Cembre 2489090 DSV800 tin-plated electrolytic copper butt connector designed for crimped in-line connections between compatible 800 mm² copper conductors.
£136.10
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.
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.

The Cembre 2489090 DSV800 is used to create a permanent in-line crimped joint between compatible 800 mm² copper conductors.
The connector is designed for copper conductors with a nominal cross-sectional area of 800 mm².
The DSV800 is manufactured from high-purity electrolytic copper and features a tin-plated surface for additional protection against oxidation and corrosion.
The stripped conductor ends are inserted into the connector and compressed using a suitably rated Cembre hydraulic crimping tool with the correct dies for the connector and conductor size.
No. The DSV800 is a non-insulated copper connector, so suitable insulation and environmental protection must be applied after crimping where required by the installation.
Cembre cable connectors are widely used by electrical engineers, utilities and industrial contractors to create reliable, mechanically strong and electrically efficient conductor connections in demanding power applications.
