## Summary description

ENSTO SEW20.72 is a single-sided shear-head crimp connector that pierces insulation for aluminium conductors with nominal cross-sections 35–157 mm² and bare conductor range 50–157 mm². Designed for mechanical and electrical connection of overhead or service lines, it enables reliable contact without full insulation removal. Suitable for field installation where quick, secure Al conductor joints are required.

## Long description

ENSTO SEW20.72 is a single-sided shear-head crimp connector for aluminium conductors. The connector is designed to pierce conductor insulation and form a mechanical and electrical joint for aluminium conductors with nominal cross-sections of 35–157 mm² and bare conductor range 50–157 mm². It is intended for use on overhead or service lines where a reliable electrical contact is required without the need to fully strip insulation, enabling faster field installation and secure Al conductor connections.
Advantages
The shear-head design provides a consistent crimp profile and controlled compression, reducing the risk of loose connections. Insulation-piercing capability eliminates extensive insulation stripping, saving time and reducing conductor handling. The connector supports a wide range of aluminium conductor sizes, making it versatile for various overhead and service line applications. Constructed to provide stable mechanical strength and electrical continuity, it is suited for field installations where durability and repeatable performance are required.
Suitable for
Mechanical and electrical connection of aluminium overhead conductors
Service line joints where insulation removal is limited or impractical
Field repairs and installations requiring quick, repeatable crimps
Applications using aluminium conductors 35–157 mm² (nominal) and bare 50–157 mm²
Key specifications
Connector type: single-sided shear-head crimp connector with insulation-piercing feature
Suitable nominal conductor cross-sections: 35–157 mm² (aluminium)
Bare conductor range: 50–157 mm²
Application: overhead and service line mechanical and electrical joints
Contact method: insulation-piercing to establish electrical contact without full insulation removal
How to use
Select the appropriate connector for the conductor size within the specified range. Position the connector on the insulated aluminium conductor so the insulation-piercing element aligns with the conductor. Apply the specified crimping force using a compatible shear-head crimping tool until the tool's shear action completes the crimp. Verify that the crimp head has sheared off as intended and check the mechanical tightness and electrical continuity of the joint. For bare conductors, position the conductor as required and crimp following the same procedure.
Usage recommendations
Use tools and dies recommended by the connector manufacturer to ensure the correct compression and shear action. Inspect conductors for damage before installation, and avoid repeated re-crimping on the same connector. Follow local electrical codes and safety practices when working on overhead or service lines.
