Once the transformer is successfully tested and qualified, the product is ready for shipping either by truck or sea-freight.
As a manufacturer, we understand the relevance that logistics represents to our customers. This is one of the reasons why Aisite has developed a large and qualified net work of suppliers that have the same values and targets.
Aisite takes care of all official documentation, depending on final destinations and delivery terms.

- Crate packing
- Seaworthy packing
Production process
The core
The iron core forms the central element of every transformer. High-grade, cold-rolled metal sheets are precision-cut using computer-controlled machines to ensure compliance with even the smallest tolerances. The individual sheets are then assembled into cores using the step-lap technique by our veteran workers. In this way, weachieve an especially good flux distribution at the joints, resulting in exceptionally low losses and minimal no-load noise.
Windings
Transformer windings are subject to extremely high electrical and mechanical stresses and must therefore be protected. The transformer windings of our transformers are made of copper or aluminum. Low-voltage windings are made fromfoil, and high-voltage windings are manufactured from round orstripprofile wire. The use of insulating paper partially coated with epoxy resin (diamond-dotted paper) bonds the winding into a compact block during the drying process and additionally increases the short-circuit capacity.
Encapsulation process
The encapsulation process is a key stage within the manufacturing process. Encapsulation is carried out under the most rigorous conditions in order to ensure optimum insulating and mechanical characteristics. The resin mix is prepared in a continuously monitored mixing plant where all the components are mixed together just before the encapsulation process. Inside the vacuum casting chamber, the resin is introduced into the mould. The components are mixed together just before the encapsulation process, this ensures that the viscosity of the resin when poured in the moulds is very low, filling interstices and allowing the finished winding to reach the lowest level of partial discharge. Once the casting is finished the coils are placed into the curing oven for the resin gel to cure, and acquire the optimal final electrical and mechanical properties.
Final assembly
The transformer’s core-and-coil assembly consists of the core, windings, and connecting cables.
Testing
Ourtransformers are dispatched to the customer only after successfully passing the final inspection and testing. Ourfactory has a high-voltage test bay, where our veteranspecialists conduct a wide range of tests, from voltage tests and temperature-rise tests, to special tests for insulation resistance, partial discharge measurement, harmonics, and noise level. Short-circuit tests are performed in internationally recognized and approved institutes. Ourtests in accordance with the applicable standards and provides our customers with additional certificates on request.
For laboratory- or on-site measurements of partial discharge at medium-and high voltage components according GB/T 7354-2003, VDE 0434, IEC 60270, EN 50178, VDE 0884, IEC60747-5-5, UL 1577 and others.
