Insulation-piercing connector ENSTO SLIP22.1 for Al 10–95 mm² or Cu 1.5–70 mm²

ENSTO SLIP22.1 is an insulation-piercing connector engineered for establishing secure electrical connections without the need to strip conductor insulation. It is suitable for connecting aluminum conductors with cross-sections from 10 to 95 mm² and copper conductors from 1.5 to 70 mm². The design ensures stable mechanical retention and low-resistance electrical contact through insulation-piercing teeth, making it appropriate for distribution networks and service taps in both overhead and underground installations.

Advantages

The connector provides a rapid, repeatable method for making taps and branches while maintaining reliable conductivity. Its insulation-piercing mechanism eliminates the time and variability associated with stripping insulation and reduces the risk of conductor damage. Constructed for durable performance in typical utility environments, the product supports both aluminum and copper conductors across a wide range of cross-sections, enabling versatile deployment in distribution and service applications.

Suitable for

• Tapping or branching in low- and medium-voltage distribution networks
• Service connections for overhead lines
• Underground network branching and splices
• Applications requiring quick installation without insulation stripping

Key specifications

• Insulation-piercing type for through-insulation connections
• Compatible conductor materials: aluminum and copper
• Aluminum conductor range: 10–95 mm²
• Copper conductor range: 1.5–70 mm²
• Designed for use in overhead and underground power networks
• Provides mechanical retention and low electrical contact resistance

How to use

Select the appropriate connector orientation for the conductors to be joined and position the connector over the insulated conductors. Tighten the connector according to the manufacturer's recommended torque so that the insulation-piercing teeth penetrate the insulation and compress the conductors to create a conductive interface. Verify mechanical stability and electrical continuity after installation. Follow all applicable safety procedures and local regulations when working on live or de-energized circuits.

Usage recommendations

Use the connector with conductors within the specified cross-section ranges and preferred materials. Ensure correct tightening torque to achieve full penetration of the insulation and reliable contact. Inspect connections periodically as part of routine maintenance, and avoid using the connector on conductors with damaged insulation or corrosion that could compromise contact quality.
