Power Systems has developed a new concept in unit substation design which brings together the unique benefits of oil/liquid filled padmount transformers as defined by the CSA specification C227.4, and SF6 switching technology using the Arc-Whipper© three position switch.

With all theses advantages:

• Compact size is only slightly larger than a padmount transformer. This unit can house up to 3 load break primary disconnects, fusing, secondary metering and distribution.
  
• Primary load break switches offer gas filled technology to provide maintenance-free service for the life of the unit.
  
• Interconnecting components of the switching to the transformer allow the switches to be unplugged from the transformer in minutes.
  
• All the primary compartments are submersible. There are no live parts, including the cable connections!
  
• Provision for grounding of any switch
  Available in an automatic transfer from 2 primary feeds.
  
• Available with Measurement Canada approved metering.
  
• Secondary can accommodate a wide range of breaker arrangements.
  
• Designed to meet the requirements of non-utility operated equipment.
  
• Completely tamperproof and weatherproof.
  
  Make Power Systems Technology the next choice of substations with the latest MiniSub.
