MV and HV cables for Railways applications

Continued investment in the latest technology, materials and human resources enables Tratos to supply a wide spectrum of specialised railway cables. Fixed trackside power cables include High Voltage and Medium Voltage cables supplying power from the DNOs to NR substations and switchgear, including the single-core 25/44 kV OLE cable.

Cables range

Tratos MV cables are available with circular solid, compacted stranded aluminium conductors or compacted stranded copper conductors, all with triple extruded, dry-cured HEPR or XLPE insulation. Metallic insulation screens can be copper tape or wires, single or three core, armoured or unarmoured. Polyethylene, PVC or LSZH sheathed up to 26/45 kV in accordance with NR/PS/ELP/00008, BS 6622 and BS IEC 60840. Designs based upon BS 7835 and BS EN 60502 are also available on request

Tratos HV cables are available with circular stranded or segmental compacted copper conductors and triple extruded, dry-cured XLPE insulation. copper wires metallic insulation screen, single-core, unarmoured. Aluminium tape or lead sheath water barrier, HDPE sheathed. 

TRATOS® HV – 38/66 kV-(72.5 kV) and TRATOS® HV – 76/132 kV-(145 kV) – other voltages available on request

Designed to be maintenance-free, Tratos MV and HV cables offer exceptional long term reliability and performance.

BENEFITS

Tratos specialises in the Design, Development and Production of MV and HV cables up to 245 kV and has a great many years of experience supplying cables with proven reliability to Power Utility Companies worldwide. Tratos MV and HV cables are distinguished by the use of advanced technology to manufacture cables with increased pliability, decreased weight and increased strength. 

Tratos Engineers work closely with manufacturers of Medium (MV) and High Voltage (HV) accessory manufacturers including joints, terminations and fixings to help ensure a trouble-free installation.

APPLICATIONS

Tratos MV and HV cables are used to connect railway substations to the Distribution Network Operator (DNO) national power networks when the requirement is for underground not overhead cables, an increasing requirement to help protect areas of natural beauty or for localised biological and ecological reasons. 

Tratos also manufactures and supplies a range of innovative hybrid high-temperature low sag conductors when required.

INNOVATION – Tratos MV and HV cables are distinguished by Tratos’ ongoing investment in the latest technology, materials and human resources needed to meet the highest safety and performance requirements demanded by the Railway Industry. 

Tratos’ in-house testing facilities include one of the largest Faraday Cage buildings in Europe so we can control our production to follow and meet the requirements of national or international technical authorities and issue the appropriate type of test certification either with our approved in-house facilities or external laboratories.

  • Voltage Plugs 70 kV / 150 kV / 350 kV
  • Power 10.5 MW
  • Background Electrical Noise <0.1 pC.

Tratos Knowsley site in the Northwest of England also houses a large Faraday Test cage   

  • Voltage Plugs 50 kV / 75 kV / 100 kV
