Contact lines

Aim:

• basics of contact line construction and design

Content:

• requirements and specifications
• contact line systems - structure and design (overhead contact line systems, overhead conductor rail systems, conductor rail systems)
• dimensioning of contact lines based on overhead contact line systems
  • mechanical dimensioning (loads, elongation, sag, behaviour of fixed tensioned wires, wind deflection, span lengths and tensioning lengths, headspans, poles and foundations)
  • electric dimensioning (network simulation of running trains, thermal dimensioning, return circuit)
  • interaction between pantograph and overhead contact line (static and dynamic factors of the interaction, influence of the design parameters, simulation of the interaction with Sicat Dynamics)
• design phases of contact line systems (system, basic, allocation & construction design, design documents, computer-based engineering)
• design principles of overhead contact line systems (e.g. electric separations, protection and phase separation sections, catenary drops, turnouts)
• contact line components (materials, production processes, design, quality control and inspection)

Time:
