ENSTO branch connector for aluminum conductors SL2.11, for 16–50 mm² cables

ENSTO branch connector SL2.11 is a connector for making permanent electrical branches and taps between aluminum conductors with cross-sections from 16 to 50 mm². It is intended for use in low- and medium-voltage installations where a corrosion-resistant and mechanically stable connection is required. The connector is suitable for overhead lines, underground cables, distribution cabinets and field repairs, providing a compact solution for branching aluminum conductors in a variety of network environments.

Advantages

The branch connector provides reliable electrical contact between aluminum conductors while resisting galvanic corrosion and maintaining mechanical strength under typical installation stresses. Its compact construction facilitates installation in confined spaces such as distribution cabinets and junction boxes. Designed for long-term performance in both outdoor and indoor conditions, the connector supports a range of conductor sizes without the need for multiple connector types, simplifying inventory and deployment.

Suitable for

• Making permanent branches on overhead aluminum conductors
• Tapping aluminum cables in underground networks
• Distribution cabinet connections and service repairs
• Field installations where corrosion-resistant aluminum connections are required

Key specifications

• Compatible conductor cross-section range: 16–50 mm² (aluminum conductors)
• Intended voltage level: low- and medium-voltage network applications
• Connection type: permanent branch/tap connector for aluminum conductors
• Environmental suitability: designed for outdoor and indoor use, including overhead and underground installations
• Mechanical properties: designed to provide stable mechanical fixation and maintain electrical contact under typical service conditions

How to use

Select conductors within the supported cross-section range and prepare conductor ends according to standard installation practice, ensuring clean, oxide-free contact surfaces. Position the branch connector over the conductors to be joined or tapped and tighten the fastening elements to the recommended torque values for aluminum conductors. After mechanical tightening, verify electrical continuity and ensure any required protective measures, such as insulating covers or sealing, are applied in accordance with site rules and safety standards.

Usage recommendations

Use suitable tools and follow local electrical codes when installing the connector. Inspect conductor surfaces for oxidation and remove oxides where necessary before making the connection. Confirm compatibility with the specific aluminum conductor type and apply any specified anti-oxidation treatment or sealant if required by practice or regulation.
