Description

Roof Conductor Holder for Lightning Protection Systems | EarthingMart

Roof Conductor Holder is a critical mechanical component used to securely fix down conductors on rooftops as part of a complete Lightning Protection System (LPS). Designed for Indian climatic extremes—intense monsoon winds, high UV exposure, coastal salinity, and thermal cycling—EarthingMart Roof Conductor Holders ensure long-term conductor alignment, electrical continuity, and structural safety across industrial, commercial, and utility-scale installations.

Engineered for compliance with Indian and international standards, these holders are widely deployed by EPC contractors, MEP consultants, earthing specialists, and infrastructure developers across solar plants, substations, factories, data centers, and high-rise buildings.

Product Overview & Working Principle

A Roof Conductor Holder mechanically anchors aluminium or copper down conductors to flat or sloped roofs without compromising waterproofing or conductor integrity.

How It Works

1. Base Fixation: The holder base is anchored using mechanical fasteners or adhesive systems suited to RCC, metal sheet, or tiled roofs.

2. Conductor Seating: The round or flat conductor rests in a precision-formed saddle.

3. Secure Clamping: A corrosion-resistant clamp or cover locks the conductor in position, maintaining consistent spacing and routing.

4. Electrical Continuity: Design ensures no sharp bends or abrasion, preserving conductor cross-section and lightning current flow.

This controlled routing is essential for safely dissipating lightning currents (up to 100 kA peak) into the earthing system without side-flashing or mechanical failure.

Applications & Real-World Use Cases

Solar Power Plants (Rooftop & Ground-Mounted)

Case: 50 MW Solar Plant, Rajasthan
Roof conductor holders used on inverter rooms and control buildings exposed to rocky, high-resistivity soil (120–180 Ω-m) conditions. Ensured stable down-conductor routing during dust storms and peak summer temperatures.

Industrial Manufacturing Units

Case: Automotive plant, Pune
Installed across large RCC rooftops to maintain conductor alignment during heavy monsoon rainfall and thermal cycling.

Commercial & IT Buildings

Case: Data center, Bengaluru
Non-corrosive holders selected to prevent EMI risk and maintain strict routing compliance for lightning down conductors.
