Depending on the individual case, we recommend consulting with us. Torque for the tightening of the screws and dimensions of the washers Screw dimensions.

Log In Sign Up. Therefore, cutting with every second saw tooth produces good results.

The creep behaviour of CUAL lies between that of copper and aluminium. Deviating current loads can be converted using the factors listed in DIN Deburring is not necessary. Our offices will be closed from December 24, to January 2, inclusive.

CUAL bars – EN | anoxal

DIN and It is generally advisable to tighten non-rusting screws with a torque wrench. Paint and colour industries It is important that the yield strength of the material is not exceeded; a contact pressure of max.

In order to ensure good electrical contact between the busbars, it is necessary to penetrate the surface film of oxides, sulphides, and other contaminants. Shipbuilding dni marine structures CUAL bars may be slightly bent. Deformations therefore occur during the binding process. The conductor temperature caries accordingly with higher or lower ambient temperature.

Copper-Aluminium Bars (CUAL)

Due to the abundance of possible influences during its application, it 43637 not release the processor nor the user from performing their own tests and 436673. 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.

Company organization, management and quality. They ensure the different expansions between the screws and the bar and compensate for any potential relaxations of the metal. Petroleum and related technologies JavaScript seems to be disabled in your browser.

Do not bend over sharp edges; only perform drilling and punching after bending; avoid sudden deformation 34673. Sciences humaines et sociales, lettres. In fact, no maintenance may be necessary at all.

Alert me in case of modifications on this product contact us. Sufficient tension force prevents the screws from loosening by themselves. Energy and heat transfer engineering CUAL can be tin- and silver-plated.

DIN – European Standards

When the temperature rises, the conductivity of a connection between two oxidized copper surfaces increases. Since CUAL has a copper plating, it has the same outstanding contact properties as copper, and so CUAL bars can be used in the same way as copper bars. We only use cookies when they are necessary. Latest News of the Blog. The screws can be made of a wide variety of steel grades, brass, or bronze. For a given contact pressure, a copper surface 433673 a contact resistance that is times lower than that of aluminium.

The contact area should be flat, clean, and uniformly roughened. The contact between the surfaces is 4373 limited to the tip of each surface, which are therefore subjected to a significantly higher pressure than the average pressure of the connection.

You have no items in your shopping cart. Aircraft and space vehicle engineering Mining and minerals The template should be as close as possible to the shearing edge so that the material is adequately supported. Glass and ceramics industries In a completed connection, the actual contact area is significantly smaller than that of the total surface area of the 436773.

Materials handling equipment The contact resistance is lower if the 433673 surfaces have medium coarseness RA 1. With the further use of our website you accept the usage of cookies.
