## Summary description

ENSTO SLIW54 is an insulation-piercing connector designed for creating reliable electrical connections on insulated conductors with cross-sections from 16 to 120 mm². The connector pierces insulation to establish contact without pre-stripping, enabling fast installation in power distribution, branch tapping, and service connections. Suitable for outdoor and industrial use where secure, maintenance-free joints are required.

## Long description

ENSTO SLIW54 is an insulation-piercing connector designed to create secure electrical connections on insulated conductors with cross-sections from 16 to 120 mm². The connector establishes contact by piercing the conductor insulation, which eliminates the need for pre-stripping and enables faster installation. Built for outdoor and industrial power distribution tasks, the ENSTO SLIW54 is intended for branch tapping, service connections and situations that require maintenance-free joints and reliable conductivity.
Advantages
The ENSTO SLIW54 provides a fast, repeatable method for connecting insulated conductors without stripping, reducing installation time and potential human error. Its insulation-piercing design ensures a consistent electrical contact while protecting the conductor insulation from unnecessary handling. The connector is suitable for use in exposed environments and is made to offer durable performance and low maintenance over time.
Suitable for
 Branch tapping from main distribution lines.
 Service connections to buildings and industrial equipment.
 Outdoor power distribution and temporary or permanent joints.
 Installations requiring quick, reliable connections on insulated conductors (16–120 mm²).
When it may not be suitable
The SLIW54 is intended for insulated conductors within the specified cross-section range; it is not suitable for conductors smaller than 16 mm² or larger than 120 mm². It also may not be appropriate where regulations or installation practices require exposed conductor preparation or soldered/crimped joints. Applications demanding specialized sealing against aggressive chemical exposure or unique mechanical load ratings should be verified against applicable standards before use.
Key specifications
 Conductor cross-section compatibility: 16–120 mm².
 Connection type: insulation‑piercing connector (no pre-stripping required).
 Intended use: branch taps, service and power distribution connections.
 Environmental suitability: outdoor and industrial use, designed for durable, low‑maintenance joints.
 Electrical performance: designed to provide consistent conductive contact through insulation piercing.
How to use
Position the ENSTO SLIW54 over the insulated conductors to be joined, ensuring the conductor gauge falls within the 16–120 mm² range. Align the connector so the piercing element contacts the insulation at the intended tap point, then apply the recommended installation torque or mechanical compression method as specified by ENSTO instructions until the connector fully engages and pierces the insulation to form the electrical contact. Verify mechanical tightness and, where applicable, apply any specified environmental sealing or protective covers after installation. Follow local electrical codes and manufacturer installation guidelines for safe and compliant connections.
What to consider before purchase
 Confirm conductor cross-section falls within 16–120 mm².
 Check compatibility with the conductor insulation type and the installation environment (outdoor/indoor, exposure conditions).
 Review local regulations to ensure insulation‑piercing connectors are acceptable for the intended application.
 Ensure you have the correct installation tools and torque specifications required by the manufacturer.
Usage recommendations
Always follow ENSTO installation instructions and local electrical codes. Inspect connections after installation and periodically during service life to confirm continued mechanical integrity. Use the connector only within the specified conductor range and environmental conditions to ensure reliable, maintenance‑free performance.
