Cables for signalling and interlocking
systems, with copper conductors, polyethylene insulation
(ÒÓ Ó 31.3-00214534-008-2001)
Application:
These cables are intended for electrical railway signalling,interlocking
and automation systems at AC 380 V voltage, 50 Hz or AD 700
V voltage.
These cables have the protection of the external electromagnet
impacts in the AC networks.
The ÑÁÇÏÀØï cables are laid in soil as their
core has a water-repellent filling protecting the cable of the
longitudinal moisture spreading.
The ÑÁÇÏÀØ cables have the same design but
without the water-repellent filling.
The ÑÁÇÏÀÁïØï cables are laid in soil, in spaces
possible mechanical stresses on the cable; the cable core has
a water-repellent filling protecting the cable of the longitudinal
moisture spreading.
The ÑÁÏÀÁïØï have the same design but without
the water-repellent filling.
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:
for the cables without the water-repillant filling is 5000 MOhm
• km;
for the cables with the water-repillant filling is 4000 MOhm
• km;
Min bending radius 15 D, where D is for the outer diameter of
the cable.
