Assembly

High Voltage Potting & Coating (HVPC) has the knowledge and facilities to assemble transformers, oil-filled units, silicon units, epoxy-filled units and circuit boards. You can contact us for assembly according to your own specifications. If these specifications are not yet clear to you, we will be happy to develop the assembly specifications in cooperation with you.

The assembly of your product can be part of the entire development process of your product, but HVPC can also take care of only the assembly. We offer the possibility to have direct contact with the expert within HVPC so that the lines of communication are as short as possible.

The assembly process of HVPC

At HVPC, we usually assemble wound transformers or other components before they are treated with epoxy, silicone or oil. We have specific high-quality assembly techniques. These ensure that breakdown(field strength) and contamination are prevented.

Assembly takes place according to various standards such as NEN but also specific MIL specifications. These techniques, together with calibrated and correct tools, ensure that it becomes a high-quality product. These assembly techniques in combination with the expertise of our employees ensure a good product.

For assembly, we adhere to standards such as MIL, IPC and NEN. This is to ensure that high-quality products are made and delivered both outside and inside the cleanroom. All prepared and assembled products are checked and, where possible, tested before further processing takes place. This makes it possible to repair the product in the interim and to ensure the product meets the requirements. Required equipment and tools are calibrated and periodically maintained. This ensures, among other things, high-quality compression connections and soldered connections.

Assembly under cleanroom conditions

The assembly of oil-filled units, epoxy cast units, silicon units, circuit boards and transformers takes place under cleanroom conditions. It has been proven that by working in a dust-free environment, the quality and high-voltage behaviour is good. Contamination, by working outside the cleanroom, can cause the product to discharge more during the Partial Discharge measurement. The impact of this is that the lifespan of the product is greatly reduced. The same applies to inductive components that are partially or completely cast in epoxy/silicone. Therefore, working in a cleanroom is necessary.

HVPC has chosen to manufacture inductive components under cleanroom conditions. Most inductive components are then assembled in a high-voltage unit. But inductive components are also assembled into a pulse forming network (PFN), which operates in a high-voltage unit. This assembly also takes place in the same cleanroom. After this, the PFN is casted into a medium such as oil, silicone or epoxy. This is often necessary because the energy generated by the PFN to the load is enormous.

Without insulation in between, the PFN will not work for a long time. HVPC has many years of experience in both testing and calculating PFN networks. Making inductive components together with the matching capacitors is also one of HVPC’s competencies.

The assembly ofproducts which do not require the cleanroom isalso carried out at HVPC. Think of the wiring of power supplies, low voltage transformers and some printed circuit boards.
