Company “AVL Reach Limited” offers an outstanding solution in the field of energy distribution. 

We supply switchgears and provide lifetime equipment support enabling reliable power supply and trouble-free control. A skilful selection of components with high switching capacity, high dynamic strength to short-circuit currents and large mechanical resource is a distinguishing feature of AVL Reach switchgears that provides high reliability of equipment. 

Sophisticated electromechanical interlocking and protection system guarantees extraordinary safety level for maintenance staff.  

Main advantages:
  • Compact design; 
  • Utilisation of maintenance-free components;
  • High reliability; 
  • High level of safety for maintenance staff due to electromechanical interlock and protection; 
  • Provision of inspection convenience because of application of carriage-type element with circuit-breaker and disconnector; 
  • Built-in microprocessor traction network monitoring and protection system; 
  • Complete automation, exclusion of the human factor from substation equipment operation; 
  • High rated lifetime (30 years);
  • Environmental compatibility.
