Modular traction substations

Modular traction substation produced by źAVL Reach Limited╗ is an integrated solution for reliable power supply of electric transport network. We also provide equipment setup, commissioning and lifetime support.

Modular traction substation designed to form either p0rtable or fixed electric power distribution point. 

Application of modern equipment and advanced solutions in the field of electrical engineering, based on years of experience, ensures safety and reliability in equipment operation.

Modular traction substation belongs to 17.5 kV voltage class and is designed for operation in automatic, maintenance-free mode. 

Modular traction substation is equipped with emergency lighting, heating, ventilation, air conditioning, security alarm and fire extinguishing systems. 




Main advantages:

  • minimum preparation works on installation site; 
  • high readiness for commissioning; 
  • ôplug-and-playö installation (simple connection of primary and secondary circuits);
  • possibility to easily configure different circuits
  • protection against unauthorised intrusion and/or disassembling
  • ease of equipment access; 
  • high level of operational safety. Well thought interlocking system guarantee high operational safety standard; 
  • utilisation of environmentally friendly materials;
  • compliance with international requirements and standards;
  • mobility with opportunity to be relocated by road and / or rail.
