FAQ

Questions engineers ask first

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

What is the difference between EN 50264-2-1 ('standard wall') and EN 50264-3-1 ('reduced wall')?
EN 50264-2-1 is the standard-wall elastomeric insulation series (0.8 to 3.2 mm wall depending on voltage and cross-section), providing heavy mechanical protection and both 0.6/1 kV and 1.8/3 kV ratings. EN 50264-3-1 is a reduced-wall series engineered to save space and weight in dense 0.6/1 kV control cubicles.
What do the insulation compound codes EI 101, EI 102, EI 103 and EI 104 mean in EN 50264-1?
Defined in EN 50264-1, 'EI' stands for Elastomeric Insulation: EI 101 is general-purpose (-25 °C), EI 102 is extra-low-temperature (-40 °C), EI 103 is oil- and fuel-resistant (-25 °C), and EI 104 combines both oil/fuel resistance and -40 °C low-temperature flexibility.
Why are 1.8/3 kV EN 50264-2-1 cables frequently used even in 400 V AC or 750 V DC railway circuits?
Similarly to industrial NSGAFÖU 1.8/3 kV cables, the thick 2.2–2.8 mm cross-linked elastomeric wall on 1.8/3 kV EN 50264-2-1 is considered inherently short-circuit and earth-fault-proof inside metallic traction cubicles and battery compartments.
Does EN 50264-2-1 satisfy EN 45545-2 Hazard Level 3 (HL3) for underground metro trains?
Yes. The electron-beam cross-linked halogen-free elastomeric compound achieves Hazard Level HL3 (the most stringent category, covering sleeping cars and underground metro/tunnel operation) under both R15 (interior) and R16 (exterior) requirement sets of EN 45545-2.
