Why Choose the Cembre 2489090 DSV800 Copper Butt Connector?
The Cembre 2489090, manufacturer part number DSV800, is a heavy-duty tin-plated copper butt connector designed for joining large copper conductors in demanding electrical power installations. Manufactured from high-purity electrolytic copper, it provides a secure, low-resistance connection when installed using suitable Cembre crimping equipment and correctly matched dies.
Designed for conductors with a nominal cross-sectional area of 800 mm², the DSV800 enables two cable ends to be joined in-line while maintaining dependable electrical continuity and mechanical strength. Its tubular construction supports controlled conductor insertion and uniform compression during crimping.
The connector features a tin-plated surface that helps protect the copper body against oxidation and corrosion. Suitable for operating temperatures from approximately -50 °C to +150 °C, the Cembre DSV800 is well suited to power distribution, industrial infrastructure, utilities and other high-current cable connection applications.

Reliable Connections for High-Current Copper Cables
Copper butt connectors are used to create permanent in-line joints between conductors of the same compatible size. The stripped cable ends are inserted into opposite sides of the connector before the barrel is compressed using an approved hydraulic crimping tool and the correct die set.
When correctly installed, the Cembre DSV800 provides a mechanically secure and electrically efficient connection. Its high-purity copper body supports effective current transfer, while the tin-plated finish helps maintain long-term performance in industrial and utility environments.
Typical Applications
- High-voltage and low-voltage power cable installations.
- Electrical substations and utility distribution networks.
- Industrial switchgear and power distribution equipment.
- Renewable energy and power-generation systems.
- Heavy manufacturing and process plants.
- Infrastructure and large-scale electrical engineering projects.
