Cables for signalling and interlocking
systems, with copper conductors, polyethylene insulation, in
polyvinylchloride (PVC) sheath (ÒÓ Ó 31.3-00214534-008-2001)
Application:
These cables are intended for electrical signalling installations
on railways, interlocking and automatics at AC 380 V voltage,
50 Hz or DC 700 V at -40°C up to 60°C.
Cables are laid in premises, channels, tunnels at aggressive
medium and with no mechanical impacts on the cable.
Technical performance:
AC test voltage is 2500 V.
Maximum resistance of core at t =20°C:
with diameter of 0,9 mm - 28,8 Ohm/km;
with diameter of 1,0 mm - 23,3 Ohm/km.
Min resistance of insulation 5000 MOhm • km.
Min bending radius 7 D, where D is for the outer diameter of
the cable.
The ÑÁÂÁÃíã cables meet the requirements of
IEC 60332-3 class A when lying in bunches.
The ÑÁÂÁÃíã cables meet the requirements of
IEC 60332-3 class A when single-laying.
