Highly flexible high current copper connectors
in solderless pressed design

Construction and application

druseidt high current copper connectors are extremely flexible components and are manufactured out of braided copper tapes with a wire-Ø of 0,07 mm respectively 0,10 mm. Caused by the using of wires which such small diameters and the special conductor construction consisting out of several layers of braids we get elements which have a very large surface. So one of the main characteristics of the druseidt connectors is beside the flexibility, the high current capacity of the components. The contact areas are equipped with seamless solderless pressed CU-ETP tubes. Whether made out of braids or round stranded cables, whether in insulated or non insulated design, whether with coated or uncoated surfaces, we are able to manufacture a large number of connectors from 25 mm² up to 6000 mm² with contact areas from 20 mm up to 200 mm width. We manufacture in large as well as small quantities in length according to your wishes. Ready assembled connectors made out of round stranded copper cables can be delivered with different wire-Ø up to a conductor cross-section of 1000 mm². Our connectors are used nearly in all kinds of application for high current transfer. They have become particularly well established as connectors in switchgears and between transformers, generators, rectifiers, switching devices and prefabricated power networks. They can compensate expansions caused by an increase of temperature as well as movements caused by a vibration of switchgears, transformers or generators.

Druseidt press-technology

The for the manufacturing of our connectors used druseidt press-technology guarantees extreme compressing and an optimal contact resistance. As an opposite of the typical method by using terminal lugs this procedure makes a fully pressed braid-integrated contact-area. Through the very high pressure the space which contains air between the wires is so much compressed, that no harmful gases or other environmental influences can go inside. The crimping process is realized without using additives like tin or soldering and welding additives. We use exclusively materials of same analysis and same conductivity of circa 57 S (braids and tubes).

Consultation and construction

Your wishes are the guidelines for all our activities. So we offer extensive consultations as well as a constructive support through our construction department when planing projects or new products. We realize high current solutions for different kinds of applications in cooperation with our customers.

Connectors in special design

Additionally to our extensive standard program we offer individual constructed components and solutions for solving your problems. Our diverse manufacturing processes facilitate the production of highly flexible braided connectors according to your wishes and your applications. Following some possibilities for connectors in special design:

• braided connectors with variable contact areas to connect switchgears with smaller connection-bar to busbar systems (e.g. one side contact area width 80 mm and 100 mm at the other side).
• braided connectors with one or more branched off conductors with different contact areas from 20 mm up to 100 mm width suitable for a current capacity between 160 A and 2600 A.
• braided connectors with several contact areas
• braided connectors with special clamps for clamping graphite electrodes or current bars in round shaped design
• braiding connectors consisting out of several round stranded copper cables
• braided connectors with bended contact areas
• braided connectors in shaped design (e.g. 90° or 180°) for welding machines or transformer connections
• braided connectors with special insulation materials and/or with coated contact areas (tin-, nickel-, silver- or gold plated)
