## Summary description

ENSTO SP16 SLW25.22 is an insulation‑piercing connector designed for aluminium conductors with cross-sections from 50 to 157 mm². It features an insulating cover and shear‑head screws that ensure consistent clamp tightening and reliable electrical contact without stripping conductor insulation. Used for branch tapping and line connections in overhead and distribution networks where secure, durable joints are required.

## Long description

ENSTO SP16 SLW25.22 is an insulation‑piercing connector designed for use with aluminium conductors in the 50–157 mm² cross‑section range. The connector allows branch tapping and line connections without removing conductor insulation, using a pierce‑type contact that forms a reliable electrical path. An insulating cover provides weather protection and electrical insulation, while shear‑head screws ensure consistent clamp compression and reduce the risk of under‑ or over‑tightening.
Advantages
The insulation‑piercing design permits quick installation without stripping conductor jackets, saving time and reducing error. Shear‑head screws deliver uniform torque and consistent contact pressure for improved long‑term conductivity. The integrated insulating cover protects the connection from moisture and contaminants and contributes to safer handling during installation and service. Constructed for aluminium conductors within the specified cross‑section range, the connector supports secure mechanical and electrical performance in overhead and distribution network applications.
Suitable for
 Branch taps on overhead aluminium conductors
 Line splices and service connections in distribution networks
 Temporary or permanent connections where insulation must remain intact
 Field installations requiring consistent torque and quick assembly
Key specifications
 Compatible conductor material: aluminium
 Conductor cross‑section range: 50–157 mm²
 Connection type: insulation‑piercing (no stripping required)
 Fastening: shear‑head screws for controlled tightening
 Protective feature: insulating cover providing environmental protection
How to use
Select a connector appropriate for the conductor cross‑section and confirm conductor material is aluminium. Position the connector over the live and branch conductors so the piercing elements align with the conductor insulation. Tighten the shear‑head screws using the recommended tool until the screw heads shear off, indicating correct torque and compression. After fastening, fit the insulating cover fully to protect the joint from moisture and contaminants. Follow applicable electrical safety procedures and local regulations during installation.
Usage recommendations
Use this connector only with aluminium conductors within the specified size range and verify mechanical and electrical integrity after installation. Avoid reusing connectors that show visible damage or deformation. Store and handle connectors in a dry environment to maintain insulating cover condition and ensure reliable long‑term performance.
