• Designed according to the criteria established by NBR standard 5356 or complying with the specifications of the power utility company and/or specific requirements of each application;

• Usual outputs of 5/6.25, 7.5/9.375, 10/12.5, 15/18.75, 20/25, 25/31.25, 40/50 MVA, in general in voltage classes up to 230 kV, when three-phase (for single-phase banks, this output range may include even higher voltages);

• Voltage regulation made by on-load tap changer (OLTC) and No-Load Tap Changer (NLTC);

• High-performance equipment;

• Step-lap-type magnetic core, resulting in optimization of the noise level and low exciting current, in addition to better natural anchoring of the set to withstand short circuit stresses;

• Conductors covered with thermostabilized insulating paper class E (120 °C), whose special characteristic is to delay the regular aging process of the transformer;

•  Usually manufactured with continuously transposed cable (CTC) in low voltage, producing especially lower electric losses and simplifying the sizing regarding the endurance to short circuit stresses;

• External coatings for the harshest environments, upon specification;

• Layout developed to adapt to any configuration (position of the command and control circuit box, radiators, conservator, high and low-voltage bushings, etc.);

• Option of renewable based, ecologically correct, (natural or synthetic ester-based, biodegradable)  insulation fluid, presenting high safety level of flammability, with fire point twice as high as the one of mineral oil and self-extinguishing properties, thus reducing the risk of fire propagation.

WEG Advantages

Market leader in Brazil, WEG is able to meet any requirements for a wide range of applications and configurations.

The verticalization of the manufacturing processes (making the electrical insulating varnish, electric wires, conventional fin radiators, 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 of 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. 

• Industrial substations;

• Power generation, transmission and distribution substations.
