## Summary description

Insulation-piercing connector ENSTO SLIW50 designed to create reliable electrical connections without removing conductor insulation. Supports main conductors 10–50 mm² and tap conductors 1.5–10 mm². Provides mechanical clamping and conductive piercing for overhead and distribution networks, branch tapping, and repairs where quick, sealed connections are required.

## Long description

The ENSTO insulation-piercing connector SLIW50 is designed to form secure electrical connections without stripping conductor insulation. It accepts main conductors with cross-sections from 10 to 50 mm² and tap conductors from 1.5 to 10 mm². The connector uses a combined mechanical clamping and insulation-piercing principle to ensure electrical contact while maintaining a sealed interface suitable for overhead and distribution networks, branch tapping, and rapid on-site repairs.
Advantages
The connector eliminates the need to remove insulation from conductors, reducing installation time and lowering the risk of conductor damage. Its insulation-piercing design provides reliable electrical contact and consistent performance under typical outdoor and indoor distribution conditions. The mechanical clamping secures conductors and maintains contact pressure, while the housing design helps protect the joint from environmental influence. Installation can be performed with standard tools, enabling fast and repeatable connections.
Suitable for
Branch tapping of overhead and low-voltage distribution lines
Repairs and temporary connections in distribution networks
Connecting service drops and secondary feeders
Situations requiring quick sealed electrical joints without insulation removal
Key specifications
Main conductor cross-section: 10–50 mm²
Tap conductor cross-section: 1.5–10 mm²
Insulation-piercing contact principle for both conductors
Mechanical clamping to secure conductors and maintain contact pressure
Suitable for overhead and distribution network applications
Designed for sealed joints against common environmental conditions
How to use
Position the main conductor and the tap conductor into their respective grooves in the connector according to conductor size. Apply the recommended torque with a compatible tool to compress the housing and drive the insulation-piercing teeth through the conductor insulation until the specified clamping force is reached. Verify that conductors are held firmly and that the connector is fully closed to form a sealed joint. Follow local electrical codes and standard safety procedures during installation, including de-energizing circuits when required.
Usage recommendations
Use the ENSTO SLIW50 connector on conductors within the specified cross-section ranges and follow manufacturer torque settings where available. For long-term outdoor installations, ensure connections are accessible for inspection and protected from mechanical strain. When performing live-line work, only trained personnel with appropriate tools and safety measures should proceed.
