Electrical installations: understand the reaction and fire resistance of cables

This article outlines the two key fire-safety performances of electrical cables: reaction to fire, describing how a cable behaves when exposed to flames, and fire resistance, ensuring electrical continuity of safety systems under extreme temperatures.

It explains how fires develop, why smoke is the main hazard, and the role of LFH (Low Fire Hazard) cables in limiting fire growth. You will also learn how to identify high-performance cables using the Euroclasses defined by the Construction Products Regulation (CPR). The article further details fire-resistant cables, their applications (FAS, CMSI, emergency lighting…), their technical specificities, and their critical importance in buildings such as ERP and high-rise structures.

Historical Evolution of the Regulation on Construction Products (CPR)

From the Treaty of Rome to today’s Construction Products Regulation, Europe has progressively built a unified framework to ensure fire safety in buildings.
Discover how key milestones — from the 1988 CPD to the 2017 CPR application to cables — shaped the standards that protect lives and infrastructure across the EU.

How do electrical cables help prevent fires?

Electrical cables play a key role in fire prevention. Through their technical performance — limiting fire spread, reducing smoke emissions, and maintaining power to safety systems — they directly protect people and buildings. The new French regulation of May 2024 now requires Cca-s2,d2,a2 certified cables in public and high-rise buildings. With its Nexans FR-N1X6G3 PROTECT range, Nexans fully meets these requirements by combining safety, performance, and compliance with European standards.
