Diagonal Clamp ARK Make by DFMHUB | Structural Lightning Protection Clamp for India
Lightning protection systems (LPS) are only as reliable as their mechanical and electrical continuity across structural members. The Diagonal Clamp ARK Make by DFMHUB is a precision-engineered component designed to ensure permanent, low-resistance bonding between diagonal, cross, and angular structural members in lightning protection and earthing systems.
Used extensively in steel structures, lattice towers, industrial sheds, substations, solar plants, and infrastructure projects, this diagonal clamp provides mechanically secure and electrically stable interconnection, even under India’s harsh environmental and electrical stress conditions.
Designed and manufactured in India, ARK diagonal clamps are optimized for high lightning current flow, corrosion resistance, and long service life, aligning with IEC 62305 lightning protection principles and Indian site realities.
What Is a Diagonal Clamp in a Lightning Protection System?
A diagonal clamp is a structural bonding component used to:
Electrically interconnect diagonal steel members, bracings, angles, or cross beams
Maintain equipotential bonding across metallic structures
Ensure continuous lightning current path from air termination to earth termination
Prevent dangerous side-flashing, arcing, or potential rise at structural joints
In structural lightning protection systems, especially where conductors cannot be routed linearly, diagonal clamps become critical to maintain electrical integrity.
Why Diagonal Clamps Are Critical in Indian Lightning Protection Projects
India experiences:
High lightning density zones (Odisha, West Bengal, Assam, Maharashtra, Kerala)
High soil resistivity variations
Extreme humidity, monsoon exposure, and coastal corrosion
Large steel-intensive infrastructure growth
Under these conditions, poor-quality clamps lead to:
Increased contact resistance
Corrosion-induced failures
Mechanical loosening under vibration
Non-compliance with IEC risk assessment outcomes
The ARK Make Diagonal Clamp by DFMHUB is engineered specifically to address these challenges.
