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).
