Now, WEG is doing it again by releasing their latest product in the transformers line: WEG cast coil transformers. Why choose WEG? Because WEG WILL! Demand for electricity has increased dramatically over the years. WEG cast coil transformers are designed to work under harsh operating conditions while reducing installation and maintenance costs. The cast resin design allows for higher short circuit strength and overload capacity. WEG cast coil transformers are designed for commercial and industrial applications such as oil & gas plants, pulp & paper mills, industrial operations, wind farms, hospitals, airports, and business centers. Ratings are available through 3,000 kVA and 34.5 kV with thermal insulation ratings through class C (220° C). Features WEG cast coil transformers are safe, environmentally friendly transformers. Key features include: • Flawless operation under harsh environmental conditions • Fire safe (no insulating mineral oil) • Reduced installation costs – no fire protection or oil containment required • No risk of contaminant leakage or toxic gas emissions • High resistance to short circuits and high capacity to support overload • Lower partial discharges and higher safety rating Transformer Construction Core The transformer core is manufactured with grain-oriented magnetic steel, with high magnetic permeability, low losses, and insulated on both sides by a thin layer of organic material (carlyte). The cutting and assembly is performed at 45° angles using the step lap method to reduce losses, excitation current, and magnetic noise. Low Voltage Coils The low voltage coils are made with copper or aluminum foil with a thermal insulation system designed per operating conditions F, H, or C. The coils are pre-impregnated with epoxy resin, an excellent adhesive, which provides an optimum coil insulation and high mechanical strength. Winding leads are mechanically anchored, making them practical, compact and easily accessed for field maintenance. High Voltage Coils High voltage coils display excellent resistance to load variations, changes in temperature, corrosive substances and fire. Windings are made of laminated foils and have a low partial discharge level and provide excellent resistance to axial forces caused by short circuits. High voltage regulation is performed by switching external jumpers easily accessible on the back of the coils. Insulated copper or aluminum bars are used to connect coils. Cast Coil Transformers 3 www.weg.net Cast Coil Transformers Cast coil transformers are certified with C2, E2, or F1 ratings. Ratings depend on the transformer installation conditions. WEG cast coil transformers meet all applicable international standards such as: • IEEE-C57.12.01 • C2 transformers are suitable for operating temperatures as low as -25° C • ANSI-C89.2 • IEC-60076-11 • E2 transformers are suitable for operation in high levels of humidity (up to 95%) • IEC-726-11 • UL 1562 • F1 transformers are suitable for operation in highly flammable areas. In the event of a failure, F1 transformers extinguish coil fires after the feed circuit has been opened. WEG cast coil transformers are suitable for installation in a wide variety of applications; including: • Wind farms applications • Buildings and skyscrapers Thermal table types used in insulation epoxy coil casts transfromers Thermal Types Insulation Temperature (°C) F 155 H 180 C 220 WEG manufactures cast coil transformers with the following power ratings and insulation classes: • 500, 750, 1000, 1500, 2000, 2500, 3000 kVA in voltage classes 5, 15, 25 & 34.5 kV 60Hz. • For transformers greater than 3000 kVA and < 10MVA, please contact your sales representative for additional information. • Standard connections: Delta-Wye, Wye-Wye, Delta-Delta. • Additional connection arrangements available upon request. 4 1-800-ASK-4WEG • Public convention halls • Shopping centers • Stadiums • Hospitals and health care centers • Subways • Food and Beverage industries • Petrochemical applications • Data centers • Sewage plants and pump stations • Ships • Housing complexes www.weg.net Testing Testing standards: • IEEE/ANSI • NEMA • IEC Additional manufacturing and testing standards are available.
