Product catalog summary

Overview: This document details the specifications and characteristics of railway balise cables designed for the European Rail Traffic Management System (ERTMS). These cables feature a Low Smoke Zero Halogen (LSZH) fire retardant sheath and are engineered for durability and safety in railway signaling applications.

Standards: The cables are constructed according to proprietary designs for ERTMS balises and comply with standards such as EN 50266-2-4 cat. C, EN 50268-2-2, EN 50268-2, and NF C-20454.

Description and Application: The cables are armoured with one or two pairs for connecting the balise signaling system. They feature solid colored polyethylene insulation, an ATI sheath, and are armoured with two galvanized steel tapes. The outer sheath is made of green LSZH material, providing protection against external inductions, rodents, and ensuring zero halogen emissions. These cables are suitable for installation in ducts or direct burial in tunnels.

Construction Details:

Conductors: Annealed copper with a nominal diameter of 1.4 mm.
Insulation: High-density solid polyethylene.
Cabling Elements: Pairs.
Core Wrapping: Dielectric tape applied longitudinally with overlap.
Protection Sheath: LSZH material for one pair cable.
Cable Screen: Copolymer coated aluminum tape bonded to the inner sheath.
Intermediate Sheath: LSZH material.
Armour: Two 0.3 mm thick galvanized steel tapes.
Outer Sheath: UV resistant LSZH material, green RAL 6018.
Sheath Marking: Manufacturer's name, year, length marks, and customer-specific marks.

Electrical Characteristics (at 20ºC):

Conductor resistance: 11.9 Ω/km.
Loop resistance unbalance: 2.5%.
Minimum insulation resistance: 10000 MΩxkm.
Mutual capacitance: 45 nF/km.
Pair to ground capacitance unbalance: 2625 pF/km.
Dielectric strength: 1000 Vdc (conductor-conductor), 3000 Vdc (conductor-shield).

Transmission Characteristics (at 20ºC):

Nominal attenuation: 0.85 dB/km at 8.8 KHz, 4.5 dB/km at 560 KHz.
Characteristic impedance: 140 ± 10% Ω at 8.8 KHz, 120 ± 10% Ω at 560 KHz.
Far-end crosstalk: Minimum 66 dB/km at 8.8 KHz, 45 dB/km at 560 KHz; Typical 105 dB/km at 8.8 KHz, 75 dB/km at 560 KHz.

Reduction Factor, Rk (50 Hz): The induced voltage ranges from 100 to 1000 V/km with corresponding Rk values from 0.63 to 0.95.

Mechanical Characteristics:

Temperature range: -25º C to +75º C.
Bending radius: 15 times the cable radius.

Dimensions and Weights:

Diameter: 1.4 mm.
Code EA2Y0P6A4000102N: 1 pair, 16.0 mm diameter, 340 kg/km, 3000 m drum type A4.
Code EA2Y0P6A4000202N: 2 pairs, 18.0 mm diameter, 500 kg/km, 3000 m drum type A6.
