Intedat editorial summary
The Intedat editorial summary complements publicly verifiable facts with additional business and industry context.
BV elektronik s.r.o. is one of the established Czech manufacturers of wound components. It was founded in 1993 as a family business, gradually concentrated its production in Holice in the Pardubice region and is still run by the same two managing directors who founded it.
The core of its business is in-house design, development and production of transformers and chokes. The range covers single-phase and three-phase transformers, toroidal transformers, power chokes for low-frequency applications, transformers and chokes for high-frequency applications and instrument transformers, and according to the company it contains thousands of items.
From a commercial perspective, it is notable how many follow-up activities the company covers under one roof: its own development department and toolroom, production of magnetic cores, winding, a mechanical workshop, laser cutting, water jet cutting, plastic injection moulding and 3D printing of prototypes. Customers can therefore handle design, sampling and series production, including mechanical parts, with a single supplier.
The company is strongly export-oriented and supplies customers throughout Europe and in other parts of the world. According to its own careers website, it is expanding production with a new plant in Tuněchody and launching the production of oil transformers, which suggests a move into power equipment as well.
Main products and business areas
A structured overview of the product lines and manufacturing areas publicly presented by BV elektronik on its website.
Three-phase transformers
Three-phase transformers form the second basic product line. The company supplies them in versions matching the required output, voltage and cooling method for industrial machines, technological units and energy applications.
Toroidal transformers
Toroidal transformers are listed on the website as a separate line. Thanks to their compact construction they are used wherever dimensions, weight and electrical properties matter, typically in electronics and measuring technology.
Power chokes for LF applications
Power chokes for low-frequency applications are intended for customers dealing with inductive components for industrial, energy or electronic assemblies with specific electrical and mechanical requirements.
Transformers and chokes for HF applications
The line for high-frequency applications extends the offer towards switching power supplies, converters and other devices where the wound component has to be designed with regard to higher operating frequencies and the design constraints of the device.
Instrument transformers
Instrument transformers are listed on the website as a separate product line, usable for measurement, control, monitoring systems and energy applications.
Custom development, sampling and prototypes
According to the website, the company’s technicians prepare the solution that best matches the customer’s requirements and produce the required samples at short notice. These are handed over together with photographic documentation and measurement protocols for testing on the customer’s target product. For prototype parts the company uses 3D printing with FDM, SLA, MJF and SLM technologies, which according to the website substantially shortens the development time of new products.
Production of magnetic cores
For core production the company uses grain-oriented laminations 0.30 mm and 0.27 mm thick, purchased according to the ČSN EN 10107 standard, and manufactures toroidal, oval and rectangular cores. For toroidal cores the website states an outer diameter of 18 to 90, an inner diameter of 12 to 740 mm and a height of 5 to 100 mm.
Coil winding and edgewise winding
On its winding machines the company winds coils of various shapes and sizes and has multi-spindle winders able to wind several wires accurately. Mandrels are produced to customer requirements in its own toolroom. The machine for edgewise winding of flat conductor was built by its own development department; this technology makes it possible to achieve a large cooling area of the winding and thus optimise the dimensions of the finished product, particularly in the case of forced cooling.
Mechanical parts, laser and water jet cutting
According to the website, the mechanical workshop is equipped with CNC machines, a press brake, milling machines, lathes and other professional equipment and produces mechanical parts to customer specification. A fibre laser with an output of 6 to 20 kW cuts carbon steels, stainless steels and non-ferrous alloys on a working area of 3000 mm x 1500 mm; the water jet with a cutting area of 3050 mm x 1530 mm processes rubber, Pertinax, glass, stone materials, PVC, foams and metals.
Plastic injection moulding and overmoulding
On its injection moulding machine the company produces bobbins and other smaller parts from various types of plastic granulates. It also offers overmoulding of the customer’s product in plastic for better electrical and mechanical protection and a higher IP rating.
