Roof Conductor Holder Clamp ARK Make | Lightning Protection Accessories by DFMHUB India
Why Roof Conductor Holder Clamps Matter in Lightning Protection
A Roof Conductor Holder Clamp is a critical mechanical and electrical interface in any lightning protection system (LPS). While air terminals and down conductors receive most design attention, failure at the conductor fixing point is one of the most common causes of lightning system malfunction in Indian installations.
The Roof Conductor Holder Clamp – ARK Make by DFMHUB is engineered to securely hold lightning conductors on rooftops while maintaining:
Correct conductor spacing
Mechanical stability under wind uplift
Long-term corrosion resistance
Electrical continuity as per IEC 62305
Designed and manufactured specifically for Indian climatic, structural, and regulatory conditions, ARK roof conductor holder clamps are used across industrial plants, commercial buildings, solar rooftops, data centers, oil & gas facilities, and infrastructure projects.
This page provides a technical, engineering-led, decision-maker-focused breakdown of the product — suitable for EPC contractors, consultants, MEP engineers, and safety auditors.
What Is a Roof Conductor Holder Clamp?
A Roof Conductor Holder Clamp is a mechanical fixing accessory used to:
Secure lightning protection conductors (copper, aluminum, GI)
Maintain defined separation from the roof surface
Prevent conductor displacement due to wind, thermal expansion, or vibration
It acts as the interface between the roof substrate and the lightning conductor network, ensuring that the designed lightning path remains intact throughout the system’s lifecycle.
Why ARK Make Roof Conductor Holder Clamp by DFMHUB Is Different
DFMHUB designs ARK lightning protection accessories with a manufacturer-first engineering approach, not as generic trading items.
Design Philosophy
Built for high-wind zones (coastal & cyclone-prone India)
Resistant to UV radiation, acid rain, industrial pollution
Compatible with flat RCC roofs, metal sheets, and solar mounting structures
Engineered for long service life with minimal maintenance

Design & Engineering Methodology
DFMHUB follows a step-by-step engineering methodology for ARK roof conductor holder clamps:
Step 1: Load Analysis
Wind uplift forces (as per Indian coastal zones)
Conductor self-weight and thermal expansion
Step 2: Material Selection
Base metal selected for mechanical strength
Coating thickness optimized for corrosion life cycle
Step 3: Electrical Continuity Validation
Contact resistance minimized
No arcing or sparking under impulse currents
Step 4: Environmental Durability
UV exposure testing
Moisture and salt spray resistance
Indian Conditions: Why Generic Imported Clamps Fail
Many imported clamps are designed for European conditions and fail prematurely in India due to:
| Indian Condition | Impact on Poor-Quality Clamps |
|---|---|
| High humidity | Rapid corrosion |
| Coastal salinity | Coating failure |
| Extreme heat | Material fatigue |
| Industrial pollution | Surface degradation |
| Monsoon winds | Mechanical loosening |
ARK Make clamps are engineered and tested with these Indian realities in mind.
