## Long description

ENSTO SEW20.31 is a grounding clamp designed for secure earth connections on aluminum conductors with cross-sections from 35 to 157 mm². The clamp includes an angled fitting to ensure stable mechanical and electrical contact and is suitable for both permanent and temporary earthing in power distribution, overhead lines and substation applications. The design provides reliable conductor-to-ground connection where safe discharge paths and effective bonding are required.
Advantages
The grounding clamp is manufactured to provide consistent clamp pressure and corrosion-resistant contact between the aluminum conductor and the earthing connection. Its angled fitting facilitates installation in confined or offset positions and reduces the need for conductor repositioning. The product is compatible with a range of aluminum conductor sizes within the specified cross-section range and is intended for straightforward integration into existing earthing and bonding systems.
Suitable for
 Permanent earthing points in distribution networks
 Temporary grounding during maintenance and line works
 Overhead line and substation bonding
 Connections on aluminum conductors within the specified cross-section range
Key specifications
 Conductor material compatibility: aluminum
 Supported conductor cross-section range: 35–157 mm²
 Connection type: mechanical grounding clamp with angled fitting
 Application environments: power distribution networks, overhead lines, substations
 Usage: suitable for permanent and temporary earthing and bonding
How to use
Position the clamp on the aluminum conductor so that the contact surfaces align with the conductor outer surface. Tighten the clamp fasteners to the recommended torque for this product family to ensure secure mechanical and electrical contact; verify contact integrity visually and by measuring continuity or resistance as appropriate. Use the angled fitting to accommodate offset mounting positions; if necessary, adjust conductor positioning to achieve correct seating. For temporary earthing, attach the earthing lead to the clamp and confirm a low-resistance connection before starting work.
Usage recommendations
Inspect contact surfaces for corrosion or contamination prior to installation and clean as needed. Confirm that the selected clamp covers the conductor cross-section and that fasteners are tightened to specified values. For long-term installations, consider periodic inspection to ensure ongoing low-resistance contact and mechanical stability.
