Cast resin transformer cooling The manufacturing process locks the windings in a strong epoxy resin with high dielectric strength, The cyclical expansion and contraction with the heating One challenge, however, is the limited cooling capacity of air and the relatively weak thermal conductivity of resin, which makes CRTs vulnerable to overheating. GENERAL TECHNICAL DATA Based on a selection of basic transformer designs the transformers can be efficiently adapted or extended to the respective requirements. 5kV medium voltage level. Add to my manuals. HE 10 Insulation class 12 kV 11 Insulation class 17. SGB-SMIT Group is able to deliver Cast Resin Transformers (from production sites in Germany, Malaysia, the USA, China, Cooling of conventional technology cast resin transformers with continuously Cast resin transformers are constructed aligned to industry regulations and standards and we present a wide offering to customer Our swan neck type transformer housing introduced by ATL and now widely duplicated across industry provides a degree of cooling in these naturally cooled dry type transformers while maintaining superior levels of • No cooling fluids Because they have no cooling fluids cast resin transformers do not present risks of pollution and drastically reduce their contribution when there is a fire, as compared with transformers using insulating liquid. The following tests are performed on each cast resin transformer: • Resistance Measurement* • Voltage Ratio • Polarity & Phase-Relation Test • No-Load Loss and Excitation Current Test • Induced Voltage Siemens is breaking new ground in the area of cast- resin transformers through its use of the ADWF*) cooling method. Among various types of transformers, the dry-type transformer or cast resin transformer are the most commonly used due to their numerous benefits such as enhanced security, prevent from explosion and damaged. HV Delta connected, LV Star connected with Dyn 11 vector COOLING The cast resin transformers are usually cooled with natural cooling by air (AN), though certain cases require the use of fans for cooling with forced air (AF).
