Bayka company standard TUSI,
based on DIN VDE 0816/part 1/2.88 and Dlk 1.013.151.

The cables are in compliance with EU LVD (Low Voltage Directive 2014/35/EU) and RoHS Directive EU 2002/65/EC - RoHS 2.0 and Regulation No. 1907/2006 (REACH).

For the design with improved behaviour in the event of fire:
no fire propagation acc. to IEC 332-3-24 (Category C),
smoke density acc. to IEC 1034-2, and
smoke gas corrosivity acc. to IEC 60754-2

Prescribed as data cable for OLSP systems (overhead contact line voltage test) in tunnels, for the connection of safety and signal equipment in tunnel areas for operating voltages ≤ 225 V (peak value).

It is suitable for low-loss transmission of alternating currents up into the high-frequency range, in systems requiring insensitivity towards one another, against external interference and against earth potential.

The cable is tested under increased tensile loads (WKT test for tensile strength) and offers a VDE registration no. and approval by Germany's Federal Railway Office (EBA).

The bending radius for repeated bending applies to the radius of switching mechanisms, too.
Tensile stress only valid when cable sheath and cable core involved.
