Torque for the tightening of the screws and dimensions of the washers Screw dimensions. However, the contact surfaces should be free of oxidation and grease. Textile and leather technology Busbars with rectangular cross-section DIN Rubber and plastic industries Aircraft and space vehicle engineering Due to their higher availability, steel screws are recommended.
The conductor temperature caries accordingly with higher or lower ambient temperature. 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.
Shipbuilding and marine structures DIN and If this is not the case, you must clean the contact surfaces. Spring washers are preferable for obtaining a constant pressing force during the various thermal stresses. Alert me in case of modifications on this product contact us.
ISOFLEXX® Classic Ampacity
In the case of vibrations etc. Latest News of the Blog. Image Gallery Downloads Request Information. Health care technology CUAL can be cut using the same method as aluminium. A legally binding guarantee of certain properties or of suitability for a specific purpose cannot be derived from our information.
Materials handling equipment The tension discs maintain the tension force within a defined range and are therefore also recommended for the fixing of screws. 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. The data in this technical product information is based on our current knowledge and experience.
Sufficient tension force prevents the screws from loosening by themselves. The contact pressure should be spread out across oversized washers.
This facilitates maintenance of busbar connections. CUAL bars may be slightly bent. The effective contact area is normally limited to the surface near the bolts.
CUAL bars – EN | anoxal
Fluid systems and components for general use Deviating current loads can be converted using the 34673 listed in DIN Do not bend over sharp edges; only perform drilling and punching after bending; avoid sudden deformation pressure. The contact resistance is lower if the contact surfaces have medium coarseness RA 1. Treatment of contact surfaces: Depending on the individual case, we recommend consulting with us. The surfaces should be even but not polished. Glass and ceramics industries The screws can be made of a wide variety of steel grades, brass, or bronze.
Recommendation for drilling Cutting speed: Therefore, cutting with every second saw tooth produces good results. Drilled holes and screw connections for busbars; Channel section busbars. Construction materials and building The creep behaviour of CUAL lies between that of copper and aluminium. The contact will therefore be better if the surface is rough, has pressing lines, or has been knurled.
CUAL can be tin- and silver-plated. Packaging and distribution of goods A slight improvement can be achieved here: The contact between the surfaces is initially limited to the tip dim each surface, which are therefore subjected to a significantly higher pressure than the average pressure of the connection.
Energy and heat transfer engineering You have no items in your shopping cart. These should be higher strength 8.
When the temperature rises, the conductivity of a connection between two oxidized copper surfaces increases.
