Railway & Metro Cables

UKB Electronics is a key supplier of specialized cables for India’s railway and metro infrastructure, engineered for the highest levels of safety and performance in demanding traction and signalling environments. Fully compliant with RDSO specifications and international rail standards, our cables support the nation’s transportation modernization as a premier “Make in India” partner.

Product Anatomy

Railway cables are built for extreme durability and safety. They feature highly flexible, fine-stranded copper conductors to withstand constant vibration. The defining characteristic is the use of advanced Electron-Beam (EB) cross-linked halogen-free polymers for insulation and sheathing. This high-tech material provides superior resistance to heat, oil, and abrasion, while offering excellent fire safety performance (low smoke, zero halogen).

Key Features and customization Options

Compliance: Designed and tested as per RDSO, EN, and IEC
Superior Fire Safety: Exceptional fire performance due to advanced EB cross-linked LSZH materials.
Extreme Durability: High resistance to constant vibration, mechanical stress, oils, and UV radiation.
High Flexibility: Engineered for easy installation in the confined spaces of rolling stock and trackside systems.
Applications: Used in locomotives, coaches, trackside signalling, station power, and communication systems.

Integrated Manufacturing Capabilities

Our technological superiority in rail cables stems from our advanced in-house processes:

Electron-Beam (EB) Cross-Linking: Our state-of-the-art E-Beam accelerator allows us to cross-link our polymer insulation in-house. This advanced process fundamentally enhances the material’s thermal, mechanical & chemical resistance, essential for high-performance rail cables.
Specialized LSZH Compounding: We formulate our own specialized halogen-free compounds, giving us precise control over their fire safety and durability characteristics.
Fine Wire Drawing & Stranding: Our in-house facility produces the highly flexible Class 5/6 conductors required to withstand the constant vibrations of a railway environment.
