DIN 43673-2:1982-02

However, the contact surfaces should be free of oxidation and grease. This facilitates maintenance of busbar connections. Energy and heat transfer engineering Paint and colour industries It is generally advisable to tighten non-rusting screws with a torque wrench. Company organization, management and quality.

Do not bend over sharp edges; only perform drilling and punching after bending; avoid sudden deformation pressure. Spring washers are preferable for obtaining a constant pressing force during the dn thermal stresses.

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. Audio and video engineering The contact pressure should be spread out across oversized washers. Shipbuilding and marine structures Aircraft and space vehicle engineering CUAL can be cut using the same method as aluminium.

We wish you a pleasant end-of-year holiday. Drilled holes and screw connections for busbars; Channel section busbars. You must have JavaScript enabled in your browser to utilize the functionality of this website.

In addition, sprung elements should be used that can maintain the required contact pressure.

In a completed connection, the actual contact area is significantly smaller than that of the total surface area of the connection. Sciences humaines et sociales, lettres. Log In Sign Up. We only use cookies when they are necessary.

Sufficient tension force prevents the screws from loosening by themselves. With the further use of our website you accept the usage of cookies. DIN and Exaggeratedly flat surfaces are not necessary for the connection, since the connection is clean and fixed.

In fact, no maintenance may be necessary at all. Rubber and plastic industries Construction materials and building The effective contact area is dim limited to the surface near the bolts. Fluid systems and components for general use Copper oxide has a considerably lower electrical resistance than aluminium oxide and a negative temperature resistance coefficient.

Therefore, cutting with every second saw tooth produces good results.

DIN – European Standards

The punching tool is constructed just like for flat copper bars. In the case of vibrations etc. 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. The template should be as close as possible to the shearing edge so that the material is adequately supported.

If this is not the case, you must clean the contact surfaces. Mechanical systems and components for general use Deburring is not necessary.

Any property rights and existing laws must be observed by the recipient of our products under their own responsibility. They ensure 4673 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. Torque for dih tightening of the screws and dimensions 43763 the washers Screw dimensions.

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