Signalling & Control Cable to French Rail Standard
According to French rail, intercity railway signalling cables rated 750V are meant for signal circuits which link permanent installations situated along rail tracks. They are generally installed in conduits and meet the ST 698G (ZPGU-ZPAU Series) and CT 362 (ZCO3 Series) standard. They are multicore or multipair signalling and control cables providing low voltage energy and two way telecommunications for field equipment. The key features lie in the electromagnetic immunity with high reduction factor, especially for high speed lines.
Unarmoured Local Link Cables (ZPGU Series)
The unarmoured ZPGU cables are used mainly on short distance links inside or outside the service cabins.
Armoured Main Signalling Cables for non electrified lines or 1500V DC Lines (ZPFU Series)
The armoured ZPFU cables are used for the main circuits of 1500V DC electrifi ed lines.
Armoured Main Signalling Cables for 25KV AC electrified lines (ZPAU Series)
These cables are called“ Anti Induction Cables” which are recommended for use in the main circuits of electrifi ed lines in 25KV A.C. They are designed with improved protection against induction according to the following principle: when a telecommunication line is affected by electrical and magnetic fi elds resulting from the power supply voltage of the catenaries (25KV A.C.), there is an electromotive force induced between conductors and earth. The anti induction cables include several layers of metallic screens (copper and steel) to provide a very effi cient protection against interferences.
Armoured Main Signalling Cables for High Speed Train lines (ZCO3 Series)
The basic application of ZCO3 cables is for the carrier current signal system of high speed train line (TGV). Due to an increase in the induction screen thickness and the steel armor, their anti induction protection is much higher than the ZPAU Series cables.
Equipment Cables for Control Centers (ZUG/SUG/ZUT, CV/CVZ & SCG Series)
ZUG/SUG/ZUT are equipment cables installed in traffi c control centre or trackside equipment shelter, used for indoor interconnection between the computer devices and railway network equipment. ZUG & ZUT are multipair equipment cables and SUG are multicore equipment cables. CV/CVZ cables are used as cabling wires for the relays and electronic equipment. The cables are suitable for use only in Optical Control Panel (OCP) wiring. The SCG cables are designed for connect the equipment centre to the device concerned. The cables are used as local control or power supply cables for trackside and between the rail equipments.
K23 Cables
K23 are main armored LSZH multiquad signalling cables for metro local train and tramlines. They are designed for remote controls and teletransmissions in underground railway networks. The cables are used for digicode cable signalling, being laid in channel, cable tray, or on hook supports, along suburban railway lines, electrifi ed at maximum 1500V DC. The cables have aluminium moisture barrier, double steel tape armour and LSZH sheath.
K24 Cables
K24 are LSZH multipair signalling cables for metro local train and tramlines. They are designed for remote controls and teletransmissions in underground railway networks. The cables are used for digicode cable signalling, being laid in channel, cable tray, or on hook supports, along suburban railway lines, electrifi ed at maximum 1500V DC u, b. K24 have aluminium moisture barrier and LSZH sheath, with optional double steel tape armouring,
Digicode Cable
Digicode Cable are indoor railway signalling cables designed for transmission of track circuit digicode signals up to 30KHz in electrifi ed lines, being installed in cable trays. The cables are covered by fl ame retardant LSZH sheath with double layers of steel tapes, with low capacitance values.
