2. Advantages of 2000kVA three-phase dry transformer

• This transformer uses silicon corrugated iron with low foucault current loss combined with copper foil windings, steel core arranged in a ladder style, with very small gaps, so the machine's noise level is low and does not pollute the environment. like current oil transformers.
• Cast-Resin Transformers manufactured by MBT are designed by experienced industry-leading electrical engineers to optimize the components on the computer to help the machine achieve high accuracy during production installation and operation with maximum efficiency. Multi.
• MBT's Cast-Resin Transformers meet EU HD484 environmental standards for climatic (C0, C1, C2), environmental (E0, E1, E2) and fire resistance (F0, F1, F2) conditions. Thanks to that, this type of transformer can be commonly used in residential areas, high-rise buildings, commercial centers,...
• In addition, the 2000kVA three-phase Cast-Resin Transformers is also widely used in power distribution systems, self-use systems of power plants, excitation systems, railway locomotive power supply systems, subway cars, nuclear power plants. Cast-Resin Transformers are also commonly used in hotels, stadiums, petrochemical factories, airports, oil rigs, and are especially used in places with strict fire prevention requirements.
• In particular, the machine has strong short circuit protection and a high level of lightning protection, excellent moisture resistance thanks to its optimal design. The machine also has the ability to withstand strong overload during long-term operation.

3. Test report of 2000kVA three-phase dry transformer

• All dry transformers developed and supplied by MBT are tested in independent laboratories to international standards and have accredited test reports including:
• Tightness testing and pressure testing for enclosures for gas-filled transformers complying with IEC 60076-15
• Temperature rise test meets standards of TCVN 6306-2 and IEC 60076-2
• Typical testing of dielectrics meets TCVN 6306-3 and IEC 60076-3 standards
• Determination of noise level according to IEC 60076-10 for each air cooling method is guaranteed
• Determination of overload voltage transmission characteristics meeting standards of TCVN 6306-3:2006 and IEC 60076-3:2000
• Short circuit tolerance test meets TCVN 6306-5 and IEC 60076-5 standards
