Electric wire connector CellPack 374492, screw-type Al‑Cu connector, for conductors up to 36 kV, 1 pc

CellPack 374492 is a screw‑type electric wire connector engineered for reliable Al‑Cu conductor connections in medium‑voltage systems up to 36 kV. Supplied as a single piece, the connector is intended for mechanical and electrical joining of conductors in overhead lines and cable terminations. Its design supports repair, maintenance and new installations in power distribution networks where Al‑Cu transitions are required.

Advantages

The connector provides a compact screw‑type solution that secures aluminum-to-copper joints while maintaining electrical continuity suitable for medium‑voltage use. Its construction is focused on ensuring a stable mechanical clamp and consistent contact pressure across conductor surfaces. Supplied as an individual unit, the product is convenient for targeted repairs and phased installations where single connectors are needed.

Suitable for

• Aluminum-to-copper conductor joints in medium‑voltage networks (up to 36 kV)
• Overhead line terminations and splices
• Service, repair and maintenance work on distribution lines
• Cable termination points requiring a screw‑type mechanical connector

When it may not be suitable

This screw‑type connector is specified for Al‑Cu conductor connections in medium‑voltage applications; it may not be suitable for low‑voltage or high‑voltage systems beyond the 36 kV rating. The connector is a single piece intended for direct conductor joining and does not replace insulated joints, full enclosures, or specialized fittings required in certain environmental or safety‑critical installations.

Key specifications

• Connector type: screw‑type mechanical connector for Al‑Cu conductors
• Voltage rating: up to 36 kV (medium‑voltage applications)
• Conductor compatibility: aluminum to copper conductor transitions
• Packaging: single piece supplied
• Intended use: overhead lines and cable terminations for power distribution

How to use

Select conductors with compatible cross‑sections and prepare conductor ends by stripping insulation and cleaning contact surfaces to remove corrosion or contaminants. Position the aluminum and copper conductors in the connector according to the manufacturer's orientation guidance and tighten the screw clamp to the recommended torque to ensure secure mechanical and electrical contact. After installation, verify continuity and mechanical stability; for final installations, use any recommended counter holder or accessory fittings if specified for mounting or strain relief.

What to consider before purchase

• Confirm the connector's 36 kV voltage rating matches the application requirements
• Ensure conductor types and cross‑sections are compatible with a screw‑type Al‑Cu connector
• Check whether a counter holder or additional accessories are required for installation
• Assess environmental and insulation needs—connector is not an insulated joint by itself

Usage recommendations

Use appropriate torque tools and follow safety procedures for medium‑voltage work. Where recommended, install the CellPack counter holder or other compatible accessories to support mounting and strain relief. Perform electrical and mechanical tests after installation and include corrosion protection measures on exposed aluminum surfaces where applicable.
