Spacers with rubber inserts reduce vibration transmission between core and windings, hence reducing transformer working noise.7. In this case it is useful to get in contact with us for technical data confirmation.1. The lower opening must be located close to the transformer, as low as possible, while the upper one must have a cross-section 15% greater to compensate for the lesser density of the hot air.No condensation on the transformer, negligible pollution.
On request LV connection ready for Zucchini busbars.14. The epoxy resin insulation has a high inflammability point and high self extinguishing characteristics, making the transformer maintenance-free.11. Off load tap changing links on the HV winding allow step by step regulation to suit supply voltage.8. Installation in dry and clean ambient.HV coil of a 1600 kVA transformer, after a Class F1 fire resistance test.The transformer is subject to severe condensation or to heavy pollution or to a combination of both.The transformer is unsuitable for operation at temperatures below - 5°C but may be exposed to –25°C during transportation and storage.The transformer is suitable for operation, transport and storage down to –25°C.No fire hazard is envisaged and no measures to limit the flammability are taken.The transformer is subject to fire hazard and a restricted flammability is required. In addition, Electrical Power Systems manufactures transformers up to 5000 kVA in the 36 kV series.The general details of our transformers are the follows: three-phase, continuous operation, indoor installation, degree of protection IP00, frequency 50 Hz, AN cooling, thermal Class F.The transformers described in this catalogue are designed and tested in accordance to the European Union Harmonisations Documents HD 538 and HD 464 as well as IEC 726, IEC 76 standards. LV windings of aluminium foil and insulation material, impregnated under vacuum.4. The frame is ready to install an integral steel enclosure.15.

Insulating materials for class F products, winding over temperature of 100° K.A dry-type transformer is one in which the magnetic circuit and the windings are not immersed in an insulating liquid, IEC 726.This catalogue refers to cast-resin transformers with rated power levels between 100 and 2500 kVA, with higher voltage for the material, up to and including 36 kV. LV connections at the top (standard production), or at the bottom (on request).5. Main structure and trolley frame manufactured of robust painted steel.9. The operating temperature is controlled with Pt100 or PTC probes, placed in each of the LV windings.13. Core composed of three columns made in grain oriented magnetic steel sheets, also available with much reduced losses.3. Specific figures are not given for this parameter because of the wide variety of voltages used. Different powers, as well as different primary and secondary tensions, are nonetheless part of our production range and application experience.
Transformers can be supplied on demand to run at two different primary voltages.The no load voltage is allocated at 400 V, though other voltages can be supplied on demand.When usage requires two voltages, transformers with two simultaneous voltages can be supplied.In this case no-load voltages are set to 400 and 231 V.• For rated power levels of 160 kVA or less: Yzn11 or Dyn11• For rated power levels of 160 kVA or less: Yzn11 or Dyn11As per IEC 76, BS 171 and VDE 532 standards these are set in accordance with the highest voltage for the material, being the level immediately above the rated voltage.SNO-Energietechnik transformers are in the F insulation class, which, according to IEC 726, have a temperature rise of 100 K.Cast resin transformers have the following advantages:• Monitoring equipment with temperature indication and alarm and tripping contactsIn order to avoid excessive and damaging heating, and for correct operation, it is essential to dissipate the thermal energy produced by the transformer during operation.The natural circulation of air is directed from the lower part to the upper (chimney effect) and the dimensions of the openings are according to the losses to be dissipated and the temperature of the air entering and leaving the cell. Light (Layout Lighting Sherpa), Air Circuit Breaker (ACB)Switch, Socket MCCB’S (Moulded Case Circuit Breaker (MCCB)Thanks to the long experience of SHERPA and to the sophisticated calculation and design techniques used, our transformers for distribution, rectification and traction can be provided in a very large range of sizes, primary and secondary tensions, insulation classes and losses.Following tables present the technical features of some transformers in our production range. They were chosen according to norm requests and to market preferences in power distribution sector for the main industrial countries.
HV windings in coils of aluminium band, cast in resin under vacuum.2.
