We wish you a pleasant end-of-year holiday. Audio and video engineering Deviating current loads can be converted using the factors listed in DIN You have no items in your xin cart. CUAL can be tin- and silver-plated. This facilitates maintenance of busbar connections. Domestic and commercial equipment. Exaggeratedly flat surfaces are not necessary for the connection, since the connection is clean and fixed.

In the case of vibrations etc. The creep behaviour of CUAL lies between that of copper and aluminium.

Company organization, management and quality. Depending on the individual case, we recommend consulting with us.

Construction materials and building Materials handling equipment We only use cookies when they are necessary. Therefore, cutting with every second saw tooth produces good results. Treatment of contact surfaces: The contact resistance is lower if the contact surfaces have medium coarseness RA 1.

Log In Sign Up. The data in this technical product information is based on our current knowledge and experience. The contact area should be flat, clean, and uniformly roughened. Recommendation for drilling Cutting speed: Due to the abundance of possible influences during its application, it does not release the processor nor the user from performing their own tests and trials.

DIN – European Standards

If the surfaces are pressed together to be connected without the Vaseline being removed, the excess Vaseline is pressed out and contributes to the sealing of the connection and to the protection against harmful effects. In fact, no maintenance may be necessary at all.

Dim with rectangular cross-section DIN Alert me in case of modifications on this product contact us.

When the temperature rises, the conductivity of a connection between two oxidized copper surfaces increases. Sufficient tension force prevents the screws from loosening by themselves. Deformations therefore occur during the binding process. In diin completed connection, the actual contact area is significantly smaller than that of the total surface area of the connection. DIN and CUAL bars may be slightly bent. Paint and colour industries It is generally advisable to tighten non-rusting screws with a torque wrench.

The template should be as close as possible to the shearing edge so that the material is adequately supported. Deburring is not necessary.

A slight improvement can be achieved here: The conductor temperature caries accordingly with higher or lower ambient temperature. In addition, sprung elements should be used that can maintain the required contact pressure. You must have JavaScript enabled in your browser to utilize the functionality of this website. Road vehicles engineering Recommendations for cutting Cutting speed: Energy and heat transfer engineering They ensure the different expansions between the screws and the bar and compensate for any potential relaxations of the metal.

Copper oxide has a considerably lower electrical resistance than aluminium oxide and a negative temperature resistance coefficient. Latest News of the Blog. Spring washers are preferable for obtaining a constant pressing force during the various thermal stresses.
