FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

Why specify BS EN 50382-2 instead of standard EN 50264 rolling-stock cable?
Standard EN 50264 cables use elastomeric compounds rated to +90 °C (or +110 °C). BS EN 50382-2 uses high-temperature silicone rubber rated for +120 °C or +150 °C continuous service, enabling higher current ampacity (reducing cable size and train weight) and safe routing near hot traction motors and braking resistors.
What is the difference between Class 5 and Class 6 conductors in EN 50382-2?
BS EN 50382-2 defines two conductor flexibility classes: Class 5 flexible tinned copper for fixed carbody and cabinet routing, and Class 6 extra-flexible tinned copper for dynamic carbody-to-bogie traction motor jumpers.
Does EN 50382-2 meet EN 45545-2 HL3 fire safety requirements?
Yes. The LSZH cross-linked silicone insulation (EI 111/112) and sheath (EM 107) meet EN 45545-2 Requirement Sets R15 (interior) and R16 (exterior) up to Hazard Level HL3.
What voltage and temperature ratings apply to EN 50382-2 under BS EN 50382-2?
EN 50382-2 is rated for 1.8/3 kV & 3.6/6 kV AC (maximum operating voltage 3.6 kV / 7.2 kV AC (5.4 kV / 9 kV DC), dielectric test voltage 6500 V AC (1.8/3 kV) / 11000 V AC (3.6/6 kV)) and continuous operation from -50 °C to +150 °C (short-circuit up to +300 °C) per BS EN 50382-2.
