Electrical equipment production and assembly

Brazing means joining metals using solder with a melting point above 450 °C. Unlike soldering, where a natural gas flame and air are sufficient, brazing uses hot oxygen-acetylene or oxygen-hydrogen flame.

We can braze almost all metals except zinc alloys, for which soldering is suitable. Connecting different types of metals is not a problem thanks to brazing and the use of brazing solders based on copper, silver, nickel, lead, and precious metals. We achieve the best results by vacuum brazing.

Crimping means the joining a connector and an electrical conductor or a high-frequency coaxial cable for signal transmission by crimping. Crimping is suitable for a variety of diameters and creates high-quality, safe, and durable joints.

We use various forms for crimping – e.g., hexagonal, square, round, trapezoidal, W-shaped, or double W-shaped, etc. Crimping is also sometimes called cold melting. At CENTES we usually crimp various types of cables, such as flat, coaxial, flexi.

Toroidal (wound) transformers are transformers that have a toroidal core. Compared to conventional transformers with EI and M type cores, they have minimal energy losses, higher efficiency, and longer service life. Therefore, they are often used to produce halogen and LED bulbs.

We at CENTES usually provide the production of toroidal transformers for outputs from 30 W to 1200 W. The maximum width of the toroid is 38 mm. We also offer toroids wound from sheet metal strips. If you provide us with full documentation, we will also produce atypical toroidal transformers for you exactly according to your requirements.

As part of electrical equipment production and assembly, we also deal with winding coils and transformers. We use a high-quality high-speed winder for linear winding coils and transformers. We usually wind coils with a 0.2 mm to 2.5 mm wire diameter.

Most transformer coils that we produce go to the supplier of electronic testing and measuring instruments, information technology and radio communications, ROHDE & SCHWARZ závod Vimperk, s.r.o. If you provide us with project documentation, we will be happy to help you wind your coils.

Coaxial cables have one cylindrical outer conductor and one wire or tubular inner conductor. The outer and inner conductors are separated by a non-conductive layer called a dielectric. Coaxial cables can range in diameter from a few millimetres to several tens of centimetres.

Our company provides assembly of coaxial cables for power supplies of transmitting or receiving antennas, leads for television antennas, television distribution, cable television and telephony. We usually assemble coaxial cables for computer networks.
