ÑÁÇÏÓ, ÑÁÏó
Cables for signalling and interlocking
systems, with copper conductors, polyethylene insulation, in
thickened polyethylene sheath (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.
The ÑÁÏÇó cables are laid in soil as their
core has a water-repellent filling protecting the cable of the
longitudinal moisture spreading.
The ÑÁÏó cables 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 cables without water-repellent filling - 5000 MOhm •
km;
for cables with water-repellent filling - 4000 MOhm •
km;
Min bending radius 7 D, where D is outer diameter.
