Introduction: The Unsung Hero of Passive Fire Safety
In the design of large-scale buildings, shopping malls, hospitals, subways, and tunnels, passive fire safety is the paramount priority. During the crucial time between the start of a fire and the completion of evacuation, the uninterrupted operation of critical electrical systems plays a vital role in ensuring life safety and property protection. This is where fire-resistant cables like the NHXCH FE180/E30 come into play.
In this in-depth article, we will analyze the technical features, safety advantages, and why the Erse Ervital NHXCH FE180/E30 cables, supplied by Delta Tema Elektrik, are indispensable for modern structures. These cables not only prevent the spread of fire but also guarantee the functional continuity of essential systems.
The Identity of the NHXCH FE180/E30 Cable: Technical Specifications
The NHXCH coding clearly explains the cable’s structure and performance characteristics:
- N: Indicates the standard (Generally VDE standard).
- H: Contains a Halogen-Free sheathing and insulation material. This prevents the release of toxic and corrosive gases during a fire.
- XC: Special, fire-resistant cross-linked polymer compound insulation.
- H: Indicates that the outer sheath is also halogen-free.
FE180 and E30: Function and Circuit Integrity
The fundamental feature that distinguishes these cables from standard flame-retardant cables are the two critical standards at the end of their name:
- FE180 (Fire Endurance – Resistance to Fire): Tested according to the IEC 60331 standard. This means the cable maintains its circuit integrity, continuing electrical transmission for at least 180 minutes (3 hours), even when directly exposed to the flame.
- E30 (Functional Integrity – System Integrity): Tested according to the DIN 4102-12 standard. This indicates that the entire system (including the installation), consisting of the cable, cable trays, and connection elements, maintains its function for at least 30 minutes during the fire. This is vital for the continuous operation of emergency lighting or the fire alarm system.
While higher levels like E60 or E90 (60 and 90 minutes of functional integrity) are also available, even E30 provides a significant layer of security for the critical evacuation process.
Why Halogen-Free Cables are Crucial for Safety
Traditional PVC cables emit dense, black, and toxic smoke when burned. This smoke obscures visibility in evacuation routes, leading to panic and respiratory poisoning. Halogen-free (LSZH) cables, such as the NHXCH FE180/E30, when combusting, offer:
- Low Smoke Density: Maintains visibility, facilitating evacuation (IEC 61034).
- Zero Toxic Gas Emission: Prevents respiratory poisoning (IEC 60754).
- Zero Corrosive Gas: Prevents the formation of acidic gases that damage sensitive electronic devices and metal surfaces even after the fire is extinguished.
These characteristics are a first priority in terms of evacuation safety, especially in areas with high human traffic.
Areas of Application: A Must-Have for Safety
The use of NHXCH FE180/E30 cables has become a legal requirement for critical systems that must remain operational even during a fire, including:
- Fire Alarm and Detection Systems: Sensors and panels that provide the initial warning.
- Emergency Lighting Systems: Lamps that illuminate escape routes.
- Smoke and Heat Extraction Fans: Ventilation systems that remove toxic smoke from the building.
- Fire Water Pumps: Control of pumps that supply water to firefighting systems.
- Emergency Lifts: Power supply for elevators reserved for rescue teams and the disabled.
- Public Address and Voice Alarm Systems: Uninterrupted transmission of evacuation announcements that direct people.
To ensure E30 functional integrity, it is crucial that special fire-resistant cable trays and clips are used during the installation of these cables.

Sustainable Safety and Long-Term Performance
The performance of these cables under high temperature and flame is crucial for the long-term safety of the facility. The NHXCH FE180/E30 sustains signal transmission even under arduous conditions, mitigating not only loss of life but also supporting business continuity after the fire. Many insurance companies and international standards organizations mandate the use of such cables in high-risk buildings. This demonstrates that the Return on Investment (ROI) comes not only from cost but also from risk reduction.
The Importance of Installation and Application
The installation and application processes are just as vital as the cables themselves for the continuity of the E30/E90 certification. Cable trays, supports, and junction boxes must also have the same fire resistance rating and be installed correctly. Incorrect installation can cause even the highest quality cable to prematurely lose its function during a fire. Therefore, in supplier selection, working with established firms like Delta Tema Elektrik, which offer technical support and application experience, directly impacts project success.

Conclusion: Your Investment Makes a Life-Saving Difference
Although NHXCH FE180/E30 cables represent a small expenditure in a building’s cost breakdown, their functional continuity and evacuation safety during a fire are invaluable. Investing in these fire-resistant systems is not only about meeting legal requirements but also about securing the lives of every individual within that building. To establish a long-lasting and safe infrastructure in your projects, choosing these cables with the assurance of Delta Tema Elektrik is a smart and responsible engineering decision.
