Elpress Cu-connections and Copper Branch C-sleeves are produced from electrolytic 99.9% copper. Terminals and Through Connectors exist in a large variety of types for stranded as well as for flexible conductors. C-sleeves for earth conductor branch off also come in a large number of sized. If a standard type is not suitable, we produce tailor-made designs specific to the application.

Elpress logotype is included on the marking, also the die number. The other side of the C sleeve is marked with the size of the Cu wire that fits and the total area. When an adequate crimping is done with the right tool, Elpress’ crimping dies make an impression on the sleeve so that all connections can be checked afterwards.

In the tools, there is a built-in full closure system that ensures that the entire crimping process is completed – a prerequisite for professional and quality-assured work.

C sleeves patentedPatented Solution
All Elpress Copper Branch C-Sleeves are based on the patented solution of the previous C89 sleeve. The solution means that the edges of the sleeve overlap after the contact crimping has been done. This patented solution allows multiple joint combinations to be used in one and the same sleeve.

Update Program 2018
In the autumn of 2018, the program was updated by C-sleeves, where the number of sleeves was compressed from 41 to today being 8 sleeves. The number of dies needed to perform the contact crimping has also been reduced (BC16, BC11 and BC4 are deleted). The sleeves C6-10, C16-25, C25-50 (formerly C89) and C50-70 are tin plated and have a different appearance than our other C-sleeves.
