Bayka company standard BayEnergy 02.

The cables are in compliance with EU LVD (Low Voltage Directive 2014/35/EU) and RoHS Directive EU 2011/65/EU - RoHS 2.0 and Regulation No. 1907/2006 (REACH).

The design with improved behaviour in the event of fire is
halogen-free according to DIN EN 50267-2-2,
flame retardant according to DIN EN 60332-1-2.

BayEnergy® aluminium railway grounding cables are used as grounding connection resistant to short-circuit current, for potential equalisation between rails and conductive parts not under voltage (e.g. posts, brackets of train preheating equipment, acoustic barriers, handrails). The advanced and improved railway grounding cables are marked using two blue Bayka identification strips® on the outer sheath, and document Bayka quality "made in Germany".

BayEnergy® aluminium railway grounding cables are approved by Germany's Federal Railway Office (EBA) and released for use in the area of operation of Deutsche Bahn AG.

The imprint "Eigentum DB" (Property of DB) or "Eigentum Verkehrsbetriebe" (Property of the Transport Services) is used as property notice and as theft protection. BayEnergy® aluminium railway grounding cables can be easily differentiated from copper grounding cables keeping potential thieves away.

Further properties:

  • Resistant against impact, vibration and shock loads
  • UV-resistant
  • Torsion-free laying can be easily checked
  • Easy laying and installation, handling with standard tools

In the case of DB AG, the EBA-approved design versions (N)AYY-O 1x110 ALMG and (N)A(St)YY-O 1x100 and/or 110 ALMGST, with special cable lug with adjusted diameter and water-tight aluminium for the short-circuit range greater 25 kA, are released for direct connection to the rail foot.

The design with improved behaviour in the event of fire is provided for installations in tunnels.
