AMV-C-800SA10/30

Application

Nexans 800SA – the compact surge arrester that protects and enhances your medium voltage networks.

The Nexans EUROMOLD 800SA Interface C surge arrester is specifically designed to protect XLPE/EPR cables and medium voltage equipment against transient overvoltages (lightning, switching operations, and temporary overvoltages).

Installed directly within your Interface C cable terminations and coupling connectors, it helps improve network availability and reduce the risk of damage to sensitive equipment.

High‑performance protection technology

The 800SA is a metal‑oxide varistor (MOV) surge arrester, delivering effective and repeatable protection against overvoltages:

• Metal‑oxide varistor (MOV) technology with fast response, tailored to medium voltage networks.
• Energy rating: 2.5 kJ/kV, providing strong endurance against severe overvoltage events.
• Leakage/discharge current: 10 kA, ensuring reliable energy dissipation during surge peaks.

This technology ensures efficient voltage limitation at the cable and equipment terminals while maintaining a high level of long‑term reliability.

Compact design and system compatibility

Thanks to its compact Interface C design, the 800SA fits easily into substations, even where space is limited:

• Compact profile, ideal for confined substations and highly equipped switchgear rooms.
• 100 % EPDM body, robust and resistant to harsh environments.
• Touch‑proof design, fully aligned with operational safety requirements.

The 800SA is fully compatible with the Nexans EUROMOLD connector and coupler range:

• Compact T connectors 480TB, 484TB, 489TB (Interface C).
• Coupling connectors 800PB and 804PB.
• Nexans extenders from the same Interface C family.

This compatibility allows you to build coherent network architectures with dedicated surge protection on feeders, branches, couplings and three‑core cable distribution.

Typical applications in medium voltage networks

The 800SA surge arrester is ideally suited to:

• Protect cable terminations at transformers and medium voltage switchgear.
• Secure coupled links using 800PB/804PB and 480TB/484TB/489TB connectors.
• Reduce stress on conductors and cable screens during overvoltage events.

As a result, it helps extend the service life of cables and equipment and reduce unplanned outages caused by overvoltage incidents.

Key benefits

Choosing Nexans 800SA means:

• Enhancing protection of your medium voltage networks against transient overvoltages.
• Benefiting from a compact Interface C solution, easy to integrate into existing installations.
• Ensuring perfect compatibility with 480TB, 484TB, 489TB connectors and 800PB, 804PB couplers.
• Relying on Nexans quality and reliability, based on high‑grade materials (EPDM) and rigorous testing.

Nexans 800SA – the compact reference surge arrester for better‑protected, more reliable and more available medium voltage networks.
