Armoured cables for signalling and interlocking
systems with copper conductors in PE insulation with protective
hose of PVC compound (ÒÓ Ó 31.3-00214534-008-2001)
Application:
These cables are intended for electric installations of railway
signalling systems, centralizing, interlocking and automation
systems of AC 380 V,50 Hz or AD 700 V.
They are employed in spaces where mechanical stresses on the
cable, including slight stretching forces, are possible.
The ÑÁÇÏÁáØï cables are laid in soil as their
cores have the water-repellent filling protecting the cables
from the longitudinal moisture spreading.
The ÑÁÏÁáØï cables have the similar design,
but they are without the water-repellent filling.
The ÑÁÇÏÁáØâ cables are laid in channels, in
tunnels,collectors and in soil as their cores have the water-repellent
filling protecting the cables from the longitudinal moisture
spreading.
The ÑÁÂÁáØâíã cables having the similar design
but without the water-repellent filling, are specially intended
for laying in looms in premises with risk of fire, in channels
and in tunnels.
Technical performance:
AC test voltage is 2500 V.
Maximum resistance of core at t =20°C:
for conductors with diameter of 0,9 mm is 28,8 Ohm/km;
for conductors with diameter of 1,0 mm is 23,3 Ohm/km.
Minimum electric resistance of insulation:
for cables without the water-repellent filling is 5000 MOhm
• km;
for cables with the water-repellent filling is 4000 MOhm •
km.
Maximum permissible bending radius shall be minimum 12 D, where
D is for the outer diameter of the cable.
The ÑÁÂÁáØâíã cables meet the requirements
of IEC 60332-3 A class in respect of localization of combustion
in looms.
