DIN and In the case of vibrations etc. In order to ensure good electrical contact between the busbars, it is necessary to penetrate the surface film of oxides, sulphides, and other 4373. JavaScript seems to be disabled in your browser.

Road vehicles engineering Log In Sign Up. Recommendation for drilling Cutting speed: The surfaces should be even but not polished.

Deviating current loads can be converted using the factors listed in DIN Shipbuilding and marine structures Glass and ceramics industries CUAL can be cut using the same method as aluminium.

Aircraft and space vehicle engineering The screws can be made of a wide variety of steel grades, brass, or bronze. Image Gallery Downloads Request Information.

The contact will therefore be fin if the surface is rough, has pressing lines, or has been knurled. They ensure the different expansions between the screws and the bar and compensate for any potential relaxations of the metal.

Due to their higher availability, steel screws are recommended. Company organization, management and quality. Alert me in case of modifications on this product contact us.

Fluid systems and components for general use Copper oxide has a considerably lower electrical resistance than aluminium oxide and a negative temperature resistance coefficient.

Audio and video engineering This facilitates maintenance of busbar connections. 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. Construction materials and building Depending on the individual case, we recommend consulting with us.

Mechanical systems and components for general use Drilled holes and screw connections for busbars; Channel section busbars. It is generally advisable to tighten non-rusting screws with a torque wrench. Busbars with rectangular cross-section DIN If this is not the case, you must clean the contact surfaces.

Domestic and commercial equipment. In a completed connection, the actual contact area is significantly smaller than that of the total surface area of the connection. In addition, sprung elements should be used that can maintain the required contact pressure.

The tension discs maintain the tension force diin a defined range and are therefore also recommended for the fixing of screws.

DIN – European Standards

Spring washers are preferable for obtaining a constant pressing force during the various thermal stresses. The conductor temperature caries accordingly with fin or lower ambient temperature.
