ATR switchgear and its applications

Progetto di economia circolare per acciaieria in Siria.

The medium-voltage switchgears are essential in the electrical network, from the energy delivery (HV-MV) up to its distribution. Air-insulated (AIS) medium-voltage switchgears, suggested for indoor installations, are used for several applications, such as:

  • Infrastructure (Hospitals, residential, industrial plants, data centers)
  • Solar plants
  • Wind plants
  • National distribution grid
  • Transports (Airports, Railway, Metro)
  • Seaports and ship
  • Oil & gas plants
  • Mines

ATR is air-insulated medium-voltage switchgear developed by C.R. Technology Systems and includes the following key strengths:

  • Flexibility
  • Modularity
  • Safety (for the personnel)
  • Easy to install
  • Reliabillity
  • Customization
  • Extendable with a high range of typical panels

Thanks to its strong technical features (36kV of rated voltage-2500A of busbar current-25kA of short-circuit current, degree of protection up to IP54), ATR is suitable for severe environmental conditions (>1000m of altitude, +55°C temperature, protection against corrosive gases) assuring a high level of continuity service.

The broad ATR range includes switch-disconnector units, switch-disconnector and fuses units, switch-disconnector and circuit-breaker units, metering units, cable riser units and busbar riser units.

Depending on every functional ATR unit, each one can be equipped with 3 position switch-disconnector, Vacuum or SF6 circuit-breaker, traditional current transformers, ring current transformers, voltage transformers, fuses, surge arrestors, protection relays, network analyzer, multimeter, tariff meter, lamps, push buttons, selector switches and all necessary to the proper work, and based to the project/request, a huge level of customization.
