II. Technical Specifications

The Feichun AFUMEX N2XSH 1.8/3KV track feeder cable boasts a set of advanced specifications designed to ensure performance, safety, and longevity. Below are the key technical details:

III. Standards and Compliance

A. Importance of Standards Compliance

The Feichun AFUMEX N2XSH 1.8/3KV track feeder cable has been carefully engineered to meet several international standards.

Ensuring compliance with these regulations guarantees that the cable provides superior safety, performance, and reliability, particularly in fire-sensitive environments such as tunnels, industrial plants, and power stations.

B. Key Standards

• DIN VDE 0271: This standard sets guidelines for PVC-insulated cables, providing context for general cable construction.

• DIN VDE 0276-604: Pertains to power cables with extruded insulation, providing context for cables rated for higher voltages.

• DIN EN 50267-2-2: Outlines common test methods for cables under fire conditions, focusing on the gases evolved during combustion.

• DIN EN 60332-1-2: Defines flame propagation tests for single cables, ensuring fire safety.

• DIN EN 50575: Establishes fire performance standards for cables used in construction works.

IV. Common Challenges and Solutions in Trackside and Industrial Applications

A. Fire Safety in Tunnels and Confined Spaces

One of the most significant challenges in tunnels and industrial environments is ensuring fire safety. Conventional cables can emit toxic gases and thick smoke in the event of a fire, posing serious risks to human health and infrastructure.

The halogen-free and low-smoke properties of the Feichun AFUMEX N2XSH cable are designed to solve this problem by significantly reducing the harmful effects of fire. The B2ca CPR classification ensures that the cable meets high fire safety standards, reducing smoke production and flaming droplets, while also maintaining low acidity of evolved gases.

B. Electromagnetic Interference (EMI)

In environments where sensitive electronic equipment is present, electromagnetic interference (EMI) can be a significant concern.

The metal tape and wire screen in the Feichun AFUMEX N2XSH cable effectively shield against EMI, ensuring the cable does not disrupt or interfere with nearby equipment.

This is especially important in railway systems and industrial facilities that rely on electronic systems for operation and safety.

C. Installation in Ducts and Free Air

Installing cables in ducts or free air environments can present challenges related to physical protection, support, and exposure to the elements.

The Feichun AFUMEX N2XSH is designed to withstand these installation conditions, but care must be taken during installation to avoid damage. Proper cable support, spacing, and handling are critical to ensuring the cable performs optimally over time.

D. Environmental Exposure (UV Radiation, Moisture, Temperature Variations)

Cables exposed to UV radiation, moisture, and temperature fluctuations can suffer degradation over time, leading to potential failures.

The LSZH outer sheath of the Feichun AFUMEX N2XSH cable provides excellent protection against these environmental factors, ensuring the cable’s long-term reliability and reducing the need for frequent maintenance or replacement.

V. Installation and Maintenance Best Practices

To ensure the optimal performance and longevity of the Feichun AFUMEX N2XSH 1.8/3KV cable, it is important to follow proper installation and maintenance practices. Below are some best practices for installation and maintenance:

A. Proper Cable Handling

• Avoid kinking or creating sharp bends during handling and installation.

• Do not exceed the minimum bending radius specified for the cable to prevent mechanical stress and potential damage.

B. Installation in Ducts and Free Air

• Ensure proper support and spacing of the cable during installation to avoid mechanical damage.

• Use appropriate ducting systems when installing the cable in ducts or conduit to provide physical protection.

C. Correct Termination and Connections

• Always use appropriate connectors and termination accessories that are designed for XLPE cables and shielded cables. This helps to ensure a secure connection and prevent water ingress or electrical failures.

D. Regular Inspection

• Conduct regular visual inspections of the cable, especially in areas exposed to mechanical stress or harsh environmental conditions. Look for signs of abrasion, cracking, or moisture damage.
