​Underground and Submersible Oil Type Transformers

Developed by an engineering team specifically dedicated to this transformer range so as to meet specific characteristics and requirements, these products have streamlined sizes, aiming at reducing the requirement of installation space.
Picture
​What is the function of an underground and/or submersible transformer?Underground and/or submersible transformers are used in underground power distribution systems in large cities, able to operate in highly aggressive environments with risks of flooding. 
They are adjust the distribution voltage coming from the utility companies to the levels typical of the consumers, especially the commercial and residential ones in large urban centers.
WEG Advantages
​Developed by an engineering team specifically dedicated to this transformer range so as to meet specific characteristics and requirements, these products have streamlined sizes, aiming at reducing the installation space.
The verticalization of the manufacturing processes (making the electrical insulating varnish, electric wires, corrugated panels, tanks, insulating kits, coatings, etc.) is a remarkable characteristic and advantage of WEG, allowing broad quality control of the different production phases, as well as flexibility in lead times.
A wide network of accredit Technical Assistants is present all over Brazil, ensuring fast, local technical service and support to WEG's customers. 
Characteristics 
  • Designed in compliance with NBR 9369, they are benchmark of reliability, quality and high performance;
  • Usual outputs of 300, 500, 750, 1000, 1500 e 2000 kVA, in voltage classes up to 24.2 kV;
  • Reduced size, suitable for installation in places with little space, such as underground galleries;
  • Manufactured with vegetable oil or another fluid suitable for such kind of application;

 
  • Tanks with welded lids so as to ensure full sealing; 
  • Special high and low voltage bushings to keep the necessary insulation, even under full immersion;
  • Tubular or elliptical radiators to withstand high pressures; 
 Application
  • Underground distribution lines in central areas of large cities.
