MEDIUM VOLTAGE DRYTYPE TRANSFORMERS
The dry-type transformers with windings embedded vacuum, are designed according to the European standards and refer to EN 60076-11 and EN50541-1.
The type of construction of our transformers allows us to obtain values significantly better respect what norms request. All testing procedures are performed according to the routine tests prescribed by the regulations, thanks to a fully equipped rehearsal room we can make the type tests in accordance with the specific customer requirements with the presence or absence of certification bodies such as DNV, Loyid Register, and RINA.
The production includes machines up to 24 KVA maximum voltage, the magnetic core is step lap type (45°), which ensures low iron losses and a very low noise level.
MT windings are made with copper or aluminum conductors insulated by Nomex; this ensures compactness and reliability.
Incorporation process is carried out under vacuum.
BT windings are made, depending on the rated power, with wires, strips, or copper and/or aluminum sheets insulated by Nomex or DMD and subsequently impregnated in autoclave.
For a higher level of insulation and resistance to the environmental agents, is also possible to incorporate in resin LV windings.
The machines are designed to operate with a natural air cooling, however, it is possible, in case of heavy duty load, to insert in the frame a fans in the bar in order to create a greater cooling of the windings.
Manufacturer process allows to use our machines in Rai/ system, Marine, Solar and Wind applications.
All machines can be fitted with devices of measurement of temperatures, metal box containing self-supporting with various IP protection degrees coated with epoxy resins and special treatment for marine environments.
