductors |
The ARK Make 10mm Copper Bonded Conductor is designed to withstand:
Monsoon moisture
Industrial pollution
Coastal salinity
Long-term underground exposure
