## Summary description

ENSTO SLIP12.05 is an insulation‑piercing connector designed to join aluminium conductors (10–50 mm²) with copper conductors (1.5–50 mm²) without removing insulation. The connector provides reliable electrical contact by piercing insulation and securing conductors mechanically, suitable for overhead lines, service taps, and distribution networks where mixed conductor materials are used.

## Long description

ENSTO SLIP12.05 is an insulation‑piercing connector engineered to join aluminium conductors (10–50 mm²) with copper conductors (1.5–50 mm²) without the need to strip insulation. The device secures conductors mechanically and establishes electrical contact by piercing the insulation with integrated teeth, enabling safe and fast connections for mixed‑material installations in overhead and distribution systems.
Advantages
The connector allows connection of aluminium to copper conductors while maintaining insulation integrity on the conductor cores, which reduces installation time and limits exposure to live parts. Its mechanical clamp design provides a consistent compression force and reliable contact pressure. Constructed from corrosion‑resistant materials suitable for outdoor service, the product supports repeated mechanical and electrical loads typical in service taps and distribution networks.
Suitable for
 Overhead line branch connections where aluminium and copper conductors meet
 Service taps from distribution conductors to building supply conductors
 Distribution network repairs and small extensions requiring mixed conductor material joins
 Field installations where insulation stripping is undesirable or impractical
When it may not be suitable
This insulation‑piercing connector is intended for conductors within the specified cross‑section ranges; it is not suitable for conductors outside these ranges or for connections requiring insulation removal for inspection or specific jointing methods. Applications that demand soldered, welded, or welded‑and‑heat‑shrunk joints for certification or where the connector’s mechanical design is incompatible with system mounting should use an alternative joining method.
Key specifications
 Aluminium conductor range: 10–50 mm²
 Copper conductor range: 1.5–50 mm²
 Insulation‑piercing contact mechanism with integrated teeth for direct connection through insulation
 Mechanical clamp for secure conductor retention
 Corrosion‑resistant materials suitable for outdoor installation
How to use
Position the aluminium and copper conductors in their respective channels of the connector without removing insulation. Align conductors as required by the connector body, then apply the specified torque to the fastening screw or clamp to compress the contact elements; this action pierces the insulation and establishes electrical contact. Verify mechanical retention and electrical continuity after installation, and follow local regulations for insulation sealing or additional protection if the connector will be exposed to aggressive environments.
What to consider before purchase
 Confirm conductor cross‑section sizes fall within the aluminium 10–50 mm² and copper 1.5–50 mm² ranges
 Check compatibility with the installation environment (outdoor exposure, temperature, UV) and any additional sealing requirements
 Ensure the connection method (insulation‑piercing) meets local electrical codes and utility specifications
 Verify required torque values and suitable tools for correct installation
Usage recommendations
Use recommended installation torque and perform a continuity test after tightening. Where long‑term outdoor exposure is expected, consider additional sealing or protective covers to limit moisture ingress and prolong service life.
