10mm Cross Connector Clamp ARK Make by DFMHUB for Structural Lightning Protection Systems
The 10mm Cross Connector Clamp ARK Make by DFMHUB is a precision-engineered bonding and interconnection component designed for structural lightning protection systems (LPS) as per IEC 62305.
Specifically developed for Indian infrastructure conditions—including high lightning density zones, aggressive soil chemistry, coastal humidity, industrial pollution, and extreme temperature variations—this clamp ensures permanent, low-resistance electrical continuity between crossing down conductors, rebars, or earth conductors of 10mm diameter.
Used extensively by consulting engineers, EPC contractors, infrastructure developers, and industrial facility owners, the ARK Make 10mm Cross Connector Clamp is a critical reliability component in modern lightning protection and equipotential bonding networks.
What Is a 10mm Cross Connector Clamp?
A cross connector clamp is a mechanical bonding device used to electrically and mechanically connect two conductors crossing at 90°. In lightning protection systems, this ensures:
Continuous current flow during lightning discharge
Equipotential bonding of structural elements
Prevention of side-flashing and dangerous potential differences
Why 10mm Size Matters
A 10mm conductor (solid or stranded) is commonly used in:
Structural lightning down conductors
Rebar-based natural LPS
Equipotential bonding networks
The clamp must maintain:
High clamping force
Corrosion resistance
Stable contact pressure over decades
Role of Cross Connector Clamps in Structural Lightning Protection
Step-by-Step Engineering Methodology (IEC 62305 Aligned)
Air Termination Captures Lightning Strike
Down Conductors Carry Impulse Current
Cross Connector Clamp Bonds Intersecting Conductors
Equipotential Distribution Across Structure
Safe Dissipation into Earth Electrode System
The cross connector clamp is critical at junction points, especially in:
RCC columns
Steel frames
Rebar grids
External down conductor crossings
