Voltage switchgear

powerDChigh-speed

Up-to-date technologies are applied in our advanced DC switchgears series to provide more convenient and cost-effective application, easy installation and maintenance. Compact and reliable switchgear ensures uninterruptible power supply of traction network as well as personnel safety. Main specific features: application of maintenance-free components, produced by the global manufacturers, with high switching capacity, high dynamic resistance to short-circuit currents and large mechanical resource; electromechanical interlockings and protections guarantee high safety level for maintenance staff; unilateral maintenance ensures significant reduction of traction substation area; easy access to the components when carrying out routine maintenance; dust and moisture resistance (protection level IP 43); switchgears passed type tests in IPH Institut test center (Berlin, Germany) and meet IEC 61992-6 and EN 50123-6 standard requirements; total automation, human factor is excluded from switchgear real time control processes; built-in microprocessor traction network protection and monitoring system SMTN-3 meets EN/IEC 60255-1 standard requirements. Key benefits: substation space saving and decrease of expenses on capital construction due to overall dimensions reduction; high reliability level; maintainability and personnel safety; time and cost reduction on technical maintenance during the whole lifetime period; long lifetime (30 years); built-in microprocessor-based traction network protection and monitoring system. Application area: metro, city electric transport and railways traction substations with rated voltage 600..3300 V DC;
